nethack/doc/Guidebook.txt
PatR bb62ab6fc1 another Guidebook update - mostly NETHACKOPTIONS 
Move some 'roff macros from Guidebook.mn to new file tmac.nh.

Header for tmac.nh is not being updated, even after explicitly adding
it to .gitattributes.  I'm not sure what I've done wrong.  (I'm using
'git nhadd doc/' here rather than explicit 'git nhadd doc/tmac.nh'.)

In Guidebook.mn, change the ``setenv NETHACKOPTIONS'' example so that
it fits within one line in Guidebook.txt.  (I looked at 3.4.3's
edition of that file and the example went not just beyond the margin
of the formatted text but beyond 80 columns, so wrapped in an ugly
fashion.)  I had previously changed 'autoquiver' to 'color' to shorten
it, now have changed '!autopickup' to '!leg' to show an example of
truncated option name as well as shorten, and also 'fruit:papaya' to
'fruit:lime' to squeeze out the last two columns needed to fit within
the text margin while retaining 'name:Blue Meanie' as requested.
Guidebook.txt shows both NETHACKOPTIONS examples with indentation
suppressed, Guidebook.ps uses normal indentation (evidently using a
narrower font, even with \f(CR (constant-width Roman) to approximate
TeX's \tt, since the indented example fits fine and looks better).

Some Guidebook.tex catchup.  I suspect that lots of bits and bobs
don't match between Guidebook.mn and Guidebook.tex these days.
Particularly quoting and variant font (italics, bold, \tt) usage.
Also the recently added box around the sample screenshot.  This
modifies the screenshot to match Guidebook.mn's, reflecting change
in status field spacing by STATUS_HILITES.

Raw Blame History

A Guide to the Mazes of Menace
(Guidebook for NetHack)
Original version - Eric S. Raymond
(Edited and expanded for 3.6 by Mike Stephenson and others)
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.
NetHack Guidebook 1
NetHack Guidebook 2
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 3.6 October 16, 2018
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 3.6 October 16, 2018
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 assis-
tance 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 lines of the screen contain several cryptic
pieces of information describing your current status. If either
status line becomes longer than the width of the screen, you
might not see all of it. Here are explanations of what the vari-
ous status items mean (though your configuration may not have all
the status items listed below):
Rank
Your character's name and professional ranking (based on the
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.
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
NetHack 3.6 October 16, 2018
NetHack Guidebook 6
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.
Experience
Your current experience level and experience points. As you
adventure, you gain experience points. At certain experi-
ence point totals, you gain an experience level. The more
experienced you are, the better you fight and withstand mag-
ical attacks. Many dungeons show only your experience level
NetHack 3.6 October 16, 2018
NetHack Guidebook 7
here.
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 `^X'
command shows all relevant status conditions.
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 (|).
NetHack 3.6 October 16, 2018
NetHack Guidebook 8
. 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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 9
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 inven-
tory letters of every object you're carrying. Finally, if you
change your mind and decide you don't want to do this command af-
ter 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
NetHack 3.6 October 16, 2018
NetHack Guidebook 10
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 down to the next level (if you are on a staircase or lad-
der).
[yuhjklbn]
Go one step in the direction indicated (see Figure 2). 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."
y k u 7 8 9
\ | / \ | /
h- . -l 4- . -6
/ | \ / | \
b j n 1 2 3
(if number_pad is set)
Figure 2
[YUHJKLBN]
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).
NetHack 3.6 October 16, 2018
NetHack Guidebook 11
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).
A few other commands (eat food, offer sacrifice, apply tin-
ning-kit) 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. The prefix will make "#trav-
el" command show a menu of interesting targets in sight.
F[yuhjklbn]
Prefix: fight a monster (even if you only guess one is
there).
M[yuhjklbn]
Prefix: move far, no pickup.
g[yuhjklbn]
Prefix: move until something interesting is found.
G[yuhjklbn] or <CONTROL->[yuhjklbn]
Prefix: same as `g', but forking of corridors is not con-
sidered interesting.
_ 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' command, but without picking
up objects, similar to the `M' command. For ports with
mouse support, the command is also invoked when a mouse-
click takes place on a location other than the current posi-
tion.
. Wait or rest, do nothing for one turn.
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 Redo the previous command.
NetHack 3.6 October 16, 2018
NetHack Guidebook 12
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.
Ex. "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? [!%= BUCXaium]"
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.
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 three 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), and bless/curse state (`B', `U',
`C', and `X' as shown above). If you specify more than one
value in a category (such as "!?" for potions and scrolls or
"BU" for blessed and uncursed), 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 select all potions and scrolls which are known
to be blessed or uncursed. (In versions prior to 3.6, fil-
ter combinations behaved differently.)
^D Kick something (usually a door).
e Eat food.
NetHack 3.6 October 16, 2018
NetHack Guidebook 13
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.
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.
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;
I$ - count your money.
o Open a door.
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.
^O Show overview.
Shortcut for "#overview": list interesting dungeon levels
visited.
NetHack 3.6 October 16, 2018
NetHack Guidebook 14
(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. The behavior can
be varied via the msg_window option.
q Quaff (drink) something (potion, water, etc).
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.
(In versions prior to 3.3 this was the command to quit the
game, which has been moved to "#quit".)
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.
Can also be used to figure out whether there is still a mon-
ster at an adjacent "remembered, unseen monster" marker.
NetHack 3.6 October 16, 2018
NetHack Guidebook 15
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.
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.)
^T Teleport, if you have the ability.
v Display version number.
V Display the game history.
w Wield weapon.
w- - wield nothing, use your bare (or gloved) hands.
Some characters can wield two weapons at once; use the `X'
NetHack 3.6 October 16, 2018
NetHack Guidebook 16
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.
X Toggle two-weapon combat, if your character can do it. Also
available via the "#twoweapon" extended command.
(In versions prior to 3.6 this was the command to switch
from normal play to "explore mode", also known as "discovery
mode", which has now been moved to "#exploremode".)
^X Display basic information about your character.
Displays name, role, race, gender (unless role name makes
that redundant, such as Caveman or Priestess), and align-
ment, along with your patron deity and his or her opposi-
tion. It also shows most of the various items of informa-
tion from the status line(s) in a less terse form, including
several additional things which don't appear in the normal
status display due to space considerations.
In normal play, that's all that `^X' displays. In explore
mode, the role and status feedback is augmented by the in-
formation provided by enlightenment magic.
z Zap a wand.
z. - to aim at yourself, use `.' for the direction.
Z Zap (cast) a spell.
Z. - to cast at yourself, use `.' for the direction.
^Z Suspend the game (UNIX(R) versions with job control only).

