          1.  Introduction

               Recently,  you  have  begun to find yourself unfulfilled and
          distant in your daily occupation.  Strange dreams of prospecting,
          stealing,  crusading,  and  combat have haunted you in your sleep
          for many months, but you aren't sure of the reason.   You  wonder
          whether  you have in fact been having those dreams all your life,
          and somehow managed to forget about them until now.  Some  nights
          you awaken suddenly and cry out, terrified at the vivid recollec-
          tion of the strange and powerful creatures that seem to be  lurk-
          ing  behind  every  corner  of  the dungeon in your dream.  Could
          these details haunting your dreams be real?  As each night  pass-
          es,  you feel the desire to enter the mysterious caverns near the
          ruins grow stronger.  Each morning, however, you quickly put  the
          idea  out  of  your head as you recall the tales of those who en-
          tered the caverns before you and did not return.  Eventually  you
          can  resist  the yearning to seek out the fantastic place in your
          dreams no longer.  After all, when other  adventurers  came  back
          this  way after spending time in the caverns, they usually seemed
          better off than when they passed through the first time.  And who
          was to say that all of those who did not return had not just kept
          going?

               Asking around, you hear about a bauble, called the Amulet of
          Yendor  by  some, which, if you can find it, will bring you great
          wealth.  One legend you were told even mentioned that the one who
          finds  the  amulet  will be granted immortality by the gods.  The
          amulet is rumored to be somewhere beyond the Valley of  Gehennom,
          deep  within  the Mazes of Menace.  Upon hearing the legends, you
          immediately realize that there is some profound and  undiscovered
          reason that you are to descend into the caverns and seek out that
          amulet of which they spoke.  Even if the rumors of  the  amulet's
          powers are untrue, you decide that you should at least be able to
          sell the tales of your adventures to the local  minstrels  for  a
          tidy  sum,  especially if you encounter any of the terrifying and
          magical creatures of your dreams along the way.   You  spend  one
          last  night  fortifying  yourself at the local inn, becoming more
          and more depressed as you watch the odds of  your  success  being
          posted on the inn's walls getting lower and lower.

               In  the  morning you awake, collect your belongings, and set
          off for the dungeon.  After several days  of  uneventful  travel,
          you  see the ancient ruins that mark the entrance to the Mazes of
          Menace.  It is late at night, so you make camp  at  the  entrance
          and  spend the night sleeping under the open skies.  In the morn-
          ing, you gather your gear, eat what may be your  last  meal  out-
          side, and enter the dungeon....

          2.  What is going on here?

               You have just begun a game of NetHack.  Your goal is to grab
          as much treasure as you can, retrieve the Amulet of  Yendor,  and
          escape the Mazes of Menace alive.

               Your abilities and strengths for dealing with the hazards of
          adventure will vary with your background and training:

               Archeologists understand dungeons pretty well; this  enables
          them  to  move  quickly  and sneak up on the local nasties.  They
          start equipped with the tools for a proper scientific expedition.

               Barbarians are warriors out of the hinterland,  hardened  to
          battle.   They  begin  their  quests  with  naught  but  uncommon
          strength, a trusty hauberk, and a great two-handed sword.

               Cavemen and Cavewomen start with exceptional  strength  but,
          unfortunately, with neolithic weapons.

               Healers  are wise in medicine and apothecary.  They know the
          herbs and simples that can restore  vitality,  ease  pain,  anes-
          thetize, and neutralize poisons; and with their instruments, they
          can divine a being's state of health or sickness.  Their  medical
          practice earns them quite reasonable amounts of money, with which
          they enter the dungeon.

               Knights are distinguished  from  the  common  skirmisher  by
          their  devotion  to  the ideals of chivalry and by the surpassing
          excellence of their armor.

               Monks are ascetics, who by rigorous practice of physical and
          mental disciplines have become capable of fighting as effectively
          without weapons as with.  They wear no armor but make up  for  it
          with increased mobility.

               Priests  and Priestesses are clerics militant, crusaders ad-
          vancing the cause of righteousness with  arms,  armor,  and  arts
          thaumaturgic.   Their  ability to commune with deities via prayer
          occasionally extricates them from peril, but can also put them in
          it.

               Rangers are most at home in the woods, and some say slightly
          out of place in a dungeon.  They are, however, experts in archery
          as well as tracking and stealthy movement.



          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                               3



               Rogues  are  agile  and  stealthy thieves, with knowledge of
          locks, traps, and poisons.  Their  advantage  lies  in  surprise,
          which they employ to great advantage.

               Samurai  are  the elite warriors of feudal Nippon.  They are
          lightly armored and quick, and wear the dai-sho,  two  swords  of
          the deadliest keenness.

               Tourists  start out with lots of gold (suitable for shopping
          with), a credit card, lots of food, some maps, and  an  expensive
          camera.  Most monsters don't like being photographed.

               Valkyries  are hardy warrior women.  Their upbringing in the
          harsh Northlands makes them strong, inures them  to  extremes  of
          cold, and instills in them stealth and cunning.

               Wizards  start out with a knowledge of magic, a selection of
          magical items, and a particular affinity for  dweomercraft.   Al-
          though seemingly weak and easy to overcome at first sight, an ex-
          perienced Wizard is a deadly foe.

               You may also choose the race of your character (within  lim-
          its; most roles have restrictions on which races are eligible for
          them):

               Dwarves are smaller than humans or elves, but are stocky and
          solid  individuals.   Dwarves'  most notable trait is their great
          expertise in mining and metalwork.  Dwarvish armor is said to  be
          second in quality not even to the mithril armor of the Elves.

               Elves  are agile, quick, and perceptive; very little of what
          goes on will escape an Elf.  The quality of  Elven  craftsmanship
          often gives them an advantage in arms and armor.

               Gnomes  are  smaller  than but generally similar to dwarves.
          Gnomes are known to be expert miners, and it is known that a  se-
          cret  underground  mine  complex built by this race exists within
          the Mazes of Menace, filled with both riches and danger.

               Humans are by far the most common race of the surface world,
          and  are  thus  the norm to which other races are often compared.
          Although they have no special abilities, they can succeed in  any
          role.

               Orcs  are  a  cruel and barbaric race that hate every living
          thing (including other orcs).  Above all others, Orcs hate  Elves
          with  a  passion unequalled, and will go out of their way to kill
          one at any opportunity.  The armor and weapons fashioned  by  the
          Orcs are typically of inferior quality.

          3.  What do all those things on the screen mean?

               On  the screen is kept a map of where you have been and what
          you have seen on the current dungeon level; as you  explore  more


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                               4



          of the level, it appears on the screen in front of you.

               When  NetHack's  ancestor  rogue  first appeared, its screen
          orientation was  almost  unique  among  computer  fantasy  games.
          Since  then,  screen  orientation has become the norm rather than
          the exception; NetHack continues  this  fine  tradition.   Unlike
          text  adventure games that accept commands in pseudo-English sen-
          tences and explain the results in words, NetHack commands are all
          one  or  two keystrokes and the results are displayed graphically
          on the screen.  A minimum screen size of 24 lines by  80  columns
          is  recommended;  if  the  screen is larger, only a 21x80 section
          will be used for the map.

               NetHack can even be played by blind players,  with  the  as-
          sistance of Braille readers or speech synthesisers.  Instructions
          for configuring NetHack for the blind are included later in  this
          document.

               NetHack generates a new dungeon every time you play it; even
          the authors still find it an entertaining and exciting  game  de-
          spite having won several times.

               NetHack  offers  a  variety of display options.  The options
          available to you will vary from port to port,  depending  on  the
          capabilities  of  your hardware and software, and whether various
          compile-time options were enabled when your executable was creat-
          ed.  The three possible display options are: a monochrome charac-
          ter interface, a color character interface, and a  graphical  in-
          terface using small pictures called tiles.  The two character in-
          terfaces allow fonts with other characters to be substituted, but
          the  default  assignments use standard ASCII characters to repre-
          sent everything.  There is no difference between the various dis-
          play options with respect to game play.  Because we cannot repro-
          duce the tiles or colors in the Guidebook, and because it is com-
          mon  to  all ports, we will use the default ASCII characters from
          the monochrome character display when  referring  to  things  you
          might see on the screen during your game.

               In  order  to  understand what is going on in NetHack, first
          you must understand what NetHack is doing with the  screen.   The
          NetHack  screen  replaces  the "You see ..." descriptions of text
          adventure games.  Figure 1 is a sample of what a  NetHack  screen
          might  look  like.   The  way the screen looks for you depends on
          your platform.

          3.1.  The status lines (bottom)

               The bottom two (or three) lines of the screen contain sever-
          al  cryptic pieces of information describing your current status.
          Figure 1 shows the traditional two-line  status  area  below  the
          map.  Figure 2 shows just the status area, when the statuslines:3
          option has been set (not all interfaces support this option).  If
          any  status line becomes wider than the screen, you might not see
          all of it due to truncation.  When the numbers  grow  bigger  and
          multiple conditions are present, the two-line format will run out
          of room on the second line, but statuslines:2 is the default  be-
          cause  a  basic  24-line terminal isn't tall enough for the third
          line.

               Here are explanations of what the various status items mean:

          Title
               Your character's name and  professional  ranking  (based  on
               role and experience level, see below).

          Strength
               A  measure of your character's strength; one of your six ba-
               sic attributes.  A human character's  attributes  can  range
               from  3  to 18 inclusive; non-humans may exceed these limits
               (occasionally you may get super-strengths of the form 18/xx,
               and  magic  can  also  cause attributes to exceed the normal
               limits).  The higher your strength, the  stronger  you  are.
               Strength  affects  how  successfully  you  perform  physical
               tasks, how much damage you do in combat, and how  much  loot
               you can carry.



          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                               6



          Dexterity
               Dexterity  affects  your  chances to hit in combat, to avoid
               traps, and do other tasks requiring agility or  manipulation
               of objects.

          Constitution
               Constitution  affects  your ability to recover from injuries
               and other strains on your stamina.  When strength is low  or
               modest,  constitution  also  affects how much you can carry.
               With sufficiently high strength, the contribution to  carry-
               ing capacity from your constitution no longer matters.

          Intelligence
               Intelligence  affects  your  ability to cast spells and read
               spellbooks.

          Wisdom
               Wisdom comes from your practical experience (especially when
               dealing with magic).  It affects your magical energy.

          Charisma
               Charisma affects how certain creatures react toward you.  In
               particular, it can affect the prices shopkeepers offer you.

          Alignment
               Lawful, Neutral, or Chaotic.  Often, Lawful is taken as good
               and Chaotic as evil, but legal and ethical do not always co-
               incide.  Your alignment influences how other monsters  react
               toward you.  Monsters of a like alignment are more likely to
               be non-aggressive, while those of an opposing alignment  are
               more likely to be seriously offended at your presence.

          Dungeon Level
               How deep you are in the dungeon.  You start at level one and
               the number increases as you  go  deeper  into  the  dungeon.
               Some  levels  are  special, and are identified by a name and
               not a number.  The Amulet of Yendor is reputed to  be  some-
               where beneath the twentieth level.

          Gold
               The  number  of  gold  pieces you are openly carrying.  Gold
               which you have concealed in containers is not counted.

          Hit Points
               Your current and maximum hit points.   Hit  points  indicate
               how  much  damage you can take before you die.  The more you
               get hit in a fight, the lower they get.  You can regain  hit
               points  by  resting,  or  by  using certain magical items or
               spells.  The number in parentheses  is  the  maximum  number
               your hit points can reach.

          Power
               Spell  points.  This tells you how much mystic energy (mana)
               you have available for spell casting.  Again,  resting  will

               regenerate the amount available.

          Armor Class
               A measure of how effectively your armor stops blows from un-
               friendly creatures.  The lower this number is, the more  ef-
               fective the armor; it is quite possible to have negative ar-
               mor class.  See the Armor subsection of Objects for more in-
               formation.

          Experience
               Your  current  experience  level.   If the showexp option is
               set, it will be followed by a slash and  experience  points.
               As  you  adventure,  you gain experience points.  At certain
               experience point totals, you gain an experience level.   The
               more experienced you are, the better you fight and withstand
               magical attacks.  (By the time  your  level  reaches  double
               digits,  the  usefulness  of  showing the points with it has
               dropped significantly.  You can use the `O' command to  turn
               showexp  off  to  avoid  using  up  the  limited status line
               space.)

          Time
               The number of turns elapsed so far, displayed  if  you  have
               the time option set.

          Status
               Hunger:  your  current  hunger status.  Values are Satiated,
               Not Hungry (or Normal), Hungry,  Weak,  and  Fainting.   Not
               shown when Normal.

               Encumbrance:  an indication of how what you are carrying af-
               fects your ability to move.  Values are Unencumbered, Encum-
               bered,  Stressed,  Strained, Overtaxed, and Overloaded.  Not
               shown when Unencumbered.

               Fatal conditions: Stone (aka Petrifying, turning to  stone),
               Slime  (turning into green slime), Strngl (being strangled),
               FoodPois (suffering  from  acute  food  poisoning),  TermIll
               (suffering from a terminal illness).

               Non-fatal  conditions: Blind (can't see), Deaf (can't hear),
               Stun (stunned), Conf (confused), Hallu (hallucinating).

               Movement modifiers: Lev  (levitating),  Fly  (flying),  Ride
               (riding).

               Other conditions and modifiers exist, but there isn't enough
               room to display them with the other status fields.

          The #attributes command (default key ^X) will  show  all  current
          status  information in unabbreviated format.  It also shows other
          information which might be included on the status lines if  those
          had more room.

          3.2.  The message line (top)

               The top line of the screen is reserved for messages that de-
          scribe things that are impossible to represent visually.  If  you
          see a "--More--" on the top line, this means that NetHack has an-
          other message to display on the screen, but it wants to make cer-
          tain  that  you've read the one that is there first.  To read the
          next message, just press the space bar.

               To change how and what messages are  shown  on  the  message
          line, see "Configuring Message Types" and the verbose option.

          3.3.  The map (rest of the screen)

               The  rest  of the screen is the map of the level as you have
          explored it so far.  Each symbol on the screen  represents  some-
          thing.   You  can  set various graphics options to change some of
          the symbols the game uses; otherwise, the game will  use  default
          symbols.  Here is a list of what the default symbols mean:

          - and |
               The walls of a room, or an open door.  Or a grave (|).

          .    The floor of a room, ice, or a doorless doorway.

          #    A  corridor,  or iron bars, or a tree, or possibly a kitchen
               sink (if your dungeon has sinks), or a drawbridge.

          >    Stairs down: a way to the next level.

          <    Stairs up: a way to the previous level.

          +    A closed door, or a spellbook containing a spell you may  be
               able to learn.

          @    Your character or a human.

          $    A pile of gold.

          ^    A trap (once you have detected it).

          )    A weapon.

          [    A suit or piece of armor.

          %    Something edible (not necessarily healthy).

          ?    A scroll.

          /    A wand.

          =    A ring.

          !    A potion.

          (    A useful item (pick-axe, key, lamp...).

          "    An amulet or a spider web.

          *    A gem or rock (possibly valuable, possibly worthless).

          `    A boulder or statue.

          0    An iron ball.

          _    An altar, or an iron chain.

          {    A fountain.

          }    A pool of water or moat or a pool of lava.

          \    An opulent throne.

          a-zA-Z and other symbols
               Letters  and certain other symbols represent the various in-
               habitants of the Mazes of Menace.  Watch out,  they  can  be
               nasty and vicious.  Sometimes, however, they can be helpful.

          I    This marks the last known location of an invisible or other-
               wise unseen monster.   Note  that  the  monster  could  have
               moved.  The `F' and `m' commands may be useful here.

               You  need  not  memorize  all these symbols; you can ask the
          game what any symbol represents with the  `/'  command  (see  the
          next section for more info).

          4.  Commands

               Commands can be initiated by typing one or two characters to
          which the command is bound to, or typing the command name in  the
          extended  commands  entry.   Some commands, like "search", do not
          require that any more information be collected by NetHack.  Other
          commands  might require additional information, for example a di-
          rection, or an object to be used.  For those  commands  that  re-
          quire  additional  information, NetHack will present you with ei-
          ther a menu of choices or with a command line  prompt  requesting
          information.  Which you are presented with will depend chiefly on
          how you have set the menustyle option.

               For example, a common question, in the  form  "What  do  you
          want  to  use? [a-zA-Z ?*]", asks you to choose an object you are
          carrying.  Here, "a-zA-Z" are the inventory letters of your  pos-
          sible  choices.   Typing `?' gives you an inventory list of these
          items, so you can see what each letter refers to.  In this  exam-
          ple, there is also a `*' indicating that you may choose an object
          not on the list, if you wanted to use something unexpected.  Typ-
          ing  a  `*'  lists  your  entire  inventory,  so  you can see the


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              10



          inventory letters of every object you're carrying.   Finally,  if
          you change your mind and decide you don't want to do this command
          after all, you can press the ESC key to abort the command.

               You can put a number before some  commands  to  repeat  them
          that  many  times;  for example, "10s" will search ten times.  If
          you have the number_pad option set, you must type `n' to prefix a
          count,  so the example above would be typed "n10s" instead.  Com-
          mands for which counts make no sense ignore them.   In  addition,
          movement  commands  can  be prefixed for greater control (see be-
          low).  To cancel a count or a prefix, press the ESC key.

               The list of commands is rather long, but it can be  read  at
          any  time during the game through the `?' command, which accesses
          a menu of helpful texts.  Here are the default key  bindings  for
          your reference:

          ?    Help menu:  display one of several help texts available.

          /    The "whatis" command, to tell what a symbol represents.  You
               may choose to specify a location or type a symbol (or even a
               whole  word)  to  explain.  Specifying a location is done by
               moving the cursor to a particular spot on the map  and  then
               pressing one of `.', `,', `;', or `:'.  `.' will explain the
               symbol at the chosen location, conditionally check for "More
               info?"  depending  upon  whether  the help option is on, and
               then you will be asked to pick another  location;  `,'  will
               explain the symbol but skip any additional information, then
               let you pick another location; `;' will skip additional info
               and also not bother asking you to choose another location to
               examine; `:' will show additional info, if any, without ask-
               ing for confirmation.  When picking a location, pressing the
               ESC key will terminate this command, or  pressing  `?'  will
               give a brief reminder about how it works.

               If  the  autodescribe  option  is on, a short description of
               what you see at each location is shown as you move the  cur-
               sor.   Typing  `#' while picking a location will toggle that
               option on or off.  The whatis_coord option controls  whether
               the short description includes map coordinates.

               Specifying  a  name  rather than a location always gives any
               additional information available about that name.

               You may also request a description of nearby  monsters,  all
               monsters  currently  displayed,  nearby  objects, or all ob-
               jects.  The whatis_coord option controls which format of map
               coordinate is included with their descriptions.

          &    Tell what a command does.

          <    Go  up  to  the previous level (if you are on a staircase or
               ladder).

               Go  one  step in the direction indicated (see Figure 3).  If
               you sense or remember a monster there, you  will  fight  the
               monster  instead.   Only  these  one-step  movement commands
               cause you to fight monsters; the others (below) are "safe."

               Go in that direction until you hit a wall or run into  some-
               thing.

          m[yuhjklbn]
               Prefix:   move  without picking up objects or fighting (even
               if you remember a monster there).

               A few non-movement commands use the `m'  prefix  to  request
               operating    via   menu   (to   temporarily   override   the
               menustyle:Traditional option).   Primarily  useful  for  `,'
               (pickup)  when  there  is  only one class of objects present
               (where there won't be any "what kinds of objects?"   prompt,
               so no opportunity to answer `m' at that prompt).

               The prefix will make "#travel" command show a menu of inter-
               esting targets in sight.  It can also be used with  the  `\'
               (known,  show  a list of all discovered objects) and the ``'
               (knownclass, show a list of discovered objects in a particu-
               lar  class)  commands to offer a menu of several sorting al-
               ternatives (which sets a new value for  the  sortdiscoveries
               option).

               A  few other commands (eat food, offer sacrifice, apply tin-
               ning-kit, drink/quaff, dip)  use  the  `m'  prefix  to  skip
               checking for applicable objects on the floor and go straight
               to checking inventory, or (for "#loot" to remove a  saddle),
               skip containers and go straight to adjacent monsters.

               In  debug  mode (aka "wizard mode"), the `m' prefix may also
               be used with the "#teleport" and "#wizlevelport" commands.

          F[yuhjklbn]
               Prefix:  fight a monster (even if  you  only  guess  one  is
               there).

          g[yuhjklbn]
               Prefix:  move until something interesting is found.

          G[yuhjklbn] or <Control>+[yuhjklbn]
               Prefix:   similar  to  `g',  but forking of corridors is not
               considered interesting.

               Note:  <Control>+<key> means holding the <Control> or <Ctrl>
               key down like <Shift> while typing and releasing <key>, then
               releasing <Control>. ^<key> is used as  shorthand  elsewhere
               in the Guidebook to mean the same thing.  Control characters
               are case-insensitive so ^x and ^X are the same.

          M[yuhjklbn]
               Old versions supported `M' as a movement prefix  which  com-
               bined the effect of `m' with <Control>+<direction>.  That is
               no longer supported as a prefix but similar  effect  can  be
               achieved  by  using  `m' and G<direction> in combination.  m
               can also be used in  combination  with  g<direction>,  <Con-
               trol>+<direction>, or <Shift>+<direction>.

          _    Travel to a map location via a shortest-path algorithm.

               The  shortest  path  is computed over map locations the hero
               knows about (e.g. seen or previously traversed).   If  there
               is no known path, a guess is made instead.  Stops on most of
               the same conditions as the `G' prefix, but  without  picking
               up  objects, so implicitly forces the `m' prefix.  For ports
               with mouse support, the  command  is  also  invoked  when  a
               mouse-click takes place on a location other than the current
               position.

          .    Wait or rest, do nothing for one turn.  Precede with the `m'
               prefix to wait for a turn even next to a hostile monster, if
               safe_wait is on.

          a    Apply (use) a tool (pick-axe, key, lamp...).

               If used on a wand, that wand will be broken,  releasing  its
               magic in the process.  Confirmation is required.

          A    Remove one or more worn items, such as armor.

               Use  `T'  (take  off) to take off only one piece of armor or
               `R' (remove) to take off only one accessory.

          ^A   Repeat the previous command.

          c    Close a door.

          C    Call (name) a monster, an individual object, or  a  type  of
               object.

               Same as extended command "#name".

          ^C   Panic button.  Quit the game.

          d    Drop something.

               For example "d7a" means drop seven items of object a.

          D    Drop several things.

               In answer to the question

               "What kinds of things do you want to drop? [!%= BUCXPaium]"

               you  should  type  zero or more object symbols possibly fol-
               lowed by `a' and/or `i' and/or `u' and/or `m'.  In addition,
               one  or  more  of  the blessed/uncursed/cursed groups may be
               typed.

               DB  - drop all objects known to be blessed.
               DU  - drop all objects known to be uncursed.
               DC  - drop all objects known to be cursed.
               DX  - drop all objects of unknown B/U/C status.
               DP  - drop objects picked up last.
               Da  - drop all objects, without asking for confirmation.
               Di  - examine your inventory before dropping anything.
               Du  - drop only unpaid objects (when in a shop).
               Dm  - use a menu to pick which object(s) to drop.
               D%u - drop only unpaid food.

               The last example shows a combination.  There are four  cate-
               gories  of object filtering: class (`!' for potions, `?' for
               scrolls, and so on), shop status (`u' for unpaid,  in  other
               words, owned by the shop), bless/curse state (`B', `U', `C',
               and `X' as shown above), and novelty (`P',  recently  picked
               up items; controlled by picking up or dropping things rather
               than by any time factor).