Combines the preceding five type-specific commands into one.
$ Count your gold pieces.
+ 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
current `+' command finishes. Sorting the whole list is
temporary. To make the most recent sort order persist be-
yond the current `+' command, choose the sort option again
and then pick "reassign casting letters". (Any spells
learned after that will be added to the end of the list
rather than be inserted into the sorted ordering.)
\ Show what types of objects have been discovered.
` Show discovered types for one class of objects.
! Escape to a shell.
# Perform an extended command.
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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 18
#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
key is `M-A', and also `^N' if number_pad is on.
#apply
Apply (use) a tool such as a pick-axe, a key, or a lamp.
Default key is `a'.
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.
#attributes
Show your attributes. Default key is `^X'.
#autopickup
Toggle the autopickup option on/off. Default key is `@'.
#call
Call (name) a monster, or an object in inventory, on the

#monster
Use a monster's special ability (when polymorphed into mon-
ster form). Autocompletes. Default key is `M-m'.

Same as "#call". Autocompletes. Default keys are `N', `M-
n', and `M-N'.
#offer
Offer a sacrifice to the gods. Autocompletes. Default key

You'll need to find an altar to have any chance at success.
Corpses of recently killed monsters are the fodder of
choice.

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-
ited level will be included regardless of annotations. Au-
tocompletes. Default keys are `^O', and `M-O'.
#panic
Test the panic routine. Terminates the current game. Auto-
completes. Debug mode only.

#pray
Pray to the gods for help. Autocompletes. Default key is
`M-p'.
NetHack 3.6 October 16, 2018
NetHack Guidebook 22
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.
#prevmsg
Show previously displayed game messages. Default key is
`^P'.
#puton
Put on an accessory (ring, amulet, etc). Default key is
`P'.
#quaff
Quaff (drink) something. Default key is `q'.
#quit
Quit the program without saving your game. Autocompletes.
Default key is `M-q'.
Since using this command by accident would throw away the
current game, you are asked to confirm your intent before
quitting. By default a response of `y' acknowledges that
intent. You can set the paranoid_confirmation option to re-
quire 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
is `r'.

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.

Help menu: get the list of available extended commands.
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.
In NT, OS/2, PC and ST NetHack, the "Alt" key can be used in
this fashion; on the Amiga, set the altmeta option to get this
behavior. 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.