               If you specify more than one value in a  category  (such  as
               "!?"  for  potions  and  scrolls or "BU" for blessed and un-
               cursed), an inventory object will meet the  criteria  if  it
               matches  any  of  the specified values (so "!?" means `!' or
               `?').  If you specify more than one category,  an  inventory
               object  must  meet  each  of  the category criteria (so "%u"
               means class `%' and unpaid `u').  Lastly,  you  may  specify
               multiple  values within multiple categories: "!?BU" will se-
               lect all potions and scrolls which are known to  be  blessed
               or uncursed.  (In versions prior to 3.6, filter combinations
               behaved differently.)

               Normally checks for edible item(s) on  the  floor,  then  if
               none are found or none are chosen, checks for edible item(s)
               in inventory.  Precede `e' with the `m' prefix to bypass at-
               tempting to eat anything off the floor.

               If  you  attempt  to  eat  while already satiated, you might
               choke to death.  If you risk it, you will be  asked  whether
               to  "continue  eating?"  if you survive the first bite.  You
               can set the paranoid_confirmation:eating option to require a
               response of yes instead of just y.

          E    Engrave a message on the floor.

                    E- - write in the dust with your fingers.

               Engraving  the  word  "Elbereth" will cause most monsters to
               not attack you hand-to-hand (but if you attack, you will rub
               it out); this is often useful to give yourself a breather.

          f    Fire  (shoot  or  throw)  one  of the objects placed in your
               quiver (or quiver sack, or that you have at the ready).  You
               may  select  ammunition  with a previous `Q' command, or let
               the computer pick something  appropriate  if  autoquiver  is
               true.  If your wielded weapon has the throw-and-return prop-
               erty, your quiver is empty, and  autoquiver  is  false,  you
               will  throw  that  wielded  weapon  instead  of  filling the
               quiver.  This will  also  automatically  use  a  polearm  if
               wielded.   If  fireassist is true, firing will automatically
               try to wield a launcher (for example,  a  bow  or  a  sling)
               matching  the  ammo  in the quiver; this might take multiple
               turns, and get interrupted by a monster.  Remember  to  swap
               back to your main melee weapon afterwards.

               See also `t' (throw) for more general throwing and shooting.

          i    List your inventory (everything you're carrying).

          I    List selected parts of your inventory, usually be specifying
               the character for a particular set of objects, like `['  for
               armor or `!' for potions.

               I* - list all gems in inventory;
               Iu - list all unpaid items;
               Ix - list all used up items that are on your shopping bill;
               IB - list all items known to be blessed;
               IU - list all items known to be uncursed;
               IC - list all items known to be cursed;
               IX - list all items whose bless/curse status is unknown;

          O    Set options.

               A  menu showing the current option values will be displayed.
               You can change most values simply by selecting the menu  en-
               try for the given option (ie, by typing its letter or click-
               ing upon it, depending on your  user  interface).   For  the
               non-boolean  choices,  a  further menu or prompt will appear
               once you've closed this menu.   The  available  options  are
               listed later in this Guidebook.  Options are usually set be-
               fore the game rather than with the `O' command; see the sec-
               tion  on  options below.  Precede `O' with the `m' prefix to
               show advanced options.

          ^O   Show overview.

               Shortcut for "#overview":  list interesting  dungeon  levels
               visited.

               (Prior  to 3.6.0, `^O' was a debug mode command which listed
               the placement of all special levels.  Use "#wizwhere" to run
               that command.)

          p    Pay your shopping bill.

          P    Put on an accessory (ring, amulet, or blindfold).

               This command may also be used to wear armor.  The prompt for
               which inventory item to use will only list accessories,  but
               choosing  an unlisted item of armor will attempt to wear it.
               (See the `W' command below.  It lists armor as the inventory
               choices but will accept an accessory and attempt to put that
               on.)

          ^P   Repeat previous message.

               Subsequent `^P's repeat earlier messages.  For  some  inter-
               faces, the behavior can be varied via the msg_window option.

          q    Quaff (drink) something (potion, water, etc).

               When there is a fountain or sink present, it asks whether to
               drink from that.  If that is  declined,  then  it  offers  a
               chance  to choose a potion from inventory.  Precede `q' with
               the `m' prefix to skip asking about drinking from a fountain
               or sink.

          Q    Select  an object for your quiver, quiver sack, or just gen-
               erally at the ready (only one of these  is  available  at  a
               time).   You can then throw this (or one of these) using the
               `f' command.

          r    Read a scroll or spellbook.

          R    Remove a worn accessory (ring, amulet, or blindfold).

               If you're wearing more than  one,  you'll  be  prompted  for
               which  one to remove.  When you're only wearing one, then by
               default it will be removed without asking, but you  can  set
               the paranoid_confirmation option to require a prompt.

               This command may also be used to take off armor.  The prompt
               for which inventory item to remove only  lists  worn  acces-
               sories,  but  an item of worn armor can be chosen.  (See the
               `T' command below.  It lists armor as the inventory  choices
               but will accept an accessory and attempt to remove it.)

          ^R   Redraw the screen.

          s    Search  for  secret  doors and traps around you.  It usually
               takes several tries to find something.  Precede with the `m'
               prefix  to search for a turn even next to a hostile monster,
               if safe_wait is on.

               Can also be used to figure out whether there is still a mon-
               ster at an adjacent "remembered, unseen monster" marker.

          S    Save  the  game (which suspends play and exits the program).
               The saved game will be restored automatically the next  time
               you play using the same character name.

               In  normal play, once a saved game is restored the file used
               to hold the saved data is deleted.  In  explore  mode,  once
               restoration is accomplished you are asked whether to keep or
               delete the file.  Keeping the file makes it feasible to play
               for  a  while  then  quit  without  saving and later restore
               again.

               There is no "save current game state and keep playing"  com-
               mand, not even in explore mode where saved game files can be
               kept and re-used.

          t    Throw an object or shoot a projectile.

               There's no separate "shoot" command.  If you throw an  arrow
               while  wielding  a  bow, you are shooting that arrow and any
               weapon skill bonus or penalty for bow applies.  If you throw
               an  arrow  while  not wielding a bow, you are throwing it by
               hand and it will generally be less effective than when shot.

               See also `f' (fire) for throwing or shooting an item pre-se-
               lected via the `Q' (quiver) command, with some extra assist-
               ance.

          T    Take off armor.

               If you're wearing more than one piece,  you'll  be  prompted
               for  which  one to take off.  (Note that this treats a cloak

               covering a suit and/or a shirt, or a suit covering a  shirt,
               as if the underlying items weren't there.)  When you're only
               wearing one, then by default it will be  taken  off  without
               asking,  but you can set the paranoid_confirmation option to
               require a prompt.

               This command may also be used to  remove  accessories.   The
               prompt  for which inventory item to take off only lists worn
               armor, but a worn accessory can be  chosen.   (See  the  `R'
               command above.  It lists accessories as the inventory choic-
               es but will accept an item of armor and attempt to  take  it
               off.)

               Some  characters  can wield two weapons at once; use the `X'
               command (or the "#twoweapon" extended command) to do so.

          W    Wear armor.

               This command may also be used to put on an accessory  (ring,
               amulet,  or blindfold).  The prompt for which inventory item
               to use will only list armor, but choosing an unlisted acces-
               sory will attempt to put it on.  (See the `P' command above.
               It lists accessories as the inventory choices but  will  ac-
               cept an item of armor and attempt to wear it.)

          x    Exchange your wielded weapon with the item in your alternate
               weapon slot.

               The latter is used as your secondary weapon when engaging in
               two-weapon  combat.  Note that if one of these slots is emp-
               ty, the exchange still takes place.

          +    List the spells you know.

               Using this command, you can  also  rearrange  the  order  in
               which  your  spells are listed, either by sorting the entire
               list or by picking one spell from the menu then picking  an-
               other  to  swap  places  with  it.  Swapping pairs of spells
               changes their casting letters, so the change lasts after the

               and then  pick  "reassign  casting  letters".   (Any  spells
               learned  after  that  will  be  added to the end of the list

               As  you can see, the authors of NetHack used up all the let-
          ters, so this is a way to introduce the less frequently used com-
          mands.  What extended commands are available depends on what fea-
          tures the game was compiled with.

          #adjust
               Adjust inventory letters (most useful when the fixinv option
               is "on").  Autocompletes.  Default key is `M-a'.

               This  command allows you to move an item from one particular
               inventory slot to another so that it has a letter  which  is
               more meaningful for you or that it will appear in a particu-
               lar location when inventory listings are displayed.  You can
               move to a currently empty slot, or if the destination is oc-
               cupied--and won't merge--the item there will swap slots with
               the  one being moved.  "#adjust" can also be used to split a
               stack of objects; when choosing the item to adjust, enter  a
               count prior to its letter.

               Adjusting  without  a  count  used to collect all compatible
               stacks when moving to the destination.   That  behavior  has
               been changed; to gather compatible stacks, "#adjust" a stack
               into its own inventory slot.  If it  has  a  name  assigned,
               other  stacks  with the same name or with no name will merge
               provided that all their other attributes match.  If it  does
               not  have  a name, only other stacks with no name are eligi-
               ble.  In either case, otherwise  compatible  stacks  with  a
               different  name will not be merged.  This contrasts with us-
               ing "#adjust" to move from one slot to a different slot.  In
               that  situation,  moving (no count given) a compatible stack
               will merge if either stack has a name when the other doesn't
               and  give  that  name  to the result, while splitting (count
               given) will ignore the source  stack's  name  when  deciding
               whether to merge with the destination stack.

          #annotate
               Allows you to specify one line of text to associate with the
               current dungeon level.  All levels with annotations are dis-
               played  by the "#overview" command.  Autocompletes.  Default

               If  the  tool used acts on items on the floor, using the `m'
               prefix skips those items.

               If used on a wand, that wand will be broken,  releasing  its
               magic in the process.  Confirmation is required.

               cede with the `m' prefix to execute the simpler options com-
               mand.   (Mainly  useful  if you use BINDING=O:optionsfull to
               switch `O' from simple options back to traditional  advanced
               options.)

          #overview
               Display  information  you've  discovered  about the dungeon.
               Any visited level (unless forgotten due to amnesia) with  an
               annotation  is  included,  and many things (altars, thrones,
               fountains, and so on; extra stairs leading to  another  dun-
               geon  branch)  trigger  an automatic annotation.  If dungeon
               overview is chosen during end-of-game disclosure, every vis-

          #perminv
               If persistent inventory display  is  supported  and  enabled
               (with  the  perm_invent option), interact with it instead of
               with the map.  You'll be prompted for  menu  scrolling  key-
               strokes  such as `>' and `<'.  Press Return or Escape to re-

               Pray  to  the gods for help.  Autocompletes.  Default key is
               `M-p'.

               Praying too soon after receiving prior help is a  bad  idea.
               (Hint:  entering  the dungeon alive is treated as having re-
               ceived help.  You probably shouldn't start off a new game by
               praying  right  away.)  Since using this command by accident
               can cause trouble, there is an option to  make  you  confirm
               your  intent  before praying.  It is enabled by default, and
               you can reset the paranoid_confirmation  option  to  disable
               it.

               `P'.

          #quaff
               Quaff (drink) something.  Default key is `q'.

               The  `m'  prefix  skips  drinking from a fountain or sink if
               there is one at your location.

          #quit
               Quit the program without saving your game.  Autocompletes.

               Since using this command by accident would  throw  away  the
               current  game,  you  are asked to confirm your intent before
               quitting.  Default response is n (no); continue playing.  To
               really  quit, respond with y.  You can set the paranoid_con-
               firmation:quit option to require a response of yes instead.

          #quiver
               Select ammunition for quiver.  Default key is `Q'.

          #read
               Read a scroll, a spellbook, or something else.  Default  key

               number_pad is on.

               Remove an accessory (ring, amulet,  etc).   Default  key  is
               `R'.

          #repeat
               Repeat the previous command.  Default key is `^A'.

          #rush
               Prefix key to rush towards a direction.  Default is `g' when
               number_pad  is  off, `M-5' when number_pad is set to 1 or 3,
               otherwise `5' when it is set to 2 or 4.

               was started from without performing save-and-exit.   Can  be
               disabled  at  the  time the program is built.  When enabled,
               mainly useful for tty and curses interfaces  on  UNIX.   Use
               the  shell  command `fg' to return to the game.  Default key

               In  explore mode, you can choose to view the full map rather
               than just its explored portion.  In debug mode there are ad-
               ditional choices.

               Autocompletes.   Default  key  is `<del>' or `<delete>' (see
               Del above).

          #therecmdmenu
               Show a menu of possible actions directed at a location  next
               to  you.   The  menu is limited to a subset of the likeliest
               actions, not an exhaustive set of all possibilities.   Auto-
               completes.

          #throw
               Throw something.  Default key is `t'.

          #tip
               Tip  over a container (bag or box) to pour out its contents.
               Autocompletes.  Default key is `M-T'.  The `m' prefix  makes
               the command use a menu.

          #travel
               Travel  to  a  specific location on the map.  Default key is
               `_'.  Using the "request menu" prefix shows a menu of inter-
               esting  targets  in sight without asking to move the cursor.
               When picking a target with cursor and the  autodescribe  op-
               tion  is  on,  the  top line will show "(no travel path)" if
               your character does not know of a  path  to  that  location.
               See also #retravel.

          #turn
               Turn undead away.  Autocompletes.  Default key is `M-t'.

          #twoweapon
               Toggle two-weapon combat on or off.  Autocompletes.  Default
               key is `X', and also `M-2' if number_pad is off.

               Note that you must use suitable weapons  for  this  type  of
               combat, or it will be automatically turned off.

          #untrap
               Untrap something (trap, door, or chest).  Default key is `M-
               u', and `u' if number_pad is on.

               In some circumstances it can also be used to rescue  trapped
               monsters.

          #up
               Go up a staircase.  Default key is `<'.

          #vanquished
               List vanquished monsters by type and count.

               Note that the vanquished monsters list includes all monsters
               killed by traps and each other as well as by you, and  omits
               any  which  got  removed  from the game without being killed
               (perhaps by genocide, or by a mollified shopkeeper  dismiss-
               ing  summoned  Kops)  or were already corpses when placed on
               the map.

               Using the "request menu" prefix prior to #vanquished  brings
               up  a  menu  of  sorting orders available (provided that the
               vanquished monsters list contains at least two types of mon-
               sters).   Whichever  ordering is picked gets assigned to the
               sortvanquished option so is remembered for subsequent  #van-
               quished requests.  During end-of-game disclosure, when asked
               whether to show vanquished monsters answering `a'  will  let
               you choose from the sort menu.

               The  second  paragraph  lists the user interface(s) that are
               included.  If there are more than one, you can use the  win-
               dowtype option in your run-time configuration file to select
               the one you want.

               Autocompletes.  Default key is `M-v'.

          #versionshort
               Show the program's version number, plus the  date  and  time
               that  the  running copy was built from sources (not the ver-
               sion's release date).  Default key is `v'.

               Show vision array.  Autocompletes.  Debug mode only.

          #wait
               Rest one move while doing nothing.  Default key is `.',  and
               also ` ' if rest_on_space is on.

          #wear
               Wear a piece of armor.  Default key is `W'.

          #whatdoes
               Tell what a key does.  Default key is `&'.

          #whatis
               Show  what  type  of thing a symbol corresponds to.  Default
               key is `/'.

               If your keyboard has a meta key (which, when pressed in com-
          bination  with  another  key,  modifies  it by setting the "meta"
          [8th, or "high"] bit), you can invoke many extended  commands  by
          meta-ing the first letter of the command.

               On  Windows  and  MS-DOS,  the "Alt" key can be used in this
          fashion.  On other systems, if  typing  "Alt"  plus  another  key
          transmits  a  two character sequence consisting of an Escape fol-
          lowed by the other key, you may set the altmeta  option  to  have
          NetHack combine them into meta+<key>.  (This combining action on-
          ly takes place when NetHack is expecting a  command  to  execute,
          not when accepting input to name something or to make a wish.)

               Unlike  control  characters, where ^x and ^X denote the same
          thing, meta characters are case-sensitive:  M-x and M-X represent
          different  things.   Some  commands  which  can be run via a meta
          character require that the letter be capitalized because the low-
          er-case  equivalent is used for another command, so the three key
          combination meta+Shift+<letter> is needed.

          5.  Rooms and corridors

               Rooms  and  corridors in the dungeon are either lit or dark.
          Any lit areas within your line of sight will be  displayed;  dark
          areas  are  only  displayed  if they are within one space of you.
          Walls and corridors remain on the map as you explore them.

               Secret corridors are hidden and appear  to  be  solid  rock.
          You  can find them with the `s' (search) command when adjacent to
          them.  Multiple search attempts may be needed.  When searching is
          successful,  secret corridors become ordinary open corridor loca-
          tions.  Mapping magic reveals secret corridors, so converts  them
          into ordinary corridors and shows them as such.

          5.1.  Doorways

               Doorways connect rooms and corridors.  Some doorways have no
          doors; you can walk right through.  Others have  doors  in  them,
          which may be open, closed, or locked.  To open a closed door, use
          the `o' (open) command; to close it again, use  the  `c'  (close)
          command.   By  default  the autoopen option is enabled, so simply
          attempting to walk onto a closed door's location will attempt  to
          open  it without needing `o'.  Opening via autoopen will not work
          if you are confused or stunned or suffer from the fumbling attri-
          bute.

               Open  doors  cannot be entered diagonally; you must approach
          them straight on, horizontally or vertically.   Doorways  without
          doors are not restricted in this fashion except on one particular
          level (described by "#overview" as "a primitive area").

               Unlocking magic exists but usually won't be available  early
          on.  You can get through a locked door without magic by first us-
          ing an unlocking tool with the  `a'  (apply)  command,  and  then
          opening it.  By default the autounlock option is also enabled, so
          if you attempt to open (via `o' or autoopen) a locked door  while
          carrying  an unlocking tool, you'll be asked whether to use it on
          the door's lock.  Alternatively, you  can  break  a  closed  door


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              34



          (whether  locked  or  not) down by kicking it via the `^D' (kick)
          command.  Kicking down a door destroys it  and  makes  a  lot  of
          noise which might wake sleeping monsters.

               Some  closed  doors are booby-trapped and will explode if an
          attempt is made to open (when unlocked) or unlock  (when  locked)
          or  kick  down.  Like kicking, an explosion destroys the door and
          makes a lot of noise.  The  "#untrap"  command  can  be  used  to
          search  a door for traps but might take multiple attempts to find
          one.  When one is found, you'll be asked whether to try to disarm
          it.   If  you accede, success will eliminate the trap but failure
          will set off the trap's explosion.  (If you decline,  you  effec-
          tively forget that a trap was found there.)

               Closed  doors can be useful for shutting out monsters.  Most
          monsters cannot open closed doors, although a few don't  need  to
          (for  example,  ghosts  can walk through doors and fog clouds can
          flow under them).  Some monsters who can open doors can also  use
          unlocking tools.  And some (giants) can smash doors.

               Secret doors are hidden and appear to be ordinary wall (from
          inside a room) or solid rock (from outside).  You can  find  them
          with  the  `s'  (search) command but it might take multiple tries
          (possibly many tries if your luck is poor).  Once found they  are
          in  all  ways equivalent to normal doors.  Mapping magic does not
          reveal secret doors.

          5.2.  Traps (`^')

               There are traps throughout the dungeon to snare  the  unwary
          intruder.   For  example, you may suddenly fall into a pit and be
          stuck for a few turns trying to climb out (see  below).   A  trap
          usually  won't  appear on your map until you trigger it by moving
          onto it, you see someone else trigger it, or you discover it with
          the  `s' (search) command (multiple attempts are often needed; if
          your luck is poor, many attempts might be needed).  Wands of  se-
          cret  door detection and spell of detect unseen also reveal traps
          within a modest radius but only if the trap is also within  line-
          of-sight (whether you can see at the time or not).  There is also
          other magic which can reveal traps.

               Monsters can fall prey to traps, too, which can  potentially
          be  used  as  a  defensive  strategy.  Unfortunately traps can be
          harmful to your pet(s) as well.  Monsters, including pets, usual-
          ly  will  avoid  moving onto a trap which is shown on your map if
          they have encountered that type of trap before.

               Some traps such as pits, bear traps, and webs  hold  you  in
          one  place.   You can escape by simply trying to move to an adja-
          cent spot and repeat as needed; eventually you will get free.

               Other traps can send  you  to  different  locations.   Tele-
          porters  send  you  elsewhere  on  the same dungeon level.  Level
          teleporters send you to a random dungeon level,  the  destination


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              35



          chosen  from  a  few  levels lower all the way to the top.  These
          traps choose a new destination each time they're activated.  Trap
          doors  and holes also send you to another level, but one which is
          always below the current level.  Usually that will  be  the  next
          level  down  but  it can be farther.  Unlike (level) teleporters,
          the destination level of a particular trap door or hole  is  per-
          sistent,  so  falling  into  one will bring you to the same level
          each time--though not necessarily the same  spot  on  the  level.
          Magic  portals  behave similarly, but with some additional varia-
          tion.  Some portals are two-way and their remote  destination  is
          always  the same: another portal which can take you back.  Others
          are one-way and send you to a specific destination level but  not
          necessarily to a specific location there.

               There  is  a  special multi-level branch of the dungeon with
          pre-mapped levels based on the classic computer  game  "Sokoban."
          In that game, you operate as a warehouse worker who pushes crates
          around obstacles to position them at  designated  locations.   In
          NetHack,  the  goal  is to push boulders into pits or holes until
          those traps have all been nullified, giving access to whatever is
          beyond  them.  In the Sokoban game, you can only move in the four
          cardinal compass directions, and a crate in its final destination
          blocks  further  access  to  that spot.  In the Sokoban levels of
          NetHack, you can move diagonally (unless that would let you  pass
          between  two neighboring boulders) but you can only push boulders
          in the four cardinal directions, and a boulder which fills a  pit
          or  hole removes both the boulder and the trap so opens up normal
          access to that spot.  With careful foresight, it is  possible  to
          complete  all of the levels according to the traditional rules of
          Sokoban.  (Hint: to solve Sokoban puzzles, you often need to move
          things  away from their eventual destinations in order to open up
          more room to maneuver.)  Since NetHack does not support  an  undo
          capability,  some allowances are permitted in case you get stuck.
          For example, each level has at least one extra boulder.  Also, it
          is possible to drop everything in order to be able to squeeze in-
          to the same location as a boulder (and then presumably move  past
          it),  or  to  destroy a boulder with magic or tools, or to create
          new boulders with a scroll of earth.  However, doing such  things
          will  lower  your  luck  without any specific message given about
          that.  See the Conduct  section  for  information  about  getting
          feedback for your actions in Sokoban.

          5.3.  Stairs and ladders (`<', `>')

               In  general, each level in the dungeon will have a staircase
          going up (`<') to the previous level and another going down (`>')
          to  the  next  level.  There are some exceptions though.  For in-
          stance, fairly early in the dungeon you will find  a  level  with
          two down staircases, one continuing into the dungeon and the oth-
          er branching into an area known  as  the  Gnomish  Mines.   Those
          mines  eventually hit a dead end, so after exploring them (if you
          choose to do so), you'll need to climb back up to the  main  dun-
          geon.



          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              36



               When  you  traverse a set of stairs, or trigger a trap which
          sends you to another level, the level you're leaving will be  de-
          activated  and  stored  in a file on disk.  If you're moving to a
          previously visited level, it will be loaded from its file on disk
          and  reactivated.   If you're moving to a level which has not yet
          been visited, it will be created (from scratch  for  most  random
          levels, from a template for some "special" levels, or loaded from
          the remains of an earlier game for a "bones" level as briefly de-
          scribed  below).   Monsters are only active on the current level;
          those on other levels are essentially placed into stasis.

               Ordinarily when you climb a set of stairs, you  will  arrive
          on  the  corresponding  staircase  at your destination.  However,
          pets (see below) and some other monsters  will  follow  along  if
          they're close enough when you travel up or down stairs, and occa-
          sionally one of these creatures  will  displace  you  during  the
          climb.  When that occurs, the pet or other monster will arrive on
          the staircase and you will end up nearby.

               Ladders serve the same purpose as staircases,  and  the  two
          types  of  inter-level  connections  are nearly indistinguishable
          during game play.

          5.4.  Shops and shopping

               Occasionally you will run across a room  with  a  shopkeeper
          near  the  door  and  many items lying on the floor.  You can buy
          items by picking them up and then using the `p' command.  You can
          inquire  about the price of an item prior to picking it up by us-
          ing the "#chat" command while standing on it.  Using an item pri-
          or to paying for it will incur a charge, and the shopkeeper won't
          allow you to leave the shop until you have paid any debt you owe.

               You can sell items to a shopkeeper by dropping them  to  the
          floor  while inside a shop.  You will either be offered an amount
          of gold and asked whether you're willing to sell,  or  you'll  be
          told  that  the shopkeeper isn't interested (generally, your item
          needs to be compatible with the type of  merchandise  carried  by
          the shop).

               If  you drop something in a shop by accident, the shopkeeper
          will usually claim ownership without offering  any  compensation.
          You'll have to buy it back if you want to reclaim it.

               Shopkeepers  sometime  run out of money.  When that happens,
          you'll be offered credit instead of gold when  you  try  to  sell
          something.   Credit  can  be used to pay for purchases, but it is
          only good in the shop where it was  obtained;  other  shopkeepers
          won't  honor  it.   (If you happen to find a "credit card" in the
          dungeon, don't bother trying to use it in shops; shopkeepers will
          not accept it.)

               The  `$'  command,  which reports the amount of gold you are
          carrying, will also show current shop debt  or  credit,  if  any.


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              37



          The  "Iu" command lists unpaid items (those which still belong to
          the shop) if you are carrying any.  The "Ix" command shows an in-
          ventory-like display of any unpaid items which have been used up,
          along with other shop fees, if any.

          5.4.1.  Shop idiosyncrasies

               Several aspects of shop behavior might be unexpected.

          * The price of a given item can vary due to a variety of factors.

          * A shopkeeper treats the spot immediately inside the door as  if
            it were outside the shop.

          * While  the  shopkeeper  watches you like a hawk, he or she will
            generally ignore any other customers.

          * If a shop is "closed for inventory," it will not  open  of  its
            own accord.

          * Shops do not get restocked with new items, regardless of inven-
            tory depletion.

          5.5.  Movement feedback

               Moving around the map usually  provides  no  feedback--other
          than  drawing the hero at the new location--unless you step on an
          object or pile of objects, or on a trap, or attempt to move  onto
          a  spot  where  a  monster is located.  There are several options
          which can be used to augment the normal feedback.

               The pile_limit option controls how many objects can be in  a
          pile--sharing the same map location--for the game to state "there
          are objects here" instead of listing them.   The  default  is  5.
          Setting it to 1 would always give that message instead of listing
          any objects.  Setting it to 0 is a special case which will always
          list all objects no matter how big a pile is.  Note that the num-
          ber refers to the count of separate  stacks  of  objects  present
          rather  than  the sum of the quantities of those stacks (so 7 ar-
          rows or 25 gold pieces will each count as 1 rather than as 7  and
          25,  respectively, and total to 2 when both are at the same loca-
          tion).

               The "nopickup" command prefix (default `m') can be used  be-
          fore  a  movement direction to step on objects without attempting
          auto-pickup and without giving feedback about them.

               The mention_walls option controls whether you  get  feedback
          if  you try to walk into a wall or solid stone or off the edge of
          the map.  Normally nothing happens (unless the hero is blind  and
          no wall is shown, then the wall that is being bumped into will be
          drawn on the map).  This option also gives feedback when  rushing
          or running stops for some non-obvious reason.



          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              38



               The  mention_decor  option controls whether you get feedback
          when walking on "furniture."  Normally stepping onto stairs or  a
          fountain  or an altar or various other things doesn't elicit any-
          thing unless it is covered by one or more objects so is  obscured
          on  the  map.   Setting  this  option  to true will describe such
          things even when they aren't  obscured.   Doorless  doorways  and
          open  doors aren't considered worthy of mention; closed doors (if
          you can move onto their spots) and broken  doors  are.   Assuming
          that  you're able to do so, moving onto water or lava or ice will
          give feedback if not yet on that type of terrain but  not  repeat
          it  (unless  there has been some intervening message) when moving
          from water to another water spot, or lava to lava, or ice to ice.
          Moving  off  of any of those back onto "normal" terrain will give
          one message too, unless there is feedback about one or  more  ob-
          jects, in which case the back on land circumstance is implied.

               The  confirm  and safe_pet options control what happens when
          you try to move onto a peaceful monster's spot or  a  tame  one's
          spot.

               The  "nopickup"  command  prefix  (default  `m') is also the
          move-without-attacking prefix and can be used to try to step onto
          a visible monster's spot without the move being considered an at-
          tack (see  the  Fighting  subsection  of  Monsters  below).   The
          "fight"  command  prefix  (default `F'; also `-' if number_pad is
          on) can be used to force an attack, when guessing where an unseen
          monster  is  or  when  deliberately  attacking a peaceful or tame
          creature.

               The run_mode option controls how frequently the map gets re-
          drawn when moving more than one step in a single command (so when
          rushing, running, or traveling).

          5.6.  Rogue level

               One dungeon level (occurring in mid to  late  teens  of  the
          main  dungeon)  is a tribute to the ancestor game hack's inspira-
          tion rogue.

               It is usually displayed differently from other levels:  pos-
          sibly  in  characters  instead  of tiles, or without line-drawing
          symbols if already in characters; also, gold is shown as * rather
          than  $ and stairs are shown as % rather than < and >.  There are
          some minor differences in actual game play: doorways lack  doors;
          a  scroll,  wand,  or spell of light used in a room lights up the
          whole room rather than within a  radius  around  your  character.
          And  monsters  represented  by lower-case letters aren't randomly
          generated on the rogue level.

               The slight strangeness of this level is  a  feature,  not  a
          bug....

          6.  Monsters

               Monsters  you  cannot  see  are not displayed on the screen.
          Beware!  You may suddenly come upon one in a  dark  place.   Some
          magic  items  can  help  you  locate  them before they locate you
          (which some monsters can do very well).

               The commands `/' and `;' may be used to  obtain  information
          about  those  monsters who are displayed on the screen.  The com-
          mand "#name" (by default bound to `C'), allows you  to  assign  a
          name  to  a  monster, which may be useful to help distinguish one
          from another when multiple monsters  are  present.   Assigning  a
          name which is just a space will remove any prior name.

               The extended command "#chat" can be used to interact with an
          adjacent monster.  There is no actual dialog (in other words, you
          don't get to choose what you'll say), but chatting with some mon-
          sters such as a shopkeeper or the Oracle of  Delphi  can  produce
          useful results.

          6.1.  Fighting

               If  you see a monster and you wish to fight it, just attempt
          to walk into it.  Many monsters you  find  will  mind  their  own
          business unless you attack them.  Some of them are very dangerous
          when angered.  Remember:  discretion is the better part of valor.

               In most circumstances, if you attempt to attack  a  peaceful
          monster  by  moving into its location, you'll be asked to confirm
          your intent.  By default an answer of `y' acknowledges  that  in-
          tent,  which can be error prone if you're using `y' to move.  You
          can set the paranoid_confirmation option to require a response of
          "yes" instead.

               If  you  can't  see a monster (if it is invisible, or if you
          are blinded), the symbol `I' will be shown when you learn of  its
          presence.   If you attempt to walk into it, you will try to fight
          it just like a monster that you can see; of course, if  the  mon-
          ster has moved, you will attack empty air.  If you guess that the
          monster has moved and you don't wish to fight, you  can  use  the
          `m'  command to move without fighting; likewise, if you don't re-
          member a monster but want to try fighting anyway, you can use the
          `F' command.

          6.2.  Your pet

               You start the game with a little dog (`d'), kitten (`f'), or
          pony (`u'), which follows you about the dungeon and  fights  mon-
          sters  with you.  Like you, your pet needs food to survive.  Dogs
          and cats usually feed  themselves  on  fresh  carrion  and  other
          meats;  horses  need  vegetarian food which is harder to come by.
          If you're worried about your pet or want to  train  it,  you  can
          feed it, too, by throwing it food.  A properly trained pet can be
          very useful under certain circumstances.


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              40



               Your pet also gains experience from  killing  monsters,  and
          can  grow  over  time,  gaining hit points and doing more damage.
          Initially, your pet may even be better  at  killing  things  than
          you, which makes pets useful for low-level characters.

               Your  pet  will  follow  you up and down staircases if it is
          next to you when you move.  Otherwise your pet will  be  stranded
          and  may  become wild.  Similarly, when you trigger certain types
          of traps which alter your location (for  instance,  a  trap  door
          which  drops you to a lower dungeon level), any adjacent pet will
          accompany you and any non-adjacent pet will be left behind.  Your
          pet  may trigger such traps itself; you will not be carried along
          with it even if adjacent at the time.

          6.3.  Steeds

               Some types of creatures in the dungeon can actually be  rid-
          den if you have the right equipment and skill.  Convincing a wild
          beast to let you saddle it up is  difficult  to  say  the  least.
          Many  a dungeoneer has had to resort to magic and wizardry in or-
          der to forge the alliance.  Once you do have the beast under your
          control  however,  you  can easily climb in and out of the saddle
          with the "#ride" command.  Lead the beast around the dungeon when
          riding, in the same manner as you would move yourself.  It is the
          beast that you will see displayed on the map.

               Riding skill is managed by the "#enhance" command.  See  the
          section on Weapon proficiency for more information about that.

               Use the `a' (apply) command and pick a saddle in your inven-
          tory to attempt to put that saddle on an adjacent  creature.   If
          successful, it will be transferred to that creature's inventory.

               Use the "#loot" command while adjacent to a saddled creature
          to try to remove the saddle from that creature.   If  successful,
          it will be transferred to your inventory.

          6.4.  Bones levels

               You  may encounter the shades and corpses of other adventur-
          ers (or even former incarnations of yourself!) and their personal
          effects.   Ghosts  are  hard  to  kill,  but easy to avoid, since
          they're slow and do little damage.  You can plunder the  deceased
          adventurer's  possessions; however, they are likely to be cursed.
          Beware of whatever killed the former player; it is probably still
          lurking around, gloating over its last victory.

          6.5.  Persistence of Monsters

               Monsters (a generic reference which also includes humans and
          pets) are only shown while they can be seen or otherwise  sensed.
          Moving  to  a location where you can't see or sense a monster any
          more will result in it disappearing from your map,  similarly  if
          it is the one who moved rather than you.


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              41



               However,  if  you encounter a monster which you can't see or
          sense--perhaps it is invisible and has just  tapped  you  on  the
          noggin--a  special  "remembered,  unseen  monster" marker will be
          displayed at the location where you think it is.  That will  per-
          sist  until  you have proven that there is no monster there, even
          if the unseen monster moves to another location or you move to  a
          spot  where the marker's location ordinarily wouldn't be seen any

          7.  Objects

               When you find something in the dungeon, it is common to want
          to pick it up.  In NetHack, this is accomplished by using the `,'
          command.  If autopickup option is on, you will automatically pick
          up  the object by walking over, unless you move with the `m' pre-
          fix.

               If you're carrying too many items, NetHack will tell you  so
          and  you  won't  be able to pick up anything more.  Otherwise, it
          will add the object(s) to your pack and tell you  what  you  just
          picked up.

               As  you add items to your inventory, you also add the weight
          of that object to your load.  The amount that you can  carry  de-
          pends  on  your strength and your constitution.  The stronger and
          sturdier you are, the less the additional load will  affect  you.
          There comes a point, though, when the weight of all of that stuff
          you are carrying around with you through the dungeon will  encum-
          ber you.  Your reactions will get slower and you'll burn calories
          faster, requiring food more frequently to cope with it.   Eventu-
          ally,  you'll be so overloaded that you'll either have to discard
          some of what you're carrying or collapse under its weight.

               NetHack will tell you how badly you  have  loaded  yourself.
          If  you are encumbered, one of the conditions Burdened, Stressed,
          Strained, Overtaxed, or Overloaded will be shown  on  the  bottom
          line status display.

               When you pick up an object, it is assigned an inventory let-
          ter.  Many commands that operate on objects must ask you to  find
          out  which  object  you  want  to  use.  When NetHack asks you to
          choose a particular object you are carrying, you are usually pre-
          sented  with a list of inventory letters to choose from (see Com-
          mands, above).

               Some objects, such as weapons,  are  easily  differentiated.
          Others,  like  scrolls  and potions, are given descriptions which
          vary according to type.  During a game, any two objects with  the
          same  description  are  the same type.  However, the descriptions
          will vary from game to game.

               When you use one of these objects, if its effect is obvious,
          NetHack  will  remember  what it is for you.  If its effect isn't
          extremely obvious, you will be asked what you want to  call  this


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              42



          type  of object so you will recognize it later.  You can also use
          the "#name" command, for the same purpose at any  time,  to  name
          all  objects  of  a particular type or just an individual object.
          When you use "#name" on an object which has already  been  named,
          specifying  a  space  as the value will remove the prior name in-
          stead of assigning a new one.

          7.1.  Curses and Blessings

               Any object that you find may be cursed, even if  the  object
          is otherwise helpful.  The most common effect of a curse is being
          stuck with (and to) the item.  Cursed weapons weld themselves  to
          your  hand  when wielded, so you cannot unwield them.  Any cursed
          item you wear is not removable by ordinary means.   In  addition,
          cursed  arms and armor usually, but not always, bear negative en-
          chantments that make them less effective in combat.  Other cursed
          objects may act poorly or detrimentally in other ways.

               Objects  can also be blessed instead.  Blessed items usually
          work better or more beneficially than normal uncursed items.  For
          example,  a  blessed  weapon will do slightly more damage against
          demons.

               Objects which are neither cursed nor blessed are referred to
          as  uncursed.   They  could just as easily have been described as
          unblessed, but the uncursed designation  is  what  you  will  see
          within  the  game.   A  "glass half full versus glass half empty"
          situation; make of that what you will.

               There are magical means of bestowing or removing curses upon
          objects,  so  even  if you are stuck with one, you can still have
          the curse lifted and the item removed.  Priests  and  Priestesses
          have  an  innate  sensitivity  to this property in any object, so
          they can more easily avoid cursed objects  than  other  character
          roles.  Dropping objects onto an altar will reveal their bless or
          curse state provided that you can see them land.

               An item with unknown status will be reported in your  inven-
          tory with no prefix.  An item which you know the state of will be
          distinguished in your inventory  by  the  presence  of  the  word
          cursed,  uncursed, or blessed in the description of the item.  In
          some cases uncursed will  be  omitted  as  being  redundant  when
          enough other information is displayed.  The implicit_uncursed op-
          tion can be used to control this; toggle it off to have  uncursed
          be displayed even when that can be deduced from other attributes.

               Sometimes the bless or curse state of objects is referred to
          as their "BUC" attribute, for Blessed, Uncursed, or Cursed state,
          or  "BUCX"  for Blessed, Uncursed, Cursed, or unknown.  (The term
          beatitude is occasionally used as well.)

          7.2.  Weapons (`)')

               Given a chance, most monsters in the Mazes  of  Menace  will
          gratuitously  try to kill you.  You need weapons for self-defense
          (killing them first).  Without a weapon,  you  do  only  1-2  hit
          points  of damage (plus bonuses, if any).  Monk characters are an
          exception; they normally do more damage  with  bare  (or  gloved)
          hands than they do with weapons.

               There are wielded weapons, like maces and swords, and thrown
          weapons, like arrows and spears.  To hit monsters with a  weapon,
          you  must wield it and attack them, or throw it at them.  You can
          simply elect to throw a spear.  To shoot  an  arrow,  you  should
          first  wield a bow, then throw the arrow.  Crossbows shoot cross-
          bow bolts.  Slings hurl rocks and (other) stones (like gems).

               Enchanted weapons have a "plus"  (or  "to  hit  enhancement"
          which  can  be  either  positive  or  negative) that adds to your
          chance to hit and the damage you do to a monster.  The  only  way
          to determine a weapon's enchantment is to have it magically iden-
          tified somehow.  Most weapons are subject to some type of  damage
          like rust.  Such "erosion" damage can be repaired.

               The  chance  that an attack will successfully hit a monster,
          and the amount of damage such a hit will do,  depends  upon  many
          factors.   Among them are: type of weapon, quality of weapon (en-
          chantment and/or erosion), experience level, strength, dexterity,
          encumbrance,  and  proficiency  (see below).  The monster's armor
          class--a general defense rating, not necessarily due  to  wearing
          of  armor--is  a factor too; also, some monsters are particularly
          vulnerable to certain types of weapons.

               Many weapons can be wielded in one hand; some  require  both
          hands.   When  wielding  a  two-handed weapon, you can not wear a
          shield, and vice versa.  When wielding a one-handed  weapon,  you
          can  have  another  weapon ready to use by setting things up with
          the `x' command, which exchanges  your  primary  (the  one  being
          wielded)  and  alternate weapons.  And if you have proficiency in
          the "two weapon combat" skill, you may wield both weapons  simul-
          taneously as primary and secondary; use the `X' command to engage
          or disengage that.  Only some types  of  characters  (barbarians,
          for instance) have the necessary skill available.  Even with that
          skill, using two weapons at once incurs a penalty in  the  chance
          to hit your target compared to using just one weapon at a time.

               There  might be times when you'd rather not wield any weapon
          at all.  To accomplish that, wield `-', or else use the `A'  com-
          mand  which  allows you to unwield the current weapon in addition
          to taking off other worn items.

               Those of you in the audience who are AD&D players, be  aware
          that each weapon which existed in AD&D does roughly the same dam-
          age to monsters in NetHack.  Some of  the  more  obscure  weapons
          (such as the aklys, lucern hammer, and bec-de-corbin) are defined


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              44



          in an appendix to Unearthed Arcana, an AD&D supplement.

               The commands to use weapons are `w'  (wield),  `t'  (throw),
          `f'  (fire),  `Q'  (quiver), `x' (exchange), `X' (twoweapon), and
          "#enhance" (see below).

          7.2.1.  Throwing and shooting

               You can throw just about anything via the `t'  command.   It
          will  prompt  for the item to throw; picking `?' will list things
          in your inventory which are considered likely to  be  thrown,  or
          picking `*' will list your entire inventory.  After you've chosen
          what to throw, you will be prompted for a direction  rather  than
          for  a specific target.  The distance something can be thrown de-
          pends mainly on the type of object and your strength.  Arrows can
          be  thrown  by  hand,  but can be thrown much farther and will be
          more likely to hit when thrown while you are wielding a bow.

               Some weapons will return when thrown.  A boomerang--provided
          it  fails  to  hit  anything--is an obvious example.  If an aklys
          (thonged club) is thrown while it is wielded, it will return even
          when it hits something.  A sufficiently strong hero can throw the
          warhammer Mjollnir; when thrown by a Valkyrie it will return too.
          However,  aklyses  and Mjollnir occasionally fail to return.  Re-
          turning thrown objects occasionally fail to be caught,  sometimes
          even hitting the thrower, but when caught they become re-wielded.

               You  can  simplify  the  throwing operation by using the `Q'
          command to select your preferred "missile", then  using  the  `f'
          command  to  throw  it.   You'll  be  prompted for a direction as
          above, but you don't have to specify which  item  to  throw  each
          time you use `f'.  There is also an option, autoquiver, which has
          NetHack choose another item to automatically fill your quiver (or
          quiver  sack,  or have at the ready) when the inventory slot used
          for `Q' runs out.  If your quiver is empty, autoquiver is  false,
          and you are wielding a weapon which returns when thrown, you will
          throw that weapon instead of filling the quiver.  The  fire  com-
          mand  also  has extra assistance, if fireassist is on it will try
          to wield a launcher matching the ammo in the quiver.

               Some characters have the ability to throw or shoot a  volley
          of  multiple  items  (from  the  same  stack) in a single action.
          Knowing how to load several rounds of ammunition at once--or hold
          several  missiles  in your hand--and still hit a target is not an
          easy task.  Rangers are among those who are adept at  this  task,
          as  are  those  with  a high level of proficiency in the relevant
          weapon skill (in bow skill if you're wielding one  to  shoot  ar-
          rows, in crossbow skill if you're wielding one to shoot bolts, or
          in sling skill if you're wielding one to shoot stones).  The num-
          ber  of items that the character has a chance to fire varies from
          turn to turn.  You can explicitly limit the number  of  shots  by
          using  a numeric prefix before the `t' or `f' command.  For exam-
          ple, "2f" (or "n2f" if using number_pad mode) would  ensure  that
          at most 2 arrows are shot even if you could have fired 3.  If you


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              45



          specify a larger number than would have been shot ("4f"  in  this
          example),  you'll  just end up shooting the same number (3, here)
          as if no limit had been specified.  Once the volley is in motion,
          all  of the items will travel in the same direction; if the first
          ones kill a monster, the others can still  continue  beyond  that
          spot.

          7.2.2.  Weapon proficiency

               You will have varying degrees of skill in the weapons avail-
          able.  Weapon proficiency, or weapon skills, affect how well  you
          can  use  particular  types of weapons, and you'll be able to im-
          prove your skills as you progress through a  game,  depending  on
          your role, your experience level, and use of the weapons.

               For  the  purposes of proficiency, weapons have been divided
          up  into  various  groups  such  as  daggers,  broadswords,   and
          polearms.   Each  role has a limit on what level of proficiency a
          character can achieve for each group.  For instance, wizards  can
          become  highly  skilled in daggers or staves but not in swords or
          bows.

               The "#enhance" extended command is used  to  review  current
          weapons  proficiency (also spell proficiency) and to choose which
          skill(s) to improve when you've used one or more skills enough to
          become  eligible  to do so.  The skill rankings are "none" (some-
          times also referred to as "restricted", because you won't be able
          to  advance), "unskilled", "basic", "skilled", and "expert".  Re-
          stricted skills simply will not appear in the list shown by "#en-
          hance".   (Divine  intervention  might  unrestrict  a  particular
          skill, in which case it will start at unskilled and be limited to
          basic.)   Some  characters can enhance their barehanded combat or
          martial arts skill beyond expert to "master" or "grand master".

               Use of a weapon in which you're restricted or unskilled will
          incur a modest penalty in the chance to hit a monster and also in
          the amount of damage done when you do hit; at basic level,  there
          is  no  penalty  or bonus; at skilled level, you receive a modest
          bonus in the chance to hit and amount of damage done;  at  expert
          level,  the  bonus  is  higher.  A successful hit has a chance to
          boost your training towards the next skill level  (unless  you've
          already  reached  the  limit for this skill).  Once such training
          reaches the threshold for that next level, you'll  be  told  that
          you  feel  more  confident in your skills.  At that point you can
          use "#enhance" to increase one or more skills.  Such  skills  are
          not  increased automatically because there is a limit to your to-
          tal overall skills, so you need to actively choose  which  skills
          to enhance and which to ignore.

          7.2.3.  Two-Weapon combat

               Some characters can use two weapons at once.  Setting things
          up to do so can seem cumbersome but becomes  second  nature  with
          use.   To  wield  two  weapons,  you need to use the "#twoweapon"


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              46



          command.  But first you need to  have  a  weapon  in  each  hand.
          (Note  that  your two weapons are not fully equal; the one in the
          hand you normally wield with is considered primary and the  other
          one  is  considered secondary.  The most noticeable difference is
          after you stop--or before you begin,  for  that  matter--wielding
          two  weapons at once.  The primary is your wielded weapon and the
          secondary is just an item in your inventory that's been designat-
          ed as alternate weapon.)

               If your primary weapon is wielded but your off hand is empty
          or has the wrong weapon, use the sequence `x', `w', `x' to  first
          swap  your primary into your off hand, wield whatever you want as
          secondary weapon, then swap them  both  back  into  the  intended
          hands.  If your secondary or alternate weapon is correct but your
          primary one is not, simply use `w' to wield the primary.  Lastly,
          if  neither  hand  holds the correct weapon, use `w', `x', `w' to
          first wield the intended secondary, swap it to off hand, and then
          wield the primary.

               The  whole  process  can  be simplified via use of the push-
          weapon option.  When it is enabled, then using `w' to wield some-
          thing  causes  the currently wielded weapon to become your alter-
          nate weapon.  So the sequence `w', `w' can be used to first wield
          the weapon you intend to be secondary, and then wield the one you
          want as primary which will push the first  into  secondary  posi-
          tion.

               When  in  two-weapon combat mode, using the `X' command tog-
          gles back to single-weapon mode.  Throwing or dropping either  of
          the weapons or having one of them be stolen or destroyed will al-
          so make you revert to single-weapon combat.

          7.3.  Armor (`[')

               Lots of unfriendly things lurk about; you need armor to pro-
          tect yourself from their blows.  Some types of armor offer better
          protection than others.  Your armor class is a  measure  of  this
          protection.  Armor class (AC) is measured as in AD&D, with 10 be-
          ing the equivalent of no armor, and lower numbers meaning  better
          armor.   Each  suit  of armor which exists in AD&D gives the same
          protection in NetHack.

               Here is a list of the armor class values provided  by  suits
          of armor:
                     Dragon scale mail                         1
                     Plate mail, Crystal plate mail            3
                     Bronze plate mail, Splint mail,
                        Banded mail, Dwarvish mithril-coat     4
                     Chain mail, Elven mithril-coat            5
                     Scale mail, Orcish chain mail             6
                     Ring mail, Studded leather armor,
                        Dragon scales                          7
                     Leather armor, Orcish ring mail           8

                     none                                     10

               You  can  also  wear other pieces of armor (cloak over suit,
          shirt under suit, helmet, gloves, boots, shield)  to  lower  your
          armor  class  even  further.   Most of these provide a one or two
          point improvement to AC (making the  overall  value  smaller  and
          eventually  negative)  but  can also be enchanted.  Shirts are an
          exception; they don't provide any  protection  unless  enchanted.
          Some cloaks also don't improve AC when unenchanted but all cloaks
          offer some protection against rust or corrosion to suits worn un-
          der them and against some monster touch attacks.

               If  a piece of armor is enchanted, its armor protection will
          be better (or worse) than normal, and its "plus" (or minus)  will
          subtract  from  your  armor  class.  For example, a +1 chain mail
          would give you better protection than normal chain mail, lowering
          your  armor class one unit further to 4.  When you put on a piece
          of armor, you immediately  find  out  the  armor  class  and  any
          "plusses" it provides.  Cursed pieces of armor usually have nega-
          tive enchantments (minuses) in addition to being unremovable.

               Many types of armor are subject to some kind of damage  like
          rust.   Such damage can be repaired.  Some types of armor may in-
          hibit spell casting.

               The nudist option can be set (prior to game  start)  to  at-
          tempt  to play the entire game without wearing any armor (a self-
          imposed challenge which is extremely difficult to accomplish).

               The commands to use armor are `W' (wear) and `T' (take off).
          The  `A'  command  can be used to take off armor as well as other
          worn items.  Also, `P' (put on) and `R' (remove) which  are  nor-
          mally  for accessories can be used for armor, but pieces of armor
          won't be shown as likely candidates in a prompt for choosing what
          to put on or remove.

          7.4.  Food (`%')

               Food  is  necessary  to survive.  If you go too long without
          eating you will faint, and eventually die  of  starvation.   Some
          types  of  food  will  spoil, and become unhealthy to eat, if not
          protected.  Food stored in ice boxes or tins ("cans") will usual-
          ly  stay fresh, but ice boxes are heavy, and tins take a while to
          open.

               When you kill monsters, they usually leave corpses which are
          also  "food."   Many, but not all, of these are edible; some also
          give you special powers when you eat them.  A good rule of  thumb
          is "you are what you eat."

               Some character roles and some monsters are vegetarian.  Veg-
          etarian monsters will typically never eat animal  corpses,  while
          vegetarian  players  can,  but  with some rather unpleasant side-


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              48



          effects.

               You can name one food item after something you like  to  eat
          with the fruit option.

               The command to eat food is `e'.

          7.5.  Scrolls (`?')

               Scrolls  are labeled with various titles, probably chosen by
          ancient wizards for their amusement value (for example "READ ME,"
          or  "THANX  MAUD"  backwards).   Scrolls disappear after you read
          them (except for blank ones, without magic spells on them).

               One of the most useful of these is the scroll  of  identify,
          which can be used to determine what another object is, whether it
          is cursed or blessed, and how many uses it has  left.   Some  ob-
          jects  of  subtle  enchantment  are difficult to identify without
          these.

               A mail daemon may run up and deliver mail to you as a scroll
          of  mail  (on  versions compiled with this feature).  To use this
          feature on versions where NetHack mail delivery is  triggered  by
          electronic  mail  appearing  in your system mailbox, you must let
          NetHack know where to look for new mail by setting the "MAIL" en-
          vironment variable to the file name of your mailbox.  You may al-
          so want to set the "MAILREADER" environment variable to the  file
          name of your favorite reader, so NetHack can shell to it when you
          read the scroll.  On versions of NetHack where mail  is  randomly
          generated  internal  to the game, these environment variables are
          ignored.  You can disable the mail daemon by turning off the mail
          option.

               The command to read a scroll is `r'.

          7.6.  Potions (`!')

               Potions  are distinguished by the color of the liquid inside
          the flask.  They disappear after you quaff them.

               Clear potions are potions of  water.   Sometimes  these  are
          blessed or cursed, resulting in holy or unholy water.  Holy water
          is the bane of the undead, so potions  of  holy  water  are  good
          things  to throw (`t') at them.  It is also sometimes very useful
          to dip ("#dip") an object into a potion.

               The command to drink a potion is `q' (quaff).

          7.7.  Wands (`/')

               Wands usually have multiple magical charges.  Some types  of
          wands require a direction in which to zap them.  You can also zap
          them at yourself (just give a `.' or `s' for the direction).   Be
          warned,  however, for this is often unwise.  Other types of wands


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              49



          don't require a direction.  The number of charges in  a  wand  is
          random and decreases by one whenever you use it.

               When  the number of charges left in a wand becomes zero, at-
          tempts to use the wand will usually result in nothing  happening.
          Occasionally, however, it may be possible to squeeze the last few
          mana points from an otherwise spent wand, destroying  it  in  the
          process.   A  wand  may be recharged by using suitable magic, but
          doing so runs the risk of causing it to explode.  The chance  for
          such  an  explosion starts out very small and increases each time
          the wand is recharged.

               In a truly desperate situation, when your back is up against
          the  wall,  you might decide to go for broke and break your wand.
          This is not for the faint of heart.  Doing so  will  almost  cer-
          tainly cause a catastrophic release of magical energies.

               When  you have fully identified a particular wand, inventory
          display will include additional information in  parentheses:  the
          number  of  times  it  has been recharged followed by a colon and
          then by its current number of charges.  A current charge count of
          -1 is a special case indicating that the wand has been cancelled.

               The  command  to use a wand is `z' (zap).  To break one, use
          the `a' (apply) command.

          7.8.  Rings (`=')

               Rings are very useful items, since they are relatively  per-
          manent  magic,  unlike  the  usually fleeting effects of potions,
          scrolls, and wands.

               Putting on a ring activates its magic.  You can wear at most
          two rings at any time, one on the ring finger of each hand.

               Most  worn rings also cause you to grow hungry more rapidly,
          the rate varying with the type of ring.

               When wearing gloves, rings  are  worn  underneath.   If  the
          gloves  are  cursed, rings cannot be put on and any already being
          worn cannot be removed.  When  worn  gloves  aren't  cursed,  you
          don't  have to manually take them off before putting on or remov-
          ing a ring and then re-wear them after.  That's  done  implicitly
          to avoid unnecessary tedium.

               The commands to use rings are `P' (put on) and `R' (remove).
          `A', `W', and `T' can also be used; see Amulets.

          7.9.  Spellbooks (`+')

               Spellbooks are tomes of mighty magic.  When studied with the
          `r'  (read) command, they transfer to the reader the knowledge of
          a spell (and therefore eventually become unreadable)--unless  the
          attempt backfires.  Reading a cursed spellbook or one with mystic


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              50



          runes beyond your ken can be harmful to your health!

               A spell (even when learned) can also backfire when you  cast
          it.   If  you  attempt to cast a spell well above your experience
          level, or if you have little skill  with  the  appropriate  spell
          type,  or  cast  it at a time when your luck is particularly bad,
          you can end up wasting both the energy and the time  required  in
          casting.

               Casting  a  spell  calls  forth magical energies and focuses
          them with your naked mind.  Some of the magical  energy  released
          comes  from  within you.  Casting temporarily drains your magical
          power, which will slowly be recovered, and causes you to need ad-
          ditional  food.   Casting of spells also requires practice.  With
          practice, your skill in each category of spell casting  will  im-
          prove.   Over  time, however, your memory of each spell will dim,
          and you will need to relearn it.

               Some spells require a direction in which to cast them, simi-
          lar  to  wands.   To cast one at yourself, just give a `.' or `s'
          for the direction.  A few spells require you to pick a target lo-
          cation  rather  than  just specify a particular direction.  Other
          spells don't require any direction or target.

               Just as weapons are divided into groups in which a character
          can  become proficient (to varying degrees), spells are similarly
          grouped.  Successfully casting a spell exercises its skill group;
          using  the "#enhance" command to advance a sufficiently exercised
          skill will affect all spells within the  group.   Advanced  skill
          may  increase the potency of spells, reduce their risk of failure
          during casting attempts, and improve the accuracy of the estimate
          for  how much longer they will be retained in your memory.  Skill
          slots are shared with weapons skills.  (See also the  section  on
          "Weapon proficiency".)

               Casting a spell also requires flexible movement, and wearing
          various types of armor may interfere with that.

               The command to read a spellbook is the same as for  scrolls,
          `r' (read).  The `+' command lists each spell you know along with
          its level, skill category, chance of failure when casting, and an
          estimate  of  how strongly it is remembered.  The `Z' (cast) com-
          mand casts a spell.

          7.10.  Tools (`(')

               Tools are miscellaneous objects with various purposes.  Some
          tools  have  a limited number of uses, akin to wand charges.  For
          example, lamps burn out after a while.  Other tools are  contain-
          ers, which objects can be placed into or taken out of.

               Some  tools (such as a blindfold) can be worn and can be put
          on and removed  like  other  accessories  (rings,  amulets);  see
          Amulets.   Other  tools  (such  as  pick-axe)  can  be wielded as


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              51



          weapons in addition to being applied for their usual purpose, and
          in  some  cases (again, pick-axe) become wielded as a weapon even
          when applied.

               The blind option can be set (prior to game start) to attempt
          to play the entire game without being able to see (a self-imposed
          challenge which is very difficult to accomplish).

               The command to use a tool is `a' (apply).

          7.10.1.  Containers

               You may encounter bags, boxes, and chests in  your  travels.
          A  tool of this sort can be opened with the "#loot" extended com-
          mand when you are standing on top of it (that  is,  on  the  same
          floor  spot), or with the `a' (apply) command when you are carry-
          ing it.  However, chests are often locked, and are  in  any  case
          unwieldy  objects.   You must set one down before unlocking it by
          using a key or lock-picking tool with the `a' (apply) command, by
          kicking  it  with the `^D' command, or by using a weapon to force
          the lock with the "#force" extended command.

               Some chests are trapped, causing nasty things to happen when
          you unlock or open them.  You can check for and try to deactivate
          traps with the "#untrap" extended command.

          7.11.  Amulets (`"')

               Amulets are very similar to rings, and often more  powerful.
          Like rings, amulets have various magical properties, some benefi-
          cial, some harmful, which are activated by putting them on.

               Only one amulet may be worn at a  time,  around  your  neck.
          Like  wearing  rings,  wearing an amulet affects your metabolism,
          causing you to grow hungry more rapidly.

               The commands to use amulets are the same as for  rings,  `P'
          (put  on)  and  `R'  (remove).  `A' can be used to remove various
          worn items including amulets.  Also, `W'  (wear)  and  `T'  (take
          off)  which  are  normally  for armor can be used for amulets and
          other accessories (rings and eyewear), but accessories  won't  be
          shown  as likely candidates in a prompt for choosing what to wear
          or take off.

          7.12.  Gems (`*')

               Some gems are valuable, and can be sold for a lot  of  gold.
          They  are  also a far more efficient way of carrying your riches.
          Valuable gems increase your score if you bring them with you when
          you exit.

               Other small rocks are also categorized as gems, but they are
          much less valuable.  All rocks, however, can be used  as  projec-
          tile  weapons  (if  you  have a sling).  In the most desperate of


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              52



          cases, you can still throw them by hand.

          7.13.  Large rocks (``')

               Statues and boulders are not particularly  useful,  and  are
          generally  heavy.   It  is rumored that some statues are not what
          they seem.

               Boulders occasionally block your path.   You  can  push  one
          forward (by attempting to walk onto its spot) when nothing blocks
          its path, or you can smash it into a pile  of  small  rocks  with
          breaking  magic  or  a  pick-axe.   It is possible to move onto a
          boulder's location if certain conditions are met; ordinarily  one
          of  those  conditions  is that pushing it any further be blocked.
          Using the move-without-picking-up prefix (default key `m')  prior
          to  the direction of movement will attempt to move to a boulder's
          location without pushing it in addition to the prefix's usual ac-
          tion of suppressing auto-pickup at the destination.

               Very  large humanoids (giants and their ilk) have been known
          to pick up boulders and use them as missile weapons.

               Unlike boulders, statues can't be pushed, but don't need  to
          be  because  they don't block movement.  They can be smashed into
          rocks though.

               For some configurations  of  the  program,  statues  are  no
          longer  shown  as  ``' but by the letter representing the monster
          they depict instead.

          7.14.  Gold (`$')

               Gold adds to your score, and you can  buy  things  in  shops
          with  it.  There are a number of monsters in the dungeon that may
          be influenced by the amount of gold you are carrying (shopkeepers
          aside).

               Gold  pieces  are  the only type of object where bless/curse
          state does not apply.  They're  always  uncursed  but  never  de-
          scribed  as  uncursed  even if you turn off the implicit_uncursed
          option.  You can set the goldX option if you prefer to have  gold
          pieces  be  treated  as  bless/curse state unknown rather than as
          known to be uncursed.  Only matters when you're using  an  object
          selection prompt that can filter by "BUCX" state.

          7.15.  Persistence of Objects

               Normally, if you have seen an object at a particular map lo-
          cation and move to another location where you can't directly  see
          that  object  any  more, it will continue to be displayed on your
          map.  That remains the case even if it is not actually there  any
          more--perhaps  a monster has picked it up or it has rotted away--
          until you can see or feel that location again.  One  notable  ex-
          ception  is  that  if the object gets covered by the "remembered,


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              53



          unseen monster" marker.  When that marker is later removed  after
          you've verified that no monster is there, you will have forgotten
          that there was any object there regardless of whether the  unseen
          monster  actually took the object.  If the object is still there,
          then once you see or feel that location again you will re-discov-
          er the object and resume remembering it.

               The situation is the same for a pile of objects, except that
          only the top item of the pile is displayed.  The hilite_pile  op-
          tion  can be enabled in order to show an item differently when it
          is the top one of a pile.

          8.  Conduct

               As if winning NetHack were  not  difficult  enough,  certain
          players  seek to challenge themselves by imposing restrictions on
          the way they play the game.  The game automatically  tracks  some
          of  these  challenges,  which can be checked at any time with the
          #conduct command or at the end of the game.  When you perform  an
          action  which  breaks  a  challenge, it will no longer be listed.
          This gives players extra "bragging rights" for winning  the  game
          with  these  challenges.  Note that it is perfectly acceptable to
          win the game without resorting to these restrictions and that  it
          is  unusual  for  players  to adhere to challenges the first time
          they win the game.

               Several of the challenges are related  to  eating  behavior.
          The  most difficult of these is the foodless challenge.  Although
          creatures can survive long periods of time without food, there is
          a  physiological  need for water; thus there is no restriction on
          drinking beverages, even if they provide some  minor  food  bene-
          fits.   Calling  upon  your god for help with starvation does not
          violate any food challenges either.

               A strict vegan diet is one which  avoids  any  food  derived
          from animals.  The primary source of nutrition is fruits and veg-
          etables.  The corpses and tins of blobs (`b'), jellies (`j'), and
          fungi  (`F') are also considered to be vegetable matter.  Certain
          human food is prepared without animal  products;  namely,  lembas
          wafers,  cram  rations, food rations (gunyoki), K-rations, and C-
          rations.  Metal or another normally indigestible  material  eaten
          while polymorphed into a creature that can digest it is also con-
          sidered vegan food.  Note however that eating  such  items  still
          counts against foodless conduct.

               Vegetarians  do  not eat animals; however, they are less se-
          lective about eating animal byproducts than vegans.  In  addition
          to the vegan items listed above, they may eat any kind of pudding
          (`P') other than the black puddings, eggs and food made from eggs
          (fortune  cookies  and pancakes), food made with milk (cream pies
          and candy bars), and lumps of royal jelly.  Monks are expected to
          observe a vegetarian diet.

               Eating  any kind of meat violates the vegetarian, vegan, and
          foodless conducts.  This includes tripe rations, the  corpses  or
          tins  of  any monsters not mentioned above, and the various other
          chunks of meat found in the dungeon.  Swallowing and digesting  a
          monster while polymorphed is treated as if you ate the creature's
          corpse.  Eating leather, dragon hide, or bone items  while  poly-
          morphed  into  a  creature  that can digest it, or eating monster
          brains while polymorphed into a mind flayer, is considered eating
          an animal, although wax is only an animal byproduct.

               Regardless  of  conduct,  there will be some items which are
          indigestible, and others which are hazardous  to  eat.   Using  a
          swallow-and-digest attack against a monster is equivalent to eat-
          ing the monster's corpse.  Please note that the term  "vegan"  is
          used  here  only  in  the context of diet.  You are still free to
          choose not to use  or  wear  items  derived  from  animals  (e.g.
          leather,  dragon hide, bone, horns, coral), but the game will not
          keep track of this for you.  Also note that "milky"  potions  may
          be a translucent white, but they do not contain milk, so they are
          compatible with a vegan  diet.   Slime  molds  or  player-defined
          "fruits",  although  they  could  be  anything from "cherries" to
          "pork chops", are also assumed to be vegan.

               An atheist is one who rejects religion.  This means that you
          cannot  #pray,  #offer  sacrifices  to  any god, #turn undead, or
          #chat with a priest.  Particularly selective  readers  may  argue
          that  playing  Monk or Priest characters should violate this con-
          duct; that is a choice left to the player.  Offering  the  Amulet
          of  Yendor  to  your  god is necessary to win the game and is not
          counted against this conduct.  You are also not penalized for be-
          ing  spoken  to  by an angry god, priest(ess), or other religious
          figure; a true atheist would hear the words but attach no special
          meaning to them.

               Most  players  fight with a wielded weapon (or tool intended
          to be wielded as a weapon).  Another challenge is to win the game
          without  using such a wielded weapon.  You are still permitted to
          throw, fire, and kick weapons; use a wand, spell, or  other  type
          of item; or fight with your hands and feet.

               In  NetHack,  a  pacifist  refuses to cause the death of any
          other monster (i.e. if you would get experience for  the  death).
          This  is a particularly difficult challenge, although it is still
          possible to gain experience by other means.

               An illiterate character does not read or  write.   This  in-
          cludes reading a scroll, spellbook, fortune cookie message, or t-
          shirt; writing a scroll; or making an engraving of anything other
          than  a  single  "X"  (the traditional signature of an illiterate
          person).  Reading an engraving, or any item  that  is  absolutely
          necessary  to  win the game, is not counted against this conduct.
          The identity of scrolls and spellbooks (and knowledge of  spells)
          in  your  starting  inventory  is assumed to be learned from your
          teachers prior to the start of the game and isn't counted.

               There is a side-branch to the main dungeon called "Sokoban,"
          briefly  described  in  the earlier section about Traps.  As men-
          tioned there, the goal is to push boulders into pits and/or holes
          to  plug  those  in order to both get the boulders out of the way
          and be able to go past the traps.  There are some special "rules"
          that  are  active when in that branch of the dungeon.  Some rules
          can't be bypassed, such as being unable to push a boulder  diago-
          nally.  Other rules can, such as not smashing boulders with magic
          or tools, but doing so causes you to receive a luck penalty.   No
          message  about  that is given at the time, but it is tracked as a
          conduct.  The #conduct command and end of  game  disclosure  will
          report  whether  you have abided by the special rules of Sokoban,
          and if not, how many times you violated them, providing you  with
          a way to discover which actions incur bad luck so that you can be
          better informed about whether or not to avoid repeating those ac-
          tions  in  the  future.  (Note:  the Sokoban conduct will only be
          displayed if you have entered the Sokoban branch of  the  dungeon
          during the current game.  Once that has happened, it becomes part
          of disclosed conduct even if you haven't done anything  interest-
          ing  there.  Ending the game with "never broke the Sokoban rules"
          conduct is most meaningful if you also manage to perform the "ob-
          tained the Sokoban prize" achievement (see Achievements below).)

               There  are several other challenges tracked by the game.  It
          is possible to eliminate one or more species of monsters by geno-
          cide;  playing  without  this  feature is considered a challenge.
          When the game offers you an opportunity to genocide monsters, you
          may  respond with the monster type "none" if you want to decline.
          You can change the form of an item into another item of the  same
          type  ("polypiling")  or  the  form of your own body into another
          creature ("polyself") by wand, spell,  or  potion  of  polymorph;
          avoiding  these effects are each considered challenges.  Polymor-
          phing monsters, including pets, does not break  either  of  these
          challenges.   Finally,  you  may sometimes receive wishes; a game
          without an attempt to wish for any items is a challenge, as is  a
          game  without wishing for an artifact (even if the artifact imme-
          diately disappears).  When the game offers you an opportunity  to
          make  a wish for an item, you may choose "nothing" if you want to
          decline.

          8.1.  Achievements

               End of game disclosure will also  display  various  achieve-
          ments  representing  progress  toward  ultimate ascension, if any
          have been attained.  They aren't directly related to conduct  but
          are  grouped  with it because they fall into the same category of
          "bragging rights" and to limit the  number  of  questions  during
          disclosure.   Listed  here roughly in order of difficulty and not
          necessarily in the order in which you might accomplish them.

          Notes:

               Achievements  are  recorded and subsequently reported in the
          order in which they happen during your current game  rather  than
          the order listed here.

               There  are nine <Rank> titles for each role, bestowed at ex-
          perience levels 1, 3, 6, 10, 14, 18, 22, 26, and 30.  The one for
          experience  level  1  is  not recorded as an achievement.  Losing
          enough levels to revert to lower rank(s)  does  not  discard  the
          corresponding achievement(s).

               There's  no  guaranteed Novel so the achievement to read one
          might not always be attainable (except perhaps by wishing).  Sim-
          ilarly,  the  Big  Room level is not always present.  Unlike with
          the Novel, there's no way to wish for this opportunity.

               The "special items" hidden in Mines' End and Sokoban are not
          unique  but  are considered to be prizes or rewards for exploring
          those levels since doing so is  not  necessary  to  complete  the
          game.  Finding other instances of the same objects doesn't record
          the corresponding achievement.

               The Medusa achievement is recorded if she dies for any  rea-
          son,  even  if  you are not directly responsible, and only if she
          dies.

               The 5-note tune can be learned via trial and  error  with  a
          musical  instrument played closely enough--but not too close!--to
          the Castle level's drawbridge or can be given to you  via  prayer


          NetHack 3.7                                     December 28, 2022

          boon.

               Blind and Nudist are also conducts, and they can only be en-
          abled by setting the correspondingly named option  in  NETHACKOP-
          TIONS or run-time configuration file prior to game start.  In the
          case of Blind, the option also enforces the conduct.  They aren't
          really significant accomplishments unless/until you make substan-
          tial progress into the dungeon.

          9.  Options

               Due to variations in personal tastes and conceptions of  how
          NetHack should do things, there are options you can set to change
          how NetHack behaves.

          9.1.  Setting the options

               Options may be set in a number of ways.   Within  the  game,
          the `O' command allows you to view all options and change most of
          them.  You can also set options automatically by placing them  in
          a  configuration file, or in the NETHACKOPTIONS environment vari-
          able.  Some versions of NetHack also have front-end programs that
          allow  you  to  set  options before starting the game or a global
          configuration for system administrators.

          9.2.  Using a configuration file

               The default name of the configuration file varies on differ-
          ent operating systems.

               On  UNIX,  Linux, and macOS it is ".nethackrc" in the user's
          home directory.  The file may not exist, but it is a normal ASCII
          text file and can be created with any text editor.

               On  Windows,  it  is  ".nethackrc" in the folder "\%USERPRO-
          FILE%\NetHack\3.7".  The file may not exist, but it is  a  normal
          ASCII  text  file can can be created with any text editor.  After
          running NetHack for the first time, you  should  find  a  default
          template  for  the configuration file named ".nethackrc.template"
          in "\%USERPROFILE%\NetHack\3.7".  If you had not created the con-
          figuration  file,  NetHack will create the configuration file for
          you using the default template file.

               On MS-DOS,  it  is  "defaults.nh"  in  the  same  folder  as
          nethack.exe.

               Any  line  in  the  configuration  file starting with `#' is
          treated as a comment and ignored.  Empty lines are ignored.

               Any line beginning with `[' and ending in `]' is  a  section
          marker (the closing `]' can be followed by whitespace and then an
          arbitrary comment beginning with  `#').   The  text  between  the
          square  brackets  is  the section name.  Section markers are only
          valid  after  a  CHOOSE  directive  and  their  names  are   case


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              58



          insensitive.  Lines after a section marker belong to that section
          up until another section starts or a marker without a name is en-
          countered  or  the  file ends.  Lines within sections are ignored
          unless a CHOOSE directive has selected that section.

               You can use different configuration directives in the  file,
          some of which can be used multiple times.  In general, the direc-
          tives are written in capital letters, followed by an equals sign,
          followed by settings particular to that directive.

               Here is a list of allowed directives:

          OPTIONS
            There  are  two types of options, boolean and compound options.
            Boolean options toggle a setting on or off, while compound  op-
            tions  take  more diverse values.  Prefix a boolean option with
            "no" or `!' to turn it off.  For compound options,  the  option
            name and value are separated by a colon.  Some options are per-
            sistent, and apply only to new games.  You can specify multiple
            OPTIONS directives, and multiple options separated by commas in
            a single OPTIONS directive.  (Comma separated options are  pro-
            cessed from right to left.)

            Example:

                 OPTIONS=dogname:Fido
                 OPTIONS=!legacy,autopickup,pickup_types:$"=/!?+

          HACKDIR
            Default  location  of  files  NetHack needs. On Windows HACKDIR
            defaults to the location of  the  NetHack.exe  or  NetHackw.exe
            file  so setting HACKDIR to override that is not usually neces-
            sary or recommended.

          LEVELDIR
            The location that in-progress level files are stored.  Defaults
            to HACKDIR, must be writable.

          SAVEDIR
            The  location  where saved games are kept. Defaults to HACKDIR,
            must be writable.

          BONESDIR
            The location that bones files are kept.  Defaults  to  HACKDIR,
            must be writable.

          LOCKDIR
            The  location  that  file  synchronization  locks  are  stored.
            Defaults to HACKDIR, must be writable.

          TROUBLEDIR
            The location that a record of game  aborts  and  self-diagnosed
            game problems is kept. Defaults to HACKDIR, must be writable.

          NetHack Guidebook                                              59



          AUTOCOMPLETE
            Enable or disable an extended command autocompletion.  Autocom-
            pletion has no effect for the X11 windowport.  You can  specify
            multiple  autocompletions.   To enable autocompletion, list the
            extended command.  Prefix the command with "!" to  disable  the
            autocompletion for that command.

            Example:

                 AUTOCOMPLETE=zap,!annotate

          AUTOPICKUP_EXCEPTION
            Set  exceptions to the pickup_types option.  See the "Configur-
            ing Autopickup Exceptions" section.

          BINDINGS
            Change the key bindings of some special  keys,  menu  accelera-
            tors,  extended  commands,  or  mouse buttons.  You can specify
            multiple bindings.  Format is key followed by the command, sep-
            arated by a colon.  See the "Changing Key Bindings" section for
            more information.

            Example:

                 BIND=^X:getpos.autodescribe

          CHOOSE
            Chooses at random one of the comma-separated parameters  as  an
            active section name.  Lines in other sections are ignored.

            Example:

                 OPTIONS=color
                 CHOOSE=char A,char B
                 [char A]
                 OPTIONS=role:arc,race:dwa,align:law,gender:fem
                 [char B]
                 OPTIONS=role:wiz,race:elf,align:cha,gender:mal
                 [] #end of CHOOSE
                 OPTIONS=!rest_on_space

            If  []  is  present, the preceding section is closed and no new
            section begins; whatever follows will be  common  to  all  sec-
            tions.   Otherwise  the  last section extends to the end of the
            options file.

          MENUCOLOR
            Highlight menu lines with different colors.  See the "Configur-

          ROGUESYMBOLS
            Custom symbols for for the rogue level's symbol set.  See  SYM-
            BOLS below.

          SOUND
            Define a sound mapping.  See the "Configuring User Sounds" sec-
            tion.

          SOUNDDIR
            Define the directory that contains the sound  files.   See  the
            "Configuring User Sounds" section.

          SYMBOLS
            Override  one  or  more  symbols in the symbol set used for all
            dungeon levels except for the special  rogue  level.   See  the
            "Modifying NetHack Symbols" section.

            Example:

                 # replace small punctuation (tick marks) with digits
                 SYMBOLS=S_boulder:0,S_golem:7

          WIZKIT
            Debug  mode  only:   extra  items  to add to initial inventory.
            Value is the name of a text file  containing  a  list  of  item
            names,  one  per line, up to a maximum of 128 lines.  Each line
            is processed by the function that handles wishing.

            Example:

                 WIZKIT=~/wizkit.txt



          Here is an example of configuration file contents:

          # Set your character's role, race, gender, and alignment.
          OPTIONS=role:Valkyrie, race:Human, gender:female, align:lawful
          #
          # Turn on autopickup, set automatically picked up object types

          9.3.  Using the NETHACKOPTIONS environment variable

               The NETHACKOPTIONS variable is  a  comma-separated  list  of
          initial  values for the various options.  Some can only be turned
          on or off.  You turn one of these on by adding the  name  of  the
          option  to  the list, and turn it off by typing a `!' or "no" be-
          fore the name.  Others take a character string as a  value.   You
          can  set  string  options  by  typing the option name, a colon or
          equals sign, and then the value of the string.  The value is ter-
          minated by the next comma or the end of string.

               For example, to set up an environment variable so that color
          is on, legacy is off, character name is set to "Blue Meanie", and
          named fruit is set to "lime", you would enter the command

          % setenv NETHACKOPTIONS "color,\!leg,name:Blue Meanie,fruit:lime"

          in  csh  (note  the  need to escape the `!' since it's special to
          that shell), or the pair of commands

          $ NETHACKOPTIONS="color,!leg,name:Blue Meanie,fruit:lime"
          $ export NETHACKOPTIONS

          in sh, ksh, or bash.

               The NETHACKOPTIONS value is effectively the same as a single
          OPTIONS directive in a configuration file.  The "OPTIONS=" prefix
          is implied and comma separated options are processed  from  right
          to left.  Other types of configuration directives such as BIND or
          MSGTYPE are not allowed.

               Instead of a comma-separated list of options, NETHACKOPTIONS
          can  be  set to the full name of a configuration file you want to
          use.  If that full name doesn't start with a  slash,  precede  it
          with  `@' (at-sign) to let NetHack know that the rest is intended
          as a file name.  If it does start with `/', the  at-sign  is  op-
          tional.

          9.4.  Customization options

               Here are explanations of what the various options do.  Char-
          acter strings that are too long may be truncated.   Some  of  the
          options listed may be inactive in your dungeon.

               Some  options  are  persistent,  and  are saved and reloaded
          along with the game.  Changing a persistent option in the config-
          uration file applies only to new games.

          acoustics
            Enable  messages  about what your character hears (default on).
            Note that this has nothing to do with your computer's audio ca-
            pabilities.  Persistent.

          alignment
            Your   starting   alignment  (align:lawful,  align:neutral,  or
            align:chaotic).  You may specify just the first  letter.   Many
            roles and the non-human races restrict which alignments are al-
            lowed.  See role for a description of how to  use  negation  to
            exclude choices.

            Default  is  random.  Cannot be set with the `O' command.  Per-
            sistent.

          autodescribe
            Automatically describe the terrain under cursor when  asked  to
            get a location on the map (default true).  The whatis_coord op-
            tion controls whether the description includes map coordinates.

          autodig
            Automatically dig if you are wielding a digging tool and moving
            into a place that can be dug (default false).  Persistent.

          autoopen
            Walking  into a closed door attempts to open it (default true).
            Persistent.

          autopickup
            Automatically pick up things onto which you move (default off).
            Persistent.

            See  pickup_types and also autopickup_exception for ways to re-
            fine the behavior.

            Note: prior to version 3.7, the default for autopickup was on.

          autoquiver
            This option controls what happens  when  you  attempt  the  `f'
            (fire)  command  when  nothing  is quivered or readied (default
            false).  When true, the  computer  will  fill  your  quiver  or
            quiver  sack  or make ready some suitable weapon.  Note that it
            will not take into account the blessed/cursed status,  enchant-
            ment, damage, or quality of the weapon; you are free to manual-
            ly fill your quiver or quiver sack or make ready with  the  `Q'
            command instead.  If no weapon is found or the option is false,
            the `t' (throw) command is executed instead.  Persistent.

          autounlock
            Controls what action to take when attempting  to  walk  into  a
            locked  door  or to loot a locked container.  Takes a plus-sign
            separated list of values:

            Untrap    - prompt about whether to attempt to find a trap;  it
                        might  fail  to  find  one even when present; if it
                        does find one, it will ask whether you want to  try
                        to  disarm the trap; if you decline, your character
                        will forget that the door or box is trapped;
            Apply-Key - if carrying a key or other unlocking  tool,  prompt


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              63



                        about using it;
            Kick      - kick the door (if you omit untrap or decline to at-
                        tempt untrap and you omit apply-key or you  lack  a
                        key or you decline to use the key; has no effect on
                        containers);
            Force     - try to force a container's lid with your  currently
                        wielded  weapon  (if  you omit untrap or decline to
                        attempt untrap and you omit apply-key or you lack a
                        key or you decline to use the key; has no effect on
                        doors);
            None      - none of the above; can't be combined with the other
                        choices.

            Omitting the value is treated as if autounlock:apply-key.  Pre-
            ceding autounlock with  `!'  or  "no"  is  treated  as  autoun-
            lock:none.

            Applying a key might set off a trap if the door or container is
            trapped.  Successfully kicking a door will break it and wake up
            nearby  monsters.   Successfully  forcing a container open will
            break its lock and might also destroy some of its  contents  or
            damage your weapon or both.

            The default is Apply-Key.  Persistent.

          blind
            Start the character permanently blind (default false).  Persis-
            tent.

          bones
            Allow saving and loading bones files (default  true).   Persis-
            tent.

          boulder
            Set  the  character  used  to  display boulders (default is the
            "large rock" class symbol, ``').

          catname
            Name your starting cat (for example "catname:Morris").   Cannot
            be set with the `O' command.

          character
            Synonym  for "role" to pick the type of your character (for ex-
            ample "character:Monk").  See role for more details.

          checkpoint
            Save game state after each level change, for possible  recovery
            after program crash (default on).  Persistent.

          cmdassist
            Have  the  game  provide some additional command assistance for
            new players if it detects some  anticipated  mistakes  (default
            on).

          confirm
            Have  user  confirm  attacks  on  pets,  shopkeepers, and other
            peaceable creatures (default on).  Persistent.

          dark_room
            Show out-of-sight areas of lit rooms (default on).  Persistent.

          disclose
            Controls what information the program  reveals  when  the  game
            ends.   Value  is  a space separated list of prompting/category
            pairs (default is "ni na nv ng nc no", prompt with default  re-
            sponse of `n' for each candidate).  Persistent.  The possibili-
            ties are:

                 i - disclose your inventory;
                 a - disclose your attributes;
                 v - summarize monsters that have been vanquished;
                 g - list monster species that have been genocided;
                 c - display your conduct; also achievements, if any;
                 o - display dungeon overview.

            Each disclosure possibility can optionally  be  preceded  by  a
            prefix  which  lets  you  refine  how it behaves.  Here are the
            valid prefixes:

                 y - prompt you and default to yes on the prompt;
                 n - prompt you and default to no on the prompt;
                 + - disclose it without prompting;
                 - - do not disclose it and do not prompt.

            The listing of vanquished monsters can be sorted, so there  are
            two additional choices for `v':

                 ? - prompt you and default to ask on the prompt;
                 # - disclose it without prompting, ask for sort order.

            Asking refers to picking one of the orderings from a menu.  The
            `+' disclose without prompting choice, or  being  prompted  and
            answering `y' rather than `a', will default to showing monsters
            in the traditional order, from high level to low level.

            Omitted categories are implicitly added with `n' prefix.  Spec-
            ified categories with omitted prefix implicitly use `+' prefix.
            Order of the disclosure categories  does  not  matter,  program
            display for end-of-game disclosure follows a set sequence.

            (for  example "disclose:yi na +v -g o") The example sets inven-
            tory to prompt and default to yes, attributes to prompt and de-
            fault to no, vanquished to disclose without prompting, genocid-
            ed to not disclose and not prompt, conduct to implicitly prompt
            and default to no, and overview to disclose without prompting.

            Note  that  the  vanquished monsters list includes all monsters
            killed by traps and each other as well  as  by  you.   And  the

            dungeon  overview shows all levels you had visited but does not
            reveal things about them that you hadn't discovered.

          dogname
            Name your starting dog (for example "dogname:Fang").  Cannot be
            set with the `O' command.

          extmenu
            Changes  the  extended  commands  interface to pop-up a menu of
            available commands.  It is keystroke compatible with the tradi-
            tional  interface  except that it does not require that you hit
            Enter.  It is implemented for the tty interface (default off).

            For the X11 interface, which always uses a menu for choosing an
            extended command, it controls whether the menu shows all avail-
            able commands (on) or just the subset of  commands  which  have
            traditionally been considered extended ones (off).

          female
            An  obsolete  synonym  for "gender:female".  Cannot be set with
            the `O' command.

          fireassist
            This option controls what happens  when  you  attempt  the  `f'
            (fire) and don't have an appropriate launcher, such as a bow or
            a sling, wielded.  If on,  you  will  automatically  wield  the
            launcher. Default is on.

          fixinv
            An  object's  inventory  letter  sticks to it when it's dropped
            (default on).  If this is off, dropping an  object  shifts  all
            the remaining inventory letters.  Persistent.

          force_invmenu
            Commands  asking for an inventory item show a menu instead of a
            text query with possible menu letters. Default is off.

          fruit
            Name a fruit after something  you  enjoy  eating  (for  example
            "fruit:mango")  (default  "slime mold").  Basically a nostalgic
            whimsy that NetHack uses from time to  time.   You  should  set
            this  to  something  you  find more appetizing than slime mold.
            Apples, oranges, pears, bananas, and melons  already  exist  in
            NetHack, so don't use those.

          gender
            Your  starting  gender (gender:male or gender:female).  You may
            specify just the first letter.  Although you can  still  denote
            your  gender using either of the deprecated male and female op-
            tions, if the gender option is also present it will take prece-
            dence.   See  role  for a description of how to use negation to
            exclude choices.

          NetHack Guidebook                                              66



            Default is random.  Cannot be set with the `O'  command.   Per-
            sistent.

          goldX
            When  filtering  objects  based  on  bless/curse  state (BUCX),
            whether to treat gold pieces as X (unknown  bless/curse  state,
            when  "on")  or  U  (known  to be uncursed, when "off", the de-
            fault).  Gold is never blessed or cursed, but  it  is  not  de-
            scribed as "uncursed" even when the implicit_uncursed option is
            "off".

          help
            If more information is available for an object looked  at  with
            the `/' command, ask if you want to see it (default on).  Turn-
            ing help off makes just looking at  things  faster,  since  you
            aren't  interrupted  with  the "More info?" prompt, but it also
            means that you might miss some interesting and/or important in-
            formation.  Persistent.

          herecmd_menu
            When  using  a  windowport  that supports mouse and clicking on
            yourself or next to you, show a menu of  possible  actions  for
            the  location.  Same as "#herecmdmenu" and "#therecmdmenu" com-
            mands.

          hilite_pet
            Visually distinguish pets from similar animals  (default  off).
            The  behavior  of  this option depends on the type of windowing
            you use.  In text windowing, text highlighting or inverse video
            is  often  used;  with tiles, generally displays a heart symbol
            near pets.

            With the curses interface, the petattr option controls  how  to
            highlight  pets  and setting it will turn the hilite_pet option
            on or off as warranted.

          hilite_pile
            Visually distinguish piles of objects from  individual  objects
            (default off).  The behavior of this option depends on the type
            of windowing you use.  In text windowing, text highlighting  or
            inverse  video  is often used; with tiles, generally displays a
            small plus-symbol beside the object on the top of the pile.

          hitpointbar

          implicit_uncursed
            Omit "uncursed" from object descriptions when it can be deduced
            from  other  aspects  of the description (default on).  Persis-
            tent.

            If you use menu coloring, you may want to turn this off.

          legacy
            Display an introductory message when starting the game (default
            on).  Persistent.

            held by your character as lit (default off).  Persistent.

          lootabc
            When using a menu to interact with a  container,  use  the  old
            `a',  `b', and `c' keyboard shortcuts rather than the mnemonics
            `o', `i', and `b' (default off).  Persistent.

          mail
            Enable mail delivery during the game (default on).  Persistent.

            `O' command.

          mention_decor
            Give  feedback  when walking onto various dungeon features such
            as stairs, fountains, or altars which are ordinarily  only  de-
            scribed  when  covered  by  one  or more objects (default off).
            Cannot be set with the `O' command.  Persistent.

            Give feedback when walking against a wall (default off).   Per-
            sistent.

          menucolors
            Enable  coloring  menu  lines  (default off).  See "Configuring
            Menu Colors" on how to configure the colors.

          menustyle
            Controls the interface used when you need to choose various ob-
            jects  (in  response  to  the Drop command, for instance).  The
            value specified should be the first letter of one of  the  fol-
            lowing:  traditional,  combination,  full, or partial.  Persis-
            tent.

            Traditional was the only interface  available  for  very  early
            versions;  it consists of a prompt for object class characters,
            followed by an object-by-object prompt for all  items  matching
            the  selected  object  class(es).   Combination  starts  with a

            prompt for object class(es) of interest, but  then  displays  a
            menu  of  matching  objects  rather  than prompting one-by-one.
            Full displays a menu of object classes rather than a  character
            prompt,  and  then  a  menu  of matching objects for selection.
            Partial skips the object class filtering and  immediately  dis-
            plays a menu of all objects.

          menu_deselect_all
            Key to deselect all items in a menu.  Default `-'.

          menu_deselect_page

          menu_first_page
            Key to jump to the first page in a menu.  Default `^'.

          menu_headings
            Controls  how  the  headings in a menu are highlighted.  Values
            are "none", "bold", "dim", "italic", "underline",  "blink",  or
            "inverse".  Not all ports can actually display all types.

          menu_invert_all
            Key to invert all items in a menu.  Default `@'.

          menu_invert_page
            Key to invert all items on this page of a menu.  Default `~'.

          menu_last_page
            Key to jump to the last page in a menu.  Default `|'.

          menu_next_page
            Key to go to the next menu page.  Default `>'.

          menu_objsyms
            Show  object symbols in menu headings in menus where the object
            symbols act as menu accelerators (default off).

          menu_overlay
            Do not clear the screen before drawing menus, and  align  menus
            to  the  right edge of the screen. Only for the tty port.  (de-
            fault on)

          menu_previous_page

            Key to select all items in a menu.  Default `.'.

          menu_select_page
            Key to select all items on this page of a menu.  Default `,'.

          menu_shift_left
            Key  to  scroll a menu--one which has been scrolled right--back
            to the left.  Implemented for perm_invent only  by  curses  and
            X11.  Default `{'.

          menu_shift_right
            Key  to  scroll  a menu which has text beyond the right edge to
            the right.  Implemented for perm_invent only by curses and X11.
            Default `}'.

          monpolycontrol
            Prompt for new form whenever any monster changes shape (default
            off).  Debug mode only.

          mouse_support
            Allow use of the mouse for input and  travel.   Valid  settings
            are:

                 0 - disabled
                 1 - enabled and make OS adjustments to support mouse use
                 2 - like 1 but does not make any OS adjustments

            Omitting  a  value  is  the  same  as specifying 1 and negating
            mouse_support is the same as specifying 0.

          msghistory
            The number of top line messages to keep (and be able to  recall
            with `^P') (default 20).  Cannot be set with the `O' command.

          msg_window
            Allows  you  to change the way recalled messages are displayed.
            Currently it is only supported for tty (all four  choices)  and
            for  curses  (`f'  and `r' choices, default `r').  The possible
            values are:

                 s - single message (default; only choice prior to 3.4.0);
                 c - combination, two messages as "single", then as "full";
                 f - full window, oldest message first;
                 r - full window reversed, newest message first.

            For backward compatibility, no  value  needs  to  be  specified
            (which  defaults  to  "full"),  or  it  can  be  negated (which
            defaults to "single").

          name
            Set your character's name (defaults to your  user  name).   You
            can  also set your character's role by appending a dash and one
            or more letters of the role (that is, by suffixing one of -A -B
            -C  -H  -K  -M  -P -Ra -Ro -S -T -V -W).  If -@ is used for the
            role, then a random one will be automatically  chosen.   Cannot
            be set with the `O' command.

          news
            Read the NetHack news file, if present (default on).  Since the

            news is shown at the beginning of the game, there's no point in
            setting this with the `O' command.

          nudist
            Start the character with no armor (default false).  Persistent.

          null
            Send padding nulls to the terminal (default on).  Persistent.

          number_pad
            Use  digit  keys instead of letters to move (default 0 or off).
            Valid settings are:

             0 - move by letters; "yuhjklbn"
             1 - move by numbers; digit `5' acts as `G' movement prefix
             2 - like 1 but `5' works as `g' prefix instead of as `G'
             3 - by numbers using phone key layout; 123 above, 789 below
             4 - combines 3 with 2; phone layout plus MS-DOS compatibility
            -1 - by letters but use `z' to go northwest, `y' to zap wands

            For backward compatibility, omitting a value  is  the  same  as
            specifying  1 and negating number_pad is the same as specifying
            0.  (Settings 2 and 4 are for compatibility with MS-DOS or  old
            PC Hack; in addition to the different behavior for `5', `Alt-5'
            acts as `G' and `Alt-0' acts as `I'.  Setting -1 is to accommo-
            date  some  QWERTZ keyboards which have the location of the `y'
            and `z' keys swapped.)  When moving  by  numbers,  to  enter  a
            count prefix for those commands which accept one (such as "12s"
            to search  twelve  times),  precede  it  with  the  letter  `n'
            ("n12s").

          packorder
            Specify   the   order   to   list   object  types  in  (default
            "")[%?+!=/(*`0_").  The value of this option should be a string
            containing the symbols for the various object types.  Any omit-
            ted types are filled in at the end from the previous order.

          paranoid_confirmation
            A space separated list of specific situations  where  alternate
            prompting  is  desired.   The  default  is  "paranoid_confirma-
            tion:pray swim".

            Confirm     - for any prompts which are set  to  require  "yes"
                          rather  than `y', also require "no" to reject in-
                          stead of accepting any non-yes response as no
            quit        - require "yes" rather than `y' to confirm quitting
                          the  game  or  switching into non-scoring explore
                          mode;
            die         - require "yes" rather than `y'  to  confirm  dying
                          (not  useful  in  normal play; applies to explore
                          mode);
            bones       - require "yes" rather than `y' to  confirm  saving
                          bones data when dying in debug mode;
            attack      - require   "yes"   rather   than  `y'  to  confirm

                          attacking a peaceful monster;
            wand-break  - require "yes" rather than `y' to confirm breaking
                          a wand;
            eating      - require  "yes" rather than `y' to confirm whether
                          to continue eating;
            Were-change - require "yes" rather than `y' to confirm changing
                          form  due  to lycanthropy when hero has polymorph
                          control;
            pray        - require `y' to confirm an attempt to pray  rather
                          than immediately praying; on by default;
            Remove      - require  selection from inventory for `R' and `T'
                          commands even when wearing  just  one  applicable
                          item.
            swim        - prevent walking into water or lava.
            all         - turn on all of the above.

            By  default,  the  pray choice is enabled, the others disabled.
            To disable it without setting any of  the  other  choices,  use
            "paranoid_confirmation:none".  To keep it enabled while setting
            any of the others, include it  in  the  list,  such  as  "para-
            noid_confirmation:attack pray Remove".

          perm_invent
            If  true,  always  display  your current inventory in a window.
            This only makes sense for windowing system interfaces that  im-
            plement this feature.

          petattr
            Specifies  one or more text highlighting attributes to use when
            showing pets  on  the  map.   Effectively  a  superset  of  the
            hilite_pet boolean option.  Curses interface only; value is one
            or more of the following letters.

                 n - Normal text (no highlighting)
                 i - Inverse video (default)
                 b - Bold text
                 u - Underlined text
                 k - blinKing text
                 d - Dim text
                 t - iTalic text
                 l - Left line indicator
                 r - Right line indicator

            Some of those choices might not work,  particularly  the  final
            three,  depending  upon terminal hardware or terminal emulation
            software.

            Currently multiple highlight-style letters can be  combined  by
            simply  stringing them together (for example, "bk"), but in the
            future they might require being separated by plus  signs  (such
            as  "b+k", which works already).  When using the `n' choice, it
            should be specified on its own, not in combination with any  of
            the other letters.

          pettype
            Specify  the  type  of  your  initial pet, if you are playing a
            character class that uses multiple types of pets; or choose  to
            have  no initial pet at all.  Possible values are "cat", "dog",
            "horse", and "none".  If the choice is not allowed for the role
            you  are  currently  playing, it will be silently ignored.  For
            example, "horse" will only be honored when  playing  a  knight.
            Cannot be set with the `O' command.

          pickup_burden
            When  you  pick  up  an item that would exceed this encumbrance
            level (Unencumbered, Burdened, streSsed,  straiNed,  overTaxed,
            or  overLoaded),  you  will  be  asked if you want to continue.
            (Default `S').  Persistent.

          pickup_thrown
            If this option is on and autopickup is also on, try to pick  up
            things  that  you threw, even if they aren't in pickup_types or
            match an autopickup exception.  Default is on.  Persistent.

          pickup_types
            Specify the object types to be picked up when autopickup is on.
            Default is all types.  Persistent.

            The value is a list of object symbols, such as pickup_types:$?!
            to pick up gold, scrolls, and potions.  You can  use  autopick-
            up_exception  configuration  file  lines  to further refine au-
            topickup behavior.

            There is no way to set pickup_types to "none".  (Setting it  to
            an  empty  value reverts to "all".)  If you want to avoid auto-
            matically picking up any types of items but do want to have au-
            topickup on in order to have autopickup_exception settings con-
            trol what you do and don't pick up, you can set pickup_types to
            `.'.   That  is  the  type  symbol for venom and you won't come
            across any venom items so won't unintentionally pick such up.

          pile_limit
            When walking across a pile of objects on the  floor,  threshold
            at  which the message "there are few/several/many objects here"
            is given instead of showing a popup list of those  objects.   A
            value  of 0 means "no limit" (always list the objects); a value
            of 1 effectively means "never show the objects" since the  pile
            size  will  always  be  at  least that big; default value is 5.
            Persistent.

          playmode
            Values are "normal", "explore", or "debug".   Allows  selection
            of  explore  mode  (also known as discovery mode) or debug mode
            (also known as wizard mode) instead of normal play.  Debug mode
            might  only be allowed for someone logged in under a particular
            user name (on multi-user systems) or  specifying  a  particular
            character name (on single-user systems) or it might be disabled
            entirely.  Requesting it  when  not  allowed  or  not  possible

            results in explore mode instead.  Default is normal play.

          pushweapon
            Using  the  `w' (wield) command when already wielding something
            pushes the old item into your alternate  weapon  slot  (default
            off).   Likewise  for  the `a' (apply) command if it causes the
            applied item to become wielded.  Persistent.

          quick_farsight
            When set, usually prevents the "you  sense  your  surroundings"
            message  where play pauses to allow you to browse the map when-
            ever clairvoyance randomly activates.  Some situations, such as
            being  underwater or engulfed, ignore this option.  It does not
            affect the clairvoyance spell where pausing to examine revealed
            objects  or  monsters is less intrusive.  Default is off.  Per-
            sistent.

          race
            Selects your race (for example, race:human).  Choices  are  hu-
            man,  dwarf,  elf, gnome, and orc but most roles restrict which
            of the non-human races are allowed.  See role for a description
            of how to use negation to exclude choices.

            Default  is  random.  Cannot be set with the `O' command.  Per-
            sistent.

          rest_on_space
            Make the space bar a synonym for the `.' (#wait)  command  (de-
            fault off).  Persistent.

          role
            Pick  your  type of character (for example, role:Samurai); syn-
            onym for character.  See name for an alternate method of speci-
            fying your role.

            This  option  can  also be used to limit selection when role is
            chosen randomly.  Use a space-separated list of roles  and  ei-
            ther  negate  each  one  or  negate  the option itself instead.
            Negation is accomplished in the same manner as with boolean op-
            tions,  by  prefixing  the  option  or its value(s) with `!' or
            "no".
            Examples:

                 OPTIONS=role:!arc !bar !kni
                 OPTIONS=!role:arc bar kni

            There can be multiple instances of the role option  if  they're
            all negations.

            Default  is  random.  Cannot be set with the `O' command.  Per-
            sistent.

          roguesymset
            This option may be used to select one of the named symbol  sets

            found  within  "symbols"  to alter the symbols displayed on the
            screen on the rogue level.

          rlecomp
            When writing out a save file, perform run length compression of
            the  map.  Not all ports support run length compression. It has
            no effect on reading an existing save file.

          runmode
            Controls the amount of screen updating for the map window  when
            engaged  in multi-turn movement (running via shift+direction or
            control+direction and so forth, or via the  travel  command  or
            mouse click).  The possible values are:

            teleport - update the map after movement has finished;
            run      - update the map after every seven or so steps;
            walk     - update the map after each step;
            crawl    - like walk, but pause briefly after each step.

            This option only affects the game's screen display, not the ac-
            tual results of moving.  The default is "run";  versions  prior
            to  3.4.1  used  "teleport" only.  Whether or not the effect is
            noticeable will depend upon the window port used or on the type
            of terminal.  Persistent.

          safe_pet
            Prevent  you from (knowingly) attacking your pets (default on).
            Persistent.

          safe_wait
            Prevents you from waiting or searching when next to  a  hostile
            monster (default on). Persistent.

          sanity_check
            Evaluate monsters, objects, and map prior to each turn (default
            off).  Debug mode only.

          scores
            Control what parts of the score list you are shown at  the  end
            (for   example  "scores:5  top  scores/4  around  my  score/own
            scores").  Only the first letter of each category (`t', `a', or
            `o') is necessary.  Persistent.

          showexp
            Show your accumulated experience points on bottom line (default
            off).  Persistent.

          showrace
            Display yourself as the glyph for your race,  rather  than  the
            glyph  for your role (default off).  Note that this setting af-
            fects only the appearance of the display, not the way the  game
            treats you.  Persistent.

          showscore
            Show your approximate accumulated score on bottom line (default
            off).  Persistent.

          silent
            Suppress terminal beeps (default on).  Persistent.

          sortdiscoveries
            Controls the sorting behavior for the output of the `\' and ``'
            commands.  Persistent.

            The possible values are:

            o - list  object types by class, in discovery order within each
                class; default;
            s - list object types by sortloot classification: by class,  by
                sub-class  within  class for classes which have substantial
                groupings (like helmets, boots, gloves, and  so  forth  for
                armor),  with  object  types partly-discovered via assigned
                name coming before fully identified types;
            c - list by class, alphabetically within each class;
            a - list alphabetically across all classes.

            Can be interactively set via the `O' command or via  using  the
            `m' prefix before the `\' or ``' command.

          sortloot
            Controls the sorting behavior of the pickup lists for inventory
            and #loot commands and some others.  Persistent.

            The possible values are:

            full - always sort the lists;
            loot - only sort the lists that don't  use  inventory  letters,
                   like with the #loot and pickup commands;
            none - show lists the traditional way without sorting; default.

          sortpack
            Sort  the  pack contents by type when displaying inventory (de-
            fault on).  Persistent.

          sortvanquished
            Controls the sorting behavior for the output of the #vanquished
            command.  Persistent.

            The possible values are:

            t - traditional--order by monster level; ties are broken by in-
                ternal monster index; default;
            d - order by monster difficulty rating; ties broken by internal
                index;
            a - order  alphabetically,  first  any unique monsters then all
                the others;
            c - order by monster class, by low to high  level  within  each

                class;
            n - order  by  count,  high to low; ties are broken by internal
                monster index;
            z - order by count, low to high; ties broken by internal index.

            Can be interactively set via the `m O' command or via using the
            `m' prefix before the #vanquished command.

          sparkle
            Display a sparkly effect when a monster (including yourself) is
            hit by an attack to which it is resistant (default  on).   Per-
            sistent.

          standout
            Boldface monsters and "--More--" (default off).  Persistent.

          statushilites
            Controls  how  many turns status hilite behaviors highlight the
            field.  If negated or set to zero,  disables  status  hiliting.
            See "Configuring Status Hilites" for further information.

          status_updates
            Allow  updates  to the status lines at the bottom of the screen
            (default true).

          suppress_alert
            This option may be set to a NetHack version level  to  suppress
            alert  notification messages about feature changes for that and
            prior versions (for example "suppress_alert:3.3.1").

          symset
            This option may be used to select one of the named symbol  sets
            found  within  "symbols"  to alter the symbols displayed on the
            screen.  Use "symset:default" to explicitly select the  default
            symbols.

          time
            Show  the  elapsed  game  time in turns on bottom line (default
            off).  Persistent.

          timed_delay
            When pausing momentarily for display effect, such as  with  ex-
            plosions  and  moving  objects, use a timer rather than sending
            extra characters to the screen.  (Applies to "tty" and "curses"
            interfaces  only; "X11" interface always uses a timer-based de-
            lay.  The default is on if configured into the program.)   Per-
            sistent.

          tombstone
            Draw a tombstone graphic upon your death (default on).  Persis-
            tent.

          toptenwin
            Put the ending display in a NetHack window instead of on stdout


          NetHack 3.7                                     December 28, 2022

            (default  off).  Setting this option makes the score list visi-
            ble when a windowing version of NetHack is  started  without  a
            parent  window,  but  it no longer leaves the score list around
            after game end on a terminal or emulating window.

          travel
            Allow the travel command via mouse click (default on).  Turning
            this option off will prevent the game from attempting unintend-
            ed moves if you make inadvertent mouse clicks on the  map  win-
            dow.   Does  not  affect traveling via the `_' ("#travel") com-
            mand.  Persistent.

          verbose
            Provide more commentary during the game (default on).   Persis-
            tent.

          whatis_coord
            When  using  the  `/' or `;' commands to look around on the map
            with autodescribe on, display coordinates  after  the  descrip-
            tion.   Also  works  in other situations where you are asked to
            pick a location.

            The possible settings are:

                 c - compass ("east" or "3s" or "2n,4w");
                 f - full compass ("east" or "3south" or "2north,4west");
                 m - map <x,y> (map column x=0 is not used);
                 s - screen [row,column] (row is offset to match tty usage);
                 n - none (no coordinates shown) [default].

            The whatis_coord option is also used with the "/m", "/M", "/o",
            and "/O" sub-commands of `/', where the "none" setting is over-
            ridden with "map".

          whatis_filter
            When getting a location on the map, and using the keys to cycle
            through  next and previous targets, allows filtering the possi-
            ble targets.

                 n - no filtering [default]
                 v - in view only
                 a - in same area only

            The area-filter tries  to  be  slightly  predictive--if  you're
            standing on a doorway, it will consider the area on the side of
            the door you were last moving towards.

            Filtering can also be changed when getting a location with  the
            "getpos.filter" key.

          whatis_menu
            When  getting  a  location on the map, and using a key to cycle
            through next and previous targets, use a menu instead to pick a
            target.  (default off)

          NetHack Guidebook                                              78



          whatis_moveskip
            When  getting a location on the map, and using shifted movement
            keys or meta-digit keys to fast-move, instead of moving 8 units
            at a time, move by skipping the same glyphs.  (default off)

          windowtype
            When the program has been built to support multiple interfaces,
            select which one to use, such as "tty" or  "X11"  (default  de-
            pends on build-time settings; use "#version" to check).  Cannot
            be set with the `O' command.

            When used, it should be the first option set  since  its  value
            might  enable  or disable the availability of various other op-
            tions.  For multiple lines in a configuration file, that  would
            be  the  first non-comment line.  For a comma-separated list in
            NETHACKOPTIONS or an OPTIONS line in a configuration file, that
            would be the rightmost option in the list.

          wizweight
            Augment object descriptions with their objects' weight (default
            off).  Debug mode only.

          zerocomp
            When writing out a save file, perform zero-comp compression  of
            the  contents.  Not all ports support zero-comp compression. It
            has no effect on reading an existing save file.

          9.5.  Window Port Customization options

               Here are explanations of the various options that  are  used
          to  customize  and  change  the characteristics of the windowtype
          that you have chosen.  Character strings that are too long may be
          truncated.   Not  all  window  ports will adjust for all settings
          listed here.  You can safely add any of  these  options  to  your
          configuration  file, and if the window port is capable of adjust-
          ing to suit your preferences, it will attempt to  do  so.  If  it
          can't  it will silently ignore it.  You can find out if an option
          is supported by the window port that you are currently  using  by
          checking to see if it shows up in the Options list.  Some options
          are dynamic and can be specified during the  game  with  the  `O'
          command.

          align_message
            Where  to align or place the message window (top, bottom, left,
            or right)

          align_status
            Where to align or place the status window (top,  bottom,  left,
            or right).

          ascii_map
            If  NetHack can, it should display the map using simple charac-
            ters (letters and punctuation) rather than tiles graphics.   In
            some  cases,  characters  can  be  augmented  with line-drawing

            symbols; use the symset option to select a symbol set  such  as
            DECgraphics or IBMgraphics if your display supports them.  Set-
            ting ascii_map to True forces tiled_map to be False.

          color
            If NetHack can, it should display color if it can for different
            monsters, objects, and dungeon features (default on).

          eight_bit_tty
            If  NetHack can, it should pass eight-bit character values (for
            example, specified with the traps option) straight  through  to
            your terminal (default off).

          font_map
            if NetHack can, it should use a font by the chosen name for the
            map window.

          font_menu
            If NetHack can, it should use a font by  the  chosen  name  for
            menu windows.

          font_message
            If NetHack can, it should use a font by the chosen name for the
            message window.

          font_status
            If NetHack can, it should use a font by the chosen name for the
            status window.

          font_text
            If  NetHack  can,  it  should use a font by the chosen name for
            text windows.

          font_size_map
            If NetHack can, it should use this size font for the  map  win-
            dow.

          font_size_menu
            If NetHack can, it should use this size font for menu windows.

          font_size_message
            If  NetHack  can,  it should use this size font for the message
            window.

          font_size_status
            If NetHack can, it should use this size  font  for  the  status
            window.

          font_size_text
            If NetHack can, it should use this size font for text windows.

          fullscreen
            If  NetHack can, it should try and display on the entire screen
            rather than in a window.

          guicolor
            Use color text and/or highlighting attributes  when  displaying
            some  non-map data (such as menu selector letters).  Curses in-
            terface only; default is on.

          large_font
            If NetHack can, it should use a large font.

          map_mode
            If NetHack can, it should display the map in the manner  speci-
            fied.

          player_selection
            If  NetHack  can, it should pop up dialog boxes, or use prompts
            for character selection.

          popup_dialog
            If NetHack can, it should pop up dialog boxes for input.

          preload_tiles
            If NetHack can, it should preload tiles into memory.  For exam-
            ple,  in  the  protected  mode  MS-DOS version, control whether
            tiles get pre-loaded into RAM at the start of the game.   Doing
            so  enhances  performance  of  the tile graphics, but uses more
            memory. (default on).  Cannot be set with the `O' command.

          scroll_amount
            If NetHack can, it should scroll the display by this number  of
            cells when the hero reaches the scroll_margin.

          scroll_margin
            If  NetHack  can, it should scroll the display when the hero or
            cursor is this number of cells away from the edge of  the  win-
            dow.

          selectsaved
            If  NetHack  can,  it  should  display a menu of existing saved
            games for the player to choose from at game startup, if it can.
            Not all ports support this option.

          softkeyboard
            Display  an  onscreen  keyboard.   Handhelds are most likely to
            support this option.

          splash_screen
            If NetHack can, it should display an opening splash screen when
            it starts up (default yes).

          statuslines
            Number  of  lines for traditional below-the-map status display.
            Acceptable values are 2 and 3 (default is 2).

            When set to 3, the tty interface moves some fields  around  and
            mainly  shows  status  conditions on their own line.  A display


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              81



            capable of showing at least 25 lines is recommended.  The value
            can be toggled back and forth during the game with the `O' com-
            mand.

            The curses interface does likewise if the  align_status  option
            is  set  to  top  or bottom but ignores statuslines when set to
            left or right.

            The Qt interface already displays more than 3 lines for  status
            so  uses  the statuslines value differently.  A value of 3 ren-
            ders status in the Qt interface's  original  format,  with  the
            status window spread out vertically.  A value of 2 makes status
            be slightly condensed, moving some fields to different lines to
            eliminate  one  whole  line,  reducing  the height needed.  (If
            NetHack has been built using a version of Qt older than qt-5.9,
            statuslines  can only be set in the run-time configuration file
            or via NETHACKOPTIONS, not during play with the `O' command.)

          term_cols  and

          term_rows
            Curses interface only.  Number of columns and rows to  use  for
            the display.  Curses will attempt to resize to the values spec-
            ified but will settle for smaller sizes if they  are  too  big.
            Default is the current window size.

          tile_file
            Specify  the  name  of an alternative tile file to override the
            default.

            Note: the X11 interface uses X resources rather than  NetHack's
            options  to select an alternate tile file.  See NetHack.ad, the
            sample X "application defaults" file.

          tile_height
            Specify the preferred height of each tile  in  a  tile  capable
            port.

          tile_width
            Specify the preferred width of each tile in a tile capable port

          tiled_map
            If  NetHack can, it should display the map using tiles graphics
            rather than simple characters (letters and punctuation,  possi-
            bly  augmented  by line-drawing symbols).  Setting tiled_map to
            True forces ascii_map to be False.

          use_darkgray
            Use bold black instead of blue for black glyphs (TTY only).

          use_inverse
            If NetHack can, it should display inverse when the game  speci-
            fies it.



          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              82



          vary_msgcount
            If  NetHack can, it should display this number of messages at a
            time in the message window.

          windowborders
            Whether to draw boxes around  the  map,  status  area,  message
            area,  and  persistent inventory window if enabled.  Curses in-
            terface only.  Acceptable values are

                 0 - off, never show borders
                 1 - on, always show borders
                 2 - auto, on if display is at least (24+2)x(80+2) [default]
                 3 - on, except forced off for perm_invent
                 4 - auto, except forced off for perm_invent

            (The 26x82 size threshold for `2' refers to number of rows  and
            columns  of  the  display.   A  width  of  at least 110 columns
            (80+2+26+2) is needed to show borders if align_status is set to
            left or right.)

            The  persistent  inventory window, when enabled, can grow until
            it is too big to fit on most displays, resulting in  truncation
            of  its  contents.  If borders are forced on (1) or the display
            is big enough to show them (2), setting the value to 3 or 4 in-
            stead  will  keep borders for the map, message, and status win-
            dows but have room for two additional lines of  inventory  plus
            widen each inventory line by two columns.

          windowcolors
            If  NetHack  can,  it should display windows with the specified
            foreground/background colors.  Windows GUI only.  The format is

               OPTION=windowcolors:wintype foreground/background

               where wintype is one  of  "menu",  "message",  "status",  or
          "text",  and foreground and background are colors, either a hexa-
          decimal \'#rrggbb', one of the named colors (black,  red,  green,
          brown,  blue, magenta, cyan, orange, brightgreen, yellow, bright-
          blue, brightmagenta, brightcyan, white, trueblack, gray,  purple,
          silver,  maroon,  fuchsia, lime, olive, navy, teal, aqua), or one
          of Windows UI colors (activeborder, activecaption,  appworkspace,
          background,  btnface,  btnshadow, btntext, captiontext, graytext,
          greytext, highlight, highlighttext, inactiveborder,  inactivecap-
          tion,  menu,  menutext,  scrollbar,  window, windowframe, window-
          text).

          wraptext
            If NetHack can, it should wrap long lines of text if they don't
            fit in the visible area of the window.

          9.6.  Platform-specific Customization options

               Here  are  explanations of options that are used by specific
          platforms or ports to customize and change the port behavior.


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              83



          altkeyhandling
            Select an alternate way to handle keystrokes (Win32 tty NetHack
            only).   The  name  of  the  handling type is one of "default",
            "ray", "340".

          altmeta
            On systems where this option is available, it  can  be  set  to
            tell NetHack to convert a two character sequence beginning with
            ESC into a meta-shifted version of the  second  character  (de-
            fault off).

            This  conversion is only done for commands, not for other input
            prompts.  Note that typing one or more digits as a count prefix
            prior  to  a command--preceded by n if the number_pad option is
            set--is also subject to this conversion, so attempting to abort
            the  count by typing ESC will leave NetHack waiting for another
            character to complete the two character sequence.  Type a  sec-
            ond  ESC to finish cancelling such a count.  At other prompts a
            single ESC suffices.

          BIOS
            Use BIOS calls to update the screen display quickly and to read
            the  keyboard  (allowing  the use of arrow keys to move) on ma-
            chines with an IBM PC compatible BIOS ROM (default  off,  OS/2,
            PC, and ST NetHack only).

          flush
            (default off, Amiga NetHack only).

          MACgraphics
            (default on, Mac NetHack only).

          page_wait
            (default on, Mac NetHack only).

          rawio
            Force  raw (non-cbreak) mode for faster output and more bullet-
            proof input (MS-DOS sometimes treats `^P' as a  printer  toggle
            without  it)  (default  off,  OS/2,  PC,  and ST NetHack only).
            Note:  DEC Rainbows hang if this is turned on.  Cannot  be  set
            with the `O' command.

          subkeyvalue
            (Win32  tty  NetHack  only).  May be used to alter the value of
            keystrokes that the operating system returns to NetHack to help
            compensate  for international keyboard issues.  OPTIONS=subkey-
            value:171/92 will return 92 to NetHack, if 171  was  originally
            going to be returned.  You can use multiple subkeyvalue assign-
            ments in the configuration file if needed.  Cannot be set  with
            the `O' command.

          video
            Set the video mode used (PC NetHack only).  Values are "autode-
            tect", "default", "vga", or "vesa".  Setting "vesa" will  cause


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              84



            the game to display tiles, using the full capability of the VGA
            hardware.  Setting "vga" will cause the game to display  tiles,
            fixed  at  640x480 in 16 colors, a mode that is compatible with
            all VGA hardware. Third party tilesets will probably not  work.
            Setting  "autodetect"  attempts "vesa", then "vga", and finally
            sets "default" if neither of those modes works.  Cannot be  set
            with the `O' command.

          video_height
            Set   the   VGA  mode  resolution  height  (MS-DOS  only,  with
            video:vesa)

          video_width
            Set  the  VGA  mode  resolution  width   (MS-DOS   only,   with
            video:vesa)

          videocolors
            Set  the  color  palette for PC systems using NO_TERMS (default
            4-2-6-1-5-3-15-12-10-14-9-13-11, (PC NetHack only).  The  order
            of   colors   is   red,  green,  brown,  blue,  magenta,  cyan,
            bright.white, bright.red,  bright.green,  yellow,  bright.blue,
            bright.magenta,  and  bright.cyan.   Cannot be set with the `O'
            command.

          videoshades
            Set the intensity level of the three gray scales available (de-
            fault dark normal light, PC NetHack only).  If the game display
            is difficult to read, try adjusting these scales; if this  does
            not  correct  the  problem, try !color.  Cannot be set with the
            `O' command.

          9.7.  Regular Expressions

               Regular expressions are normally POSIX extended regular  ex-
          pressions.  It is possible to compile NetHack without regular ex-
          pression support on a platform where there is no regular  expres-
          sion  library.  While this is not true of any modern platform, if
          your NetHack was built this way, patterns are instead  glob  pat-
          terns. This applies to Autopickup exceptions, Message types, Menu
          colors, and User sounds.

          9.8.  Configuring Autopickup Exceptions

               You can further refine the behavior of the autopickup option
          beyond what is available through the pickup_types option.

               By  placing autopickup_exception lines in your configuration
          file, you can define patterns to be  checked  when  the  game  is
          about to autopickup something.

          autopickup_exception
            Sets  an  exception  to the pickup_types option.  The autopick-
            up_exception option should be followed by a regular  expression
            to  be  used as a pattern to match against the singular form of


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              85



            the description of an object at your location.

            In addition, some characters are treated specially if they  oc-
            cur as the first character in the pattern, specifically:

                 < - always pickup an object that matches rest of pattern;
                 > - never pickup an object that matches rest of pattern.

            The  autopickup_exception  rules  are processed in the order in
            which they appear in your configuration file, thus  allowing  a
            later rule to override an earlier rule.

            Exceptions  can  be  set with the `O' command, but because they
            are not included in your configuration file, they won't  be  in
            effect  if you save and then restore your game.  autopickup_ex-
            ception rules and not saved with the game.

          Here are some examples:

                 autopickup_exception="<*arrow"
                 autopickup_exception=">*corpse"
                 autopickup_exception=">* cursed*"

               The first example above will result  in  autopickup  of  any
          type  of  arrow.   The second example results in the exclusion of
          any corpse from autopickup.  The last example results in the  ex-
          clusion of items known to be cursed from autopickup.

          9.9.  Changing Key Bindings

               It  is  possible  to change the default key bindings of some
          special commands, menu accelerator keys, and  extended  commands,
          by  using BIND stanzas in the configuration file.  Format is key,
          followed by the command to bind to, separated by  a  colon.   The
          key can be a single character ("x"), a control key ("^X", "C-x"),
          a meta key ("M-x"), a mouse  button,  or  a  three-digit  decimal
          ASCII code.

               For example:

               BIND=^X:getpos.autodescribe
               BIND=\:menu_first_page
               BIND=v:loot

          Extended command keys
            You  can  bind multiple keys to the same extended command.  Un-
            bind a key by using "nothing" as the extended command  to  bind
            to.   You  can  also bind the "<esc>", "<enter>", and "<space>"
            keys.

          Menu accelerator keys
            The menu control or accelerator keys can also  be  rebound  via
            OPTIONS  lines  in the configuration file.  You cannot bind ob-
            ject symbols or selection letters into menu accelerators.  Some


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              86



            interfaces only support some of the menu accelerators.

          Mouse buttons
            You can bind "mouse1" or "mouse2" to "nothing", "therecmdmenu",
            "clicklook", or "mouseaction".

          Special command keys
            Below are the special commands you can rebind.   Some  of  them
            can  be  bound to same keys with no problems, others are in the
            same "context", and if bound to same keys, only  one  of  those
            commands  will be available.  Special command can only be bound
            to a single key.

          count
            Prefix key to start a count, to  repeat  a  command  this  many
            times.  With number_pad only.  Default is `n'.

          getdir.help
            When  asked for a direction, the key to show the help.  Default
            is `?'.

          getdir.mouse
            When asked for a direction, the key  to  initiate  a  simulated
            mouse  click.  You will be asked to pick a location.  Use move-
            ment keystrokes to move the cursor around the  map,  then  type
            the  getpos.pick.once  key (default `,') or the getpos.pick key
            (default `.')  to finish as  if  performing  a  left  or  right
            click.   Only useful when using the #therecmdmenu command.  De-
            fault is `_'.

          getdir.self
            When asked for a direction, the key to  target  yourself.   De-
            fault is `.'.

          getdir.self2
            When  asked  for  a direction, an alternate key to target your-
            self.  Default is `s'.

          getpos.autodescribe
            When asked for a location, the key to toggle autodescribe.  De-
            fault is `#'.

          getpos.all.next
            When asked for a location, the key to go to next closest inter-
            esting thing.  Default is `a'.

          getpos.all.prev
            When asked for a location, the key to go  to  previous  closest
            interesting thing.  Default is `A'.

          getpos.door.next
            When  asked  for a location, the key to go to next closest door
            or doorway.  Default is `d'.

          NetHack Guidebook                                              87



          getpos.door.prev
            When asked for a location, the key to go  to  previous  closest
            door or doorway.  Default is `D'.

          getpos.help
            When  asked  for  a location, the key to show help.  Default is
            `?'.

          getpos.mon.next
            When asked for a location, the key to go to next  closest  mon-
            ster.  Default is `m'.

          getpos.mon.prev
            When  asked  for  a location, the key to go to previous closest
            monster.  Default is `M'.

          getpos.obj.next
            When asked for a location, the key to go to  next  closest  ob-
            ject.  Default is `o'.

          getpos.obj.prev
            When  asked  for  a location, the key to go to previous closest
            object.  Default is `O'.

          getpos.menu
            When asked for a location, and using one of the next or  previ-
            ous  keys  to  cycle through targets, toggle showing a menu in-
            stead.  Default is `!'.

          getpos.moveskip
            When asked for a location, and using the shifted movement  keys
            or  meta-digit  keys  to fast-move around, move by skipping the
            same glyphs instead of by 8 units.  Default is `*'.

          getpos.filter
            When asked for a location, change the filtering mode when using
            one  of  the  next  or  previous keys to cycle through targets.
            Toggles between no filtering, in view only,  and  in  the  same
            area only.  Default is `"'.

          getpos.pick
            When  asked for a location, the key to choose the location, and
            possibly ask for more info.  When simulating a mouse click  af-
            ter  being  asked for a direction (see getdir.mouse above), the
            key to use to respond as right click.  Default is `.'.

          getpos.pick.once
            When asked for a location, the key to choose the location,  and
            skip asking for more info.  When simulating a mouse click after
            being asked for a direction, the key to respond as left  click.
            Default is `,'.

            asking for more info, and exit the location asking  loop.   De-
            fault is `;'.

          getpos.pick.verbose
            When  asked for a location, the key to choose the location, and
            show more info without asking.  Default is `:'.

          getpos.self
            When asked for a location, the key to go to your location.  De-
            fault is `@'.

          getpos.unexplored.next
            When  asked for a location, the key to go to next closest unex-
            plored location.  Default is `x'.

          getpos.unexplored.prev
            When asked for a location, the key to go  to  previous  closest
            unexplored location.  Default is `X'.

          getpos.valid
            When  asked  for a location, the key to go to show valid target
            locations.  Default is `$'.

          getpos.valid.next
            When asked for a location, the key to go to next closest  valid
            location.  Default is `z'.

          getpos.valid.prev
            When  asked  for  a location, the key to go to previous closest
            valid location.  Default is `Z'.

          9.10.  Configuring Message Types

               You can change the way the messages are shown in the message
          area, when the message matches a user-defined pattern.

               In  general,  the configuration file entries to describe the
          message types look like this: MSGTYPE=type "pattern"

          type    - how the message should be shown;
          pattern - the pattern to match.

            The pattern should be a regular expression.

            Allowed types are:

            show  - show message normally;
            hide  - never show the message;
            stop  - wait for user with more-prompt;
            norep - show the message once, but not again if no  other  mes-
                    sage is shown in between.

            Here's  an  example  of  message types using NetHack's internal
            pattern matching facility:


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              89



                 MSGTYPE=stop "You feel hungry."
                 MSGTYPE=hide "You displaced *."

            specifies that whenever a message "You feel hungry"  is  shown,
            the  user  is prompted with more-prompt, and a message matching
            "You displaced <something>." is not shown at all.

            The order of the defined MSGTYPE lines is important;  the  last
            matching  rule  is used. Put the general case first, exceptions
            below them.

          9.11.  Configuring Menu Colors

               Some platforms allow you to define colors used in menu lines
          when  the  line matches a user-defined pattern.  At this time the
          tty, curses, win32tty and win32gui interfaces support this.

               In general, the configuration file entries to  describe  the
          menu color mappings look like this:

               MENUCOLOR="pattern"=color&attribute

                 pattern    - the pattern to match;
                 color      - the  color to use for lines matching the pat-
                              tern;
                 attribute  - the attribute to use for lines  matching  the
                              pattern.  The  attribute  is optional, and if
                              left out, you must also leave out the preced-
                              ing  ampersand.   If no attribute is defined,
                              no attribute is used.

            The pattern should be a regular expression.

            Allowed colors are black, red,  green,  brown,  blue,  magenta,
            cyan,  gray, orange, light-green, yellow, light-blue, light-ma-
            genta, light-cyan, and white.  And no-color, the default  fore-
            ground  color,  which  isn't necessarily the same as any of the
            other colors.

            Allowed attributes are  none,  bold,  dim,  italic,  underline,
            blink,  and  inverse.   "Normal" is a synonym for "none".  Note
            that the platform used may interpret the attributes any way  it
            wants.

            Here's  an example of menu colors using NetHack's internal pat-
            tern matching facility:

                 MENUCOLOR="* blessed *"=green
                 MENUCOLOR="* cursed *"=red
                 MENUCOLOR="* cursed *(being worn)"=red&underline

            specifies that any menu line with " blessed " contained  in  it
            will  be  shown  in  green color, lines with " cursed " will be
            shown in red, and lines with  " cursed "  followed  by  "(being


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              90



            worn)"  on  the same line will be shown in red color and under-
            lined.  You can have multiple MENUCOLOR entries in your config-
            uration  file,  and the last MENUCOLOR line that matches a menu
            line will be used for the line.

               Note that if you intend to have one or more color specifica-
          tions  match " uncursed ", you will probably want to turn the im-
          plicit_uncursed option off so that all items known to be uncursed
          are actually displayed with the "uncursed" description.

          9.12.  Configuring User Sounds

               Some  platforms allow you to define sound files to be played
          when a message that matches a user-defined pattern  is  delivered
          to the message window.  At this time the Qt port and the win32tty
          and win32gui ports support the use of user sounds.

               The following configuration file  entries  are  relevant  to
          mapping user sounds to messages:

          SOUNDDIR
            The directory that houses the sound files to be played.

          SOUND
            An  entry  that  maps  a sound file to a user-specified message
            pattern.  Each SOUND entry is broken down  into  the  following
            parts:

            MESG        - message window mapping (the only one supported in
                          3.7);
            msgtype     - optional; message type to use,  see  "Configuring
                          Message Types"
            pattern     - the pattern to match;
            sound file  - the sound file to play;
            volume      - the  volume  to  be  set  while playing the sound
                          file;
            sound index - optional; the  index  corresponding  to  a  sound
                          file.

            The pattern should be a POSIX extended regular expression.

               For example:

               SOUNDDIR=C:\nethack\sounds
               SOUND=MESG "This door is locked" "lock.wav" 100
               SOUND=MESG hide "^You miss the " "swing.wav" 75

          9.13.  Configuring Status Hilites

               Your copy of NetHack may have been compiled with support for
          "Status Hilites".  If so, you can customize your game display  by
          setting thresholds to change the color or appearance of fields in
          the status display.



          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              91



               The format for defining status colors is:

          OPTION=hilite_status:field-name/behavior/color&attributes

               For example, the following line in your  configuration  file
          will  cause  the  hitpoints  field to display in the color red if
          your hitpoints drop to or below a threshold of 30%:

          OPTION=hilite_status:hitpoints/<=30%/red/normal

          (That example is actually specifying red&normal for <=30% and no-
          color&normal for >30%.)

               For  another  example, the following line in your configura-
          tion file will cause wisdom to be displayed red if it  drops  and
          green if it rises:

          OPTION=hilite_status:wisdom/down/red/up/green

               Allowed  colors are black, red, green, brown, blue, magenta,
          cyan, gray, orange, light-green, yellow, light-blue, light-magen-
          ta,  light-cyan,  and  white.   And "no-color", the default fore-
          ground color on the display, which is not necessarily the same as
          black or white or any of the other colors.

               Allowed  attributes  are  none, bold, dim, underline, blink,
          and inverse.  "Normal" is a synonym for "none"; they  should  not
          be used in combination with any of the other attributes.

               To specify both a color and an attribute, use `&' to combine
          them.  To specify multiple attributes, use `+' to combine  those.
          For example: "magenta&inverse+dim".

               Note  that  the  display may substitute or ignore particular
          attributes depending upon its capabilities, and  in  general  may
          interpret  the attributes any way it wants.  For example, on some
          display systems a request for bold might yield blink or vice ver-
          sa.  On others, issuing an attribute request while another is al-
          ready set up will replace the earlier attribute rather than  com-
          bine  with  it.   Since NetHack issues attribute requests sequen-
          tially (at least with the tty interface) rather than all at once,
          the only way a situation like that can be controlled is to speci-
          fy just one attribute.

               You can  adjust  the  appearance  of  the  following  status
          fields:
                     title       dungeon-level   experience-level
                    strength         gold           experience
                   dexterity       hitpoints            HD
                  constitution   hitpoints-max         time
                  intelligence       power            hunger
                     wisdom        power-max     carrying-capacity
                    charisma      armor-class        condition



          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              92



                   alignment                           score

            The  pseudo-field  "characteristics" can be used to set all six
            of Str, Dex, Con, Int, Wis, and Cha  at  once.   "HD"  is  "hit
            dice",  an  approximation  of  experience  level displayed when
            polymorphed.  "experience", "time", and "score" are  condition-
            ally displayed depending upon your other option settings.

            Instead  of  a behavior, "condition" takes the following condi-
            tion flags: stone, slime,  strngl,  foodpois,  termill,  blind,
            deaf,  stun, conf, hallu, lev, fly, and ride.  You can use "ma-
            jor_troubles" as an  alias  for  stone  through  termill,  "mi-
            nor_troubles" for blind through hallu, "movement" for lev, fly,
            and ride, and "all" for every condition.

            Allowed behaviors are "always", "up", "down", "changed", a per-
            centage or absolute number threshold, or text to match against.

               * "always" will set the default attributes for that field.

               * "up",  "down"  set the field attributes for when the field
                 value changes upwards or downwards.  This attribute  times
                 out after statushilites turns.

               * "changed" sets the field attribute for when the field val-
                 ue changes.  This attribute times out after  statushilites
                 turns.   (If a field has both a "changed" rule and an "up"
                 or "down" rule which matches a change in the field's  val-
                 ue, the "up" or "down" one takes precedence.)

               * percentage  sets  the field attribute when the field value
                 matches the percentage.  It is specified as a  number  be-
                 tween  0  and 100, followed by `%' (percent sign).  If the
                 percentage is prefixed with `<=' or `>=', it also  matches
                 when  value  is below or above the percentage.  Use prefix
                 `<' or `>' to match when strictly below  or  above.   (The
                 numeric  limit  is  relaxed  slightly  for those: >-1% and
                 <101% are allowed.)  Only four fields  support  percentage
                 rules.    Percentages  for  "hitpoints"  and  "power"  are
                 straightforward; they're based on the corresponding  maxi-
                 mum  field.   Percentage  highlight rules are also allowed
                 for "experience level" and "experience points" (valid when
                 the showexp option is enabled).  For those, the percentage
                 is based on the progress from the start of the current ex-
                 perience level to the start of the next level.  So if lev-
                 el 2 starts at 20 points and level 3 starts at 40  points,
                 having  30  points  is  50% and 35 points is 75%.  100% is
                 unattainable for experience because you'll  gain  a  level
                 and the calculations will be reset for that new level, but
                 a rule for =100% is allowed and matches the  special  case
                 of being exactly 1 experience point short of the next lev-
                 el.

          NetHack Guidebook                                              93



               * absolute value sets the attribute  when  the  field  value
                 matches  that number.  The number must be 0 or higher, ex-
                 cept for "armor-class' which allows negative  values,  and
                 may  optionally be preceded by `='.  If the number is pre-
                 ceded by `<=' or `>=' instead, it also matches when  value
                 is  below  or  above.   If  the prefix is `<' or `>', only
                 match when strictly above or below.

               * text match sets the attribute when the field value matches
                 the  text.  Text matches can only be used for "alignment",
                 "carrying-capacity", "hunger", "dungeon-level",  and  "ti-
                 tle".   For  title,  only the role's rank title is tested;
                 the character's name is ignored.

               The in-game options menu can help you determine the  correct
          syntax for a configuration file.

               The  whole  feature  can  be disabled by setting option sta-
          tushilites to 0.

               Example hilites:

               OPTION=hilite_status: gold/up/yellow/down/brown
               OPTION=hilite_status: characteristics/up/green/down/red
               OPTION=hilite_status: hitpoints/100%/gray&normal
               OPTION=hilite_status: hitpoints/<100%/green&normal
               OPTION=hilite_status: hitpoints/<66%/yellow&normal
               OPTION=hilite_status: hitpoints/<50%/orange&normal
               OPTION=hilite_status: hitpoints/<33%/red&bold
               OPTION=hilite_status: hitpoints/<15%/red&inverse
               OPTION=hilite_status: condition/major/orange&inverse
               OPTION=hilite_status: condition/lev+fly/red&inverse

          9.14.  Modifying NetHack Symbols

               NetHack can load entire symbol sets from the symbol file.

               The options that are used to select a particular symbol  set
          from the symbol file are:

          symset
            Set the name of the symbol set that you want to load.

          roguesymset

               You can also override one or more symbols using the  SYMBOLS
          and  ROGUESYMBOLS configuration file options.  Symbols are speci-

          value  string  in conventional C fashion.  This means that \ is a
          prefix to take the following character literally.  Thus  \  needs
          to  be represented as \\.  The special prefix form \m switches on
          the meta bit in the symbol value, and the  ^  prefix  causes  the

          Notes:

          * Several symbols in this table appear to be blank.  They are the
            space character, except for S_pet_override and  S_hero_override
            which  don't have any default value and can only be used if en-
            abled in the "sysconf" file.

          * S_rock is misleadingly  named;  rocks  and  stones  use  S_gem.
            Statues  and boulders are the rock being referred to, but since
            version 3.6.0, statues are displayed as the  monster  they  de-
            pict.   So S_rock is only used for boulders and not used at all
            if overridden by the more specific S_boulder.

          9.15.  Customizing Map Glyph Representations Using Unicode

               If your platform or terminal supports the display  of  UTF-8
          character  sequences,  you can customize your game display by as-
          signing Unicode codepoint values  and  red-green-blue  colors  to
          glyph  representations.  The  customizations can be specified for
          use with a symset that has a UTF8 handler within the symbols file
          such as the enhanced1 set, or individually within your nethack.rc
          file.


               The format for defining a glyph representation is:



          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                              98



          OPTIONS=glyph:glyphidU+nnnn/R-G-B

               The window port that is active needs to provide support  for
          displaying  UTF-8 character sequences and explicit red-green-blue
          colors in order for the glyph representation to be visible.   For
          example, the following line in your configuration file will cause
          the glyph representation for glyphid G_pool to use Unicode  code-
          point U+224B and the color represented by R-G-B value 0-0-160

          OPTIONS=glyph:G_pool/U+224B/0-0-160

          The  list  of  acceptable  glyphid's  can  be produced by nethack
          --dumpglyphids.  Individual NetHack glyphs can be specified using
          the  G_  prefix,  or  you  can use an S_ symbol for a glyphid and
          store the custom representation for all NetHack glyphs that would
          map to that particular symbol.

          You  will  need  to select a symset with a UTF8 handler to enable
          the display of the customizations, such as the Enhanced symset.

          9.16.  Configuring NetHack for Play by the Blind

               NetHack can be set up to use only standard ASCII  characters
          for  making maps of the dungeons. This makes even the MS-DOS ver-
          sions of NetHack (which use special  line-drawing  characters  by
          default) completely accessible to the blind who use speech and/or
          Braille access technologies.  Players will require a good working
          knowledge of their screen-reader's review features, and will have
          to know how to navigate horizontally and vertically character  by
          character.  They  will also find the search capabilities of their
          screen-readers to be quite valuable. Be certain to  examine  this
          Guidebook before playing so you have an idea what the screen lay-
          out is like. You'll also need to be able to locate the PC cursor.
          It  is  always  where your character is located. Merely searching
          for an @-sign will not always find your character since there are
          other  humanoids represented by the same sign. Your screen-reader
          should also have a function which gives you the row and column of
          your review cursor and the PC cursor.  These co-ordinates are of-
          ten useful in giving players a better sense of the overall  loca-
          tion of items on the screen.

               NetHack  can  also  be compiled with support for sending the
          game messages to an external program, such  as  a  text-to-speech
          synthesizer.   If the "#version" extended command shows "external
          program as a message handler", your  NetHack  has  been  compiled
          with the capability.  When compiling NetHack from source on Linux
          and other POSIX systems, define MSGHANDLER to enable it.  To  use
          the  capability,  set the environment variable NETHACK_MSGHANDLER
          to an executable, which will be executed with the game message as
          the program's only parameter.

               The  most  crucial settings to make the game more accessible
          are:

          NetHack Guidebook                                              99



          symset:plain
            Load a symbol set appropriate for use by blind players.

          menustyle:traditional
            This will assist in the interface to speech synthesizers.

          nomenu_overlay
            Show menus on a cleared screen and aligned to the left edge.

          number_pad
            A lot of speech access programs use the  number-pad  to  review
            the screen.  If this is the case, disable the number_pad option
            and use the traditional Rogue-like commands.

          paranoid_confirmation:swim
            Prevent walking into water or lava.

          autodescribe
            Automatically describe the terrain under the cursor  when  tar-
            geting.

          mention_walls
            Give  feedback  messages  when  walking  towards a wall or when
            travel command was interrupted.

          whatis_coord:compass
            When targeting with cursor, describe the cursor  position  with
            coordinates relative to your character.

          whatis_filter:area
            When  targeting  with cursor, filter possible locations so only
            those in the same area (eg. same room, or  same  corridor)  are
            considered.

          whatis_moveskip
            When  targeting  with cursor and using fast-move, skip the same
            glyphs instead of moving 8 units at a time.

          nostatus_updates
            Prevent updates to the  status  lines  at  the  bottom  of  the
            screen,  if  your screen-reader reads those lines. The same in-
            formation can be seen via the "#attributes" command.

          9.17.  Global Configuration for System Administrators

               If NetHack is compiled with the SYSCF option, a  system  ad-
          ministrator  should set up a global configuration; this is a file
          in the same format as the traditional per-user configuration file
          (see above).  This file should be named sysconf and placed in the
          same directory as the other NetHack support files.   The  options
          recognized in this file are listed below.  Any option not set us-
          es a compiled-in default (which may not be appropriate  for  your
          system).

          NetHack Guidebook                                             100



            WIZARDS = A  space-separated list of user names who are allowed
            to play in debug mode (commonly referred to as wizard mode).  A
            value of a single asterisk (*) allows anyone to start a game in
            debug mode.

            SHELLERS = A list of users who are allowed to use the shell es-
            cape command (!).  The syntax is the same as WIZARDS.

            EXPLORERS = A  list of users who are allowed to use the explore
            mode.  The syntax is the same as WIZARDS.

            MAXPLAYERS = Limit the maximum number of games that can be run-
            ning at the same time.

            SAVEFORMAT = A list of up to two save file formats separated by
            space.  The first format in the list will written  as  well  as
            read.  The  second  format will be read only if no save file in
            the first format exists.  Valid choices  are  "historical"  for
            binary  writing of entire structs, "lendian" for binary writing
            of each field in little-endian order, "ascii" for  writing  the
            save file content in ascii text.

            BONESFORMAT = A  list of up to two bones file formats separated
            by space.  The first format in the list will written as well as
            read.  The second format will be read only if no bones files in
            the first format exist.  Valid choices are "historical" for bi-
            nary writing of entire structs, "lendian" for binary writing of
            each field in little-endian  order,  "ascii"  for  writing  the
            bones file content in ascii text.

            SUPPORT = A  string explaining how to get local support (no de-
            fault value).

            RECOVER = A string explaining how to recover  a  game  on  this
            system (no default value).

            SEDUCE = 0  or 1 to disable or enable, respectively, the SEDUCE
            option.  When disabled, incubi and succubi behave like nymphs.

            CHECK_PLNAME = Setting this to 1 will make the EXPLORERS,  WIZ-
            ARDS, and SHELLERS check for the player name instead of the us-
            er's login name.

            CHECK_SAVE_UID = 0 or 1 to disable or enable, respectively, the
            UID  (used  identification  number) checking for save files (to
            verify that the user who is  restoring  is  the  same  one  who
            saved).

               The following four options affect the score file:

            PERSMAX = Maximum number of entries for one person.

            ENTRYMAX = Maximum number of entries in the score file.



          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                             101



            POINTSMIN = Minimum  number  of  points  to get an entry in the
            score file.

            PERS_IS_UID = 0 or 1 to use user names or numeric userids,  re-
            spectively, to identify unique people for the score file.

            HIDEUSAGE = 0  or  1 to control whether the help menu entry for
            command line usage is shown or suppressed.

            MAX_STATUENAME_RANK = Maximum number of score file  entries  to
            use for random statue names (default is 10).

            ACCESSIBILITY = 0  or 1 to disable or enable, respectively, the
            ability for players to set S_pet_override  and  S_hero_override
            symbols in their configuration file.

            PORTABLE_DEVICE_PATHS = 0  or  1 Windows OS only, the game will
            look for all of its external files, and write  to  all  of  its
            output  files  in  one  place rather than at the standard loca-
            tions.

            DUMPLOGFILE = A  filename  where  the  end-of-game  dumplog  is
            saved.   Not defining this will prevent dumplog from being cre-
            ated.  Only available if your game is  compiled  with  DUMPLOG.
            Allows the following placeholders:

                %% - literal `%'
                %v - version (eg. "3.7.0-0")
                %u - game UID
                %t - game start time, UNIX timestamp format
                %T - current time, UNIX timestamp format
                %d - game start time, YYYYMMDDhhmmss format
                %D - current time, YYYYMMDDhhmmss format
                %n - player name
                %N - first character of player name

            LIVELOG = A  bit-mask of types of events that should be written
            to the livelog file if one is present.  The sample sysconf file
            accompanying  the  program  contains  a comment which lists the
            meaning of the various bits used.  Intended for server  systems
            supporting  simultaneous play by multiple players (to be clear,
            each one running a separate single player game), for displaying
            their game progress to observers.  Only relevant if the program
            was built with LIVELOG enabled.  When available, it  should  be
            left  commented out on single player installations because over
            time the file could grow to be extremely large unless it is ac-
            tively maintained.

          10.  Scoring

               NetHack  maintains  a  list  of the top scores or scorers on
          your machine, depending on how it is set up.  In the latter case,
          each  account  on the machine can post only one non-winning score
          on this list.  If you score higher  than  someone  else  on  this


          NetHack 3.7                                     December 28, 2022





          NetHack Guidebook                                             102



          list,  or better your previous score, you will be inserted in the
          proper place under your current name.  How many scores  are  kept
          can also be set up when NetHack is compiled.

               Your  score  is  chiefly  based upon how much experience you
          gained, how much loot you accumulated, how deep you explored, and
          how the game ended.  If you quit the game, you escape with all of
          your gold intact.  If, however, you get killed in  the  Mazes  of
          Menace, the guild will only hear about 90% of your gold when your
          corpse is discovered (adventurers  have  been  known  to  collect
          finder's  fees).   So, consider whether you want to take one last
          hit at that monster and possibly live,  or  quit  and  stop  with
          whatever  you  have.  If you quit, you keep all your gold, but if
          you swing and live, you might find more.

               If you just want to see what the current  top  players/games
          list is, you can type nethack -s all on most versions.

          11.  Explore mode

               NetHack  is  an intricate and difficult game.  Novices might
          falter in fear, aware of their ignorance of the means to survive.
          Well, fear not.  Your dungeon comes equipped with an "explore" or
          "discovery" mode that enables you to  keep  old  save  files  and
          cheat  death, at the paltry cost of not getting on the high score
          list.

               There are two ways of enabling  explore  mode.   One  is  to
          start  the game with the -X command-line switch or with the play-
          mode:explore option.  The other is to  issue  the  "#exploremode"
          extended  command while already playing the game.  Starting a new
          game in explore mode provides your character with a wand of wish-
          ing  in  initial  inventory; switching during play does not.  The
          other benefits of explore mode are left for the trepid reader  to
          discover.

          11.1.  Debug mode

               Debug mode, also known as wizard mode, is undocumented aside
          from this brief description and the  various  "debug  mode  only"
          commands  listed  among the command descriptions.  It is intended
          for tracking down problems within the program rather than to pro-
          vide  god-like  powers to your character, and players who attempt
          debugging are expected to figure out how to  use  it  themselves.
          It  is  initiated  by  starting the game with the -D command-line
          switch or with the playmode:debug option.

               For some systems, the player must be logged in under a  par-
          ticular  user  name  to be allowed to use debug mode; for others,
          the hero must be given a particular character name  (but  may  be
          any  role;  there's  no  connection between "wizard mode" and the
          Wizard role).  Attempting to start a game in debug mode when  not
          allowed  or  not available will result in falling back to explore
          mode instead.

          12.  Credits

               The original hack game was  modeled  on  the  Berkeley  UNIX
          rogue  game.   Large  portions  of this document were shamelessly
          cribbed from A Guide to the Dungeons of Doom, by Michael  C.  Toy
          and  Kenneth  C.  R. C. Arnold.  Small portions were adapted from
          Further Exploration of the Dungeons of Doom, by Ken Arromdee.

               NetHack is the product of literally scores of people's work.
          Main  events  in the course of the game development are described
          below:

               Jay Fenlason wrote the original Hack, with help  from  Kenny
          Woodland, Mike Thome, and Jon Payne.

               Andries  Brouwer  did  a  major  re-write while at Stichting
          Mathematisch Centrum (now Centrum Wiskunde & Informatica), trans-
          forming  Hack  into a very different game.  He published the Hack
          source code for use on UNIX systems by  posting  that  to  Usenet
          newsgroup net.sources (later renamed comp.sources) releasing ver-
          sion 1.0 in December of 1984, then versions 1.0.1, 1.0.2, and fi-
          nally  1.0.3  in  July  of 1985.  Usenet newsgroup net.games.hack
          (later   renamed   rec.games.hack,   eventually    replaced    by
          rec.games.roguelike.nethack) was created for discussing it.

               Don  G. Kneller ported Hack 1.0.3 to Microsoft C and MS-DOS,
          producing PC HACK 1.01e, added support for DEC  Rainbow  graphics
          in  version 1.03g, and went on to produce at least four more ver-
          sions (3.0, 3.2, 3.51, and 3.6; note that these are old Hack ver-
          sion numbers, not contemporary NetHack ones).

               R.  Black  ported  PC  HACK  3.51 to Lattice C and the Atari
          520/1040ST, producing ST Hack 1.03.

               Mike Stephenson merged these various versions back together,
          incorporating  many  of  the added features, and produced NetHack
          version 1.4 in 1987.  He then coordinated a cast of thousands  in
          enhancing and debugging NetHack 1.4 and released NetHack versions
          2.2 and 2.3.  Like Hack, they  were  released  by  posting  their
          source  code  to  Usenet where they remained available in various
          archives accessible via ftp and  uucp  after  expiring  from  the
          newsgroup.

               Later,  Mike coordinated a major re-write of the game, head-
          ing a team which included Ken Arromdee,  Jean-Christophe  Collet,
          Steve  Creps,  Eric  Hendrickson, Izchak Miller, Eric S. Raymond,
          John Rupley, Mike Threepoint, and Janet Walz, to produce  NetHack
          3.0c.

               NetHack  3.0  was  ported  to the Atari by Eric R. Smith, to
          OS/2 by Timo Hakulinen, and to VMS by David Gentzel.   The  three
          of them and Kevin Darcy later joined the main NetHack Development
          Team to produce subsequent revisions of 3.0.

               Olaf Seibert ported NetHack 2.3 and 3.0 to the Amiga.   Norm
          Meluch,  Stephen  Spackman  and Pierre Martineau designed overlay
          code for PC NetHack 3.0.  Johnny Lee ported NetHack  3.0  to  the
          Macintosh.   Along with various other Dungeoneers, they continued
          to enhance the PC, Macintosh, and Amiga ports through  the  later
          revisions of 3.0.

               Version  3.0  went  through  ten relatively rapidly released
          "patch-level" revisions.  Versions at the time were known as  3.0
          for  the  base  release  and  variously as "3.0a" through "3.0j",
          "3.0 patchlevel 1"  through  "3.0 patchlevel 10",   or   "3.0pl1"
          through "3.0pl10" rather than 3.0.0 and 3.0.1 through 3.0.10; the
          three component numbering scheme began to be used with 3.1.0.

               Headed by Mike Stephenson and coordinated by  Izchak  Miller
          and  Janet  Walz, the NetHack Development Team which now included
          Ken Arromdee, David Cohrs, Jean-Christophe Collet,  Kevin  Darcy,
          Matt  Day, Timo Hakulinen, Steve Linhart, Dean Luick, Pat Rankin,
          Eric Raymond, and Eric Smith undertook a radical revision of 3.0.
          They re-structured the game's design, and re-wrote major parts of
          the code.  They added multiple dungeons, a new  display,  special
          individual  character  quests,  a  new endgame and many other new
          features, and produced NetHack 3.1.  Version 3.1.0  was  released
          in January of 1993.

               Ken  Lorber,  Gregg  Wonderly and Greg Olson, with help from
          Richard Addison, Mike Passaretti,  and  Olaf  Seibert,  developed
          NetHack 3.1 for the Amiga.

               Norm  Meluch and Kevin Smolkowski, with help from Carl Sche-
          lin, Stephen Spackman, Steve VanDevender, and Paul Winner, ported
          NetHack 3.1 to the PC.

               Jon W{tte and Hao-yang Wang, with help from Ross Brown, Mike
          Engber, David Hairston, Michael Hamel, Jonathan  Handler,  Johnny
          Lee,  Tim  Lennan, Rob Menke, and Andy Swanson, developed NetHack
          3.1 for the Macintosh, porting it for MPW.  Building on their de-
          velopment, Bart House added a Think C port.

               Timo Hakulinen ported NetHack 3.1 to OS/2.  Eric Smith port-
          ed NetHack 3.1 to the Atari.  Pat Rankin, with help  from  Joshua
          Delahunty,  was  responsible  for the VMS version of NetHack 3.1.
          Michael Allison ported NetHack 3.1 to Windows NT.

               Dean Luick, with help from David  Cohrs,  developed  NetHack
          3.1 for X11.  It drew the map as text rather than graphically but
          included nh10.bdf, an optionally used custom X11 font  which  has
          tiny  images  in place of letters and punctuation, a precursor of
          tiles.  Those images don't extend to individual monster  and  ob-
          ject  types, just replacements for monster and object classes (so
          one custom image for all "a" insects and another for all "["  ar-
          mor and so forth, not separate images for beetles and ants or for
          cloaks and boots).

               Warwick Allison wrote a  graphically  displayed  version  of
          NetHack  for  the Atari where the tiny pictures were described as
          "icons" and were distinct for specific types of monsters and  ob-
          jects rather than just their classes.  He contributed them to the
          NetHack Development Team which rechristened them "tiles",  origi-
          nal  usage which has subsequently been picked up by various other
          games.  NetHack's tiles support was  then  implemented  on  other
          platforms  (initially  MS-DOS but eventually Windows, Qt, and X11
          too).

               The 3.2 NetHack Development Team, comprised of Michael Alli-
          son, Ken Arromdee, David Cohrs, Jessie Collet, Steve Creps, Kevin
          Darcy, Timo Hakulinen, Steve Linhart, Dean Luick, Pat Rankin, Er-
          ic  Smith, Mike Stephenson, Janet Walz, and Paul Winner, released
          version 3.2.0 in April of 1996.

               Version 3.2 marked the tenth anniversary of the formation of
          the  development team.  In a testament to their dedication to the
          game, all thirteen members of the  original  NetHack  Development
          Team  remained  on the team at the start of work on that release.
          During the interval between the release of 3.1.3 and  3.2.0,  one
          of  the  founding  members  of  the NetHack Development Team, Dr.
          Izchak Miller, was diagnosed with cancer and passed  away.   That
          release  of  the game was dedicated to him by the development and
          porting teams.

               Version 3.2 proved to be more stable than previous versions.
          Many  bugs were fixed, abuses eliminated, and game features tuned
          for better game play.

               During the lifespan of NetHack 3.1 and 3.2, several enthusi-
          asts  of  the  game added their own modifications to the game and
          made these "variants" publicly available:

               Tom Proudfoot and Yuval Oren created  NetHack++,  which  was
          quickly  renamed  NetHack--  when some people incorrectly assumed
          that it was a conversion of the C source code  to  C++.   Working
          independently,  Stephen  White wrote NetHack Plus.  Tom Proudfoot
          later merged NetHack Plus and his own NetHack-- to produce SLASH.
          Larry  Stewart-Zerba and Warwick Allison improved the spell cast-
          ing system with the Wizard Patch.  Warwick  Allison  also  ported
          NetHack to use the Qt interface.

               Warren  Cheung  combined SLASH with the Wizard Patch to pro-
          duce Slash'EM, and with the help of Kevin Hugo, added  more  fea-
          tures.   Kevin  later joined the NetHack Development Team and in-
          corporated the best of these ideas into NetHack 3.3.

               The final update to 3.2 was the bug fix release 3.2.3, which
          was  released  simultaneously with 3.3.0 in December 1999 just in
          time for the Year 2000.  Because of the newer version, 3.2.3  was
          released  as  a source code patch only, without any ready-to-play
          distribution for systems that usually had such.

               (To anyone considering resurrecting  an  old  version:   all
          versions  before  3.2.3  had a Y2K bug.  The high scores file and
          the log file contained dates which were formatted  using  a  two-
          digit  year,  and 1999's year 99 was followed by 2000's year 100.
          That got written out successfully but it  unintentionally  intro-
          duced  an  extra  column in the file layout which prevented score
          entries from being read back in correctly, interfering  with  in-
          sertion  of  new  high scores and with retrieval of old character
          names to use for random ghost and statue  names  in  the  current
          game.)

               The  3.3 NetHack Development Team, consisting of Michael Al-
          lison, Ken Arromdee, David Cohrs,  Jessie  Collet,  Steve  Creps,
          Kevin  Darcy, Timo Hakulinen, Kevin Hugo, Steve Linhart, Ken Lor-
          ber, Dean Luick, Pat Rankin, Eric Smith, Mike  Stephenson,  Janet
          Walz,  and Paul Winner, released 3.3.0 in December 1999 and 3.3.1
          in August of 2000.

               Version 3.3 offered many firsts. It was the first version to
          separate  race and profession. The Elf class was removed in pref-
          erence to an elf race, and the races of dwarves, gnomes, and orcs
          made  their  first  appearance in the game alongside the familiar
          human race.  Monk and Ranger roles joined Archeologists,  Barbar-
          ians,   Cavemen,  Healers,  Knights,  Priests,  Rogues,  Samurai,
          Tourists, Valkyries and of course,  Wizards.   It  was  also  the
          first  version  to  allow  you to ride a steed, and was the first
          version to have a publicly available  web-site  listing  all  the
          bugs  that  had been discovered.  Despite that constantly growing
          bug list, 3.3 proved stable enough to last for more than  a  year
          and a half.

               The  3.4  NetHack  Development  Team  initially consisted of
          Michael Allison, Ken Arromdee, David Cohrs, Jessie Collet,  Kevin
          Hugo,  Ken Lorber, Dean Luick, Pat Rankin, Mike Stephenson, Janet
          Walz, and Paul Winner, with  Warwick Allison joining just  before
          the release of NetHack 3.4.0 in March 2002.

               As  with version 3.3, various people contributed to the game
          as a whole as well as supporting ports on the different platforms
          that NetHack runs on:

               Pat Rankin maintained 3.4 for VMS.

               Michael  Allison maintained NetHack 3.4 for the MS-DOS plat-
          form.  Paul Winner and Yitzhak Sapir provided encouragement.

               Dean Luick, Mark Modrall, and Kevin Hugo maintained and  en-
          hanced the Macintosh port of 3.4.

               Michael  Allison,  David  Cohrs, Alex Kompel, Dion Nicolaas,
          and Yitzhak Sapir maintained and enhanced 3.4 for  the  Microsoft
          Windows platform.  Alex Kompel contributed a new graphical inter-
          face for the Windows port.  Alex Kompel also contributed  a  Win-
          dows CE port for 3.4.1.

               Ron Van Iwaarden was the sole maintainer of NetHack for OS/2
          the past several releases. Unfortunately Ron's last OS/2  machine
          stopped  working  in  early  2006. A great many thanks to Ron for
          keeping NetHack alive on OS/2 all these years.

               Janne Salmijarvi and Teemu Suikki  maintained  and  enhanced
          the  Amiga  port of 3.4 after Janne Salmijarvi resurrected it for
          3.3.1.

               Christian "Marvin" Bressler maintained 3.4 for the Atari af-
          ter he resurrected it for 3.3.1.

               The release of NetHack 3.4.3 in December 2003 marked the be-
          ginning of a long release hiatus. 3.4.3 proved to be a remarkably
          stable version that provided continued enjoyment by the community
          for more than a decade. The NetHack Development Team  slowly  and
          quietly  continued  to  work on the game behind the scenes during
          the tenure of 3.4.3. It was during that same period that  several
          new  variants  emerged  within  the  NetHack  community.  Notably
          sporkhack by Derek S. Ray, unnethack by Patric Mueller, nitrohack
          and  its  successors originally by Daniel Thaler and then by Alex
          Smith, and Dynahack by Tung Nguyen.  Some of those variants  con-
          tinue  to  be developed, maintained, and enjoyed by the community
          to this day.

               In September 2014, an interim snapshot of the code under de-
          velopment  was  released  publicly  by other parties.  Since that
          code was a work-in-progress and had not gone through the  process
          of  debugging  it  as a suitable release, it was decided that the
          version numbers present on that code snapshot  would  be  retired
          and  never  used in an official NetHack release.  An announcement
          was posted on the NetHack Development Team's official nethack.org
          website  to  that  effect,  stating  that  there would never be a
          3.4.4, 3.5, or 3.5.0 official release version.

               In January  2015,  preparation  began  for  the  release  of
          NetHack 3.6.

               At  the  beginning  of development for what would eventually
          get released as 3.6.0, the NetHack Development Team consisted  of
          Warwick  Allison,  Michael  Allison,  Ken  Arromdee, David Cohrs,
          Jessie Collet, Ken Lorber, Dean Luick, Pat Rankin, Mike  Stephen-
          son,  Janet  Walz,  and Paul Winner.  In early 2015, ahead of the
          release of 3.6.0, new members Sean Hunt, Pasi Kallinen, and Derek
          S. Ray joined the NetHack Development Team.

               Near the end of the development of 3.6.0, one of the signif-
          icant inspirations for many of  the  humorous  and  fun  features
          found  in the game, author Terry Pratchett, passed away.  NetHack
          3.6.0 introduced a tribute to him.

               3.6.0 was released in December 2015, and merged work done by
          the  development team since the release of 3.4.3 with some of the
          beloved community patches. Many bugs were fixed and some code was

          restructured.

               The  NetHack  Development Team, as well as Steve VanDevender
          and Kevin Smolkowski, ensured that NetHack 3.6 continued to oper-
          ate on various UNIX flavors and maintained the X11 interface.

               Ken  Lorber,  Haoyang Wang, Pat Rankin, and Dean Luick main-
          tained the port of NetHack 3.6 for Mac OSX.

               Michael Allison, David Cohrs,  Bart  House,  Pasi  Kallinen,
          Alex  Kompel, Dion Nicolaas, Derek S. Ray and Yitzhak Sapir main-
          tained the port of NetHack 3.6 for Microsoft Windows.

               Pat Rankin attempted  to  keep  the  VMS  port  running  for
          NetHack 3.6, hindered by limited access. Kevin Smolkowski has up-
          dated and tested it for the most recent version of OpenVMS  (V8.4
          as of this writing) on Alpha and Integrity (aka Itanium aka IA64)
          but not VAX.

               Ray Chason resurrected the MS-DOS port for 3.6 and  contrib-
          uted the necessary updates to the community at large.

               In  late April 2018, several hundred bug fixes for 3.6.0 and
          some new features were assembled and released as  NetHack  3.6.1.
          The NetHack Development Team at the time of release of 3.6.1 con-
          sisted of Warwick Allison, Michael Allison, Ken  Arromdee,  David
          Cohrs,  Jessie  Collet,  Pasi  Kallinen,  Ken Lorber, Dean Luick,
          Patric Mueller, Pat  Rankin,  Derek  S.  Ray,  Alex  Smith,  Mike
          Stephenson, Janet Walz, and Paul Winner.

               In early May 2019, another 320 bug fixes along with some en-
          hancements and the adopted curses window port, were  released  as
          3.6.2.

               Bart  House,  who  had  contributed to the game as a porting
          team participant for decades, joined the NetHack Development Team
          in late May 2019.

               NetHack  3.6.3  was  released on December 5, 2019 containing
          over 190 bug fixes to NetHack 3.6.2.

               NetHack 3.6.4 was released on December 18, 2019 containing a
          security fix and a few bug fixes.

               NetHack  3.6.5  was  released on January 27, 2020 containing
          some security fixes and a small number of bug fixes.

               NetHack 3.6.6 was released on March 8, 2020 containing a se-
          curity fix and some bug fixes.

               On behalf of the NetHack community, thank you very much once
          again  to M. Drew Streib and Pasi Kallinen for providing a public
          NetHack server at nethack.alt.org. Thanks to  Keith  Simpson  and

          geoneers who invest their time and  effort  into  annual  NetHack
          tournaments  such  as Junethack, The November NetHack Tournament,
          and in days past, devnull.net (gone for now, but not  forgotten).



          12.2.  Dungeoneers

               From  time  to  time,  some depraved individual out there in
          netland sends a particularly intriguing modification to help  out
          with the game.  The NetHack Development Team sometimes makes note