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. You can find them with the `s'
(search) command.
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.
You can get through a locked door by using a tool to pick
the lock with the `a' (apply) command, or by kicking it open with
the `^D' (kick) command.
Open doors cannot be entered diagonally; you must approach
them straight on, horizontally or vertically. Doorways without
doors are not restricted in this fashion.
Doors can be useful for shutting out monsters. Most mon-
sters cannot open doors, although a few don't need to (ex. ghosts
can walk through doors).
Secret doors are hidden. You can find them with the `s'
(search) command. Once found they are in all ways equivalent to
normal doors.
5.2. Traps (`^')
There are traps throughout the dungeon to snare the unwary
delver. For example, you may suddenly fall into a pit and be
stuck for a few turns trying to climb out. Traps don't appear on
your map until you see one triggered by moving onto it, see some-
thing fall into it, or you discover it with the `s' (search) com-
mand. Monsters can fall prey to traps, too, which can be a very
useful defensive strategy.
There is a special pre-mapped branch of the dungeon based on
the classic computer game "Sokoban." The goal is to push the
NetHack 3.6 October 16, 2018
NetHack Guidebook 29
boulders into the pits or holes. With careful foresight, it is
possible to complete all of the levels according to the tradi-
tional rules of Sokoban. Some allowances are permitted in case
the player gets stuck; however, they will lower your luck.
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.
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
NetHack 3.6 October 16, 2018
NetHack Guidebook 30
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 sometimes 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 (in inventory, not inside bags or boxes), will also show
current shop debt or credit, if any. The "Iu" command lists un-
paid items (those which still belong to the shop) if you are car-
rying any. The "Ix" command shows an inventory-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 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.
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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 31
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.
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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 32
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.
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
more.
7. Objects
When you find something in the dungeon, it is common to want
to pick it up. In NetHack, this is accomplished automatically by
NetHack 3.6 October 16, 2018
NetHack Guidebook 33
walking over the object (unless you turn off the autopickup op-
tion (see below), or move with the `m' prefix (see above)), or
manually by using the `,' command.
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
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
NetHack 3.6 October 16, 2018
NetHack Guidebook 34
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. Blessed items usually work
better or more beneficially than normal uncursed items. For ex-
ample, a blessed weapon will do 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.
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 "un-
cursed" be displayed even when that can be deduced from other at-
tributes.
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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 35
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
in an appendix to Unearthed Arcana, an AD&D supplement.
The commands to use weapons are `w' (wield), `t' (throw),
`f' (fire, an alternate way of throwing), `Q' (quiver), `x' (ex-
change), `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.
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 3.6 October 16, 2018
NetHack Guidebook 36
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.
Some characters have the ability to fire a volley of multi-
ple items in a single turn. 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 arrows, in crossbow skill if you're
wielding one to shoot bolts, or in sling skill if you're wielding
one to shoot stones). The number 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 example, "2f" (or "n2f" if using num-
ber_pad mode) would ensure that at most 2 arrows are shot even if
you could have fired 3. If you 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 speci-
fied. Once the volley is in motion, all of the items will travel
in the same direction; if the first ones kill a monster, the oth-
ers 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
NetHack 3.6 October 16, 2018
NetHack Guidebook 37
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" com-
mand. 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 sec-
ondary is just an item in your inventory that's been designated
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
NetHack 3.6 October 16, 2018
NetHack Guidebook 38
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 an (incomplete) list of the armor
classes provided by various suits of armor:
dragon scale mail 1
plate mail 3
crystal plate mail 3
bronze plate mail 4
splint mail 4
banded mail 4
dwarvish mithril-coat 4
elven mithril-coat 5
chain mail 5
orcish chain mail 6
scale mail 6
dragon scales 7
studded leather armor 7
ring mail 7
orcish ring mail 8
leather armor 8
leather jacket 9
no armor 10
You can also wear other pieces of armor (ex. helmets, boots,
shields, cloaks) to lower your armor class even further, but you
can only wear one item of each category (one suit of armor, one
cloak, one helmet, one shield, and so on) at a time.
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 commands to use armor are `W' (wear) and `T' (take off).
The `A' command can also be used to take off armor as well as
other worn items.
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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 39
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-ef-
fects.
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 (ex. "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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 40
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
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 only
two rings, one on each ring finger.
Most rings also cause you to grow hungry more rapidly, the
rate varying with the type of ring.
The commands to use rings are `P' (put on) and `R' (remove).
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
NetHack 3.6 October 16, 2018
NetHack Guidebook 41
mystic 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.
The command to use tools is `a' (apply).
NetHack 3.6 October 16, 2018
NetHack Guidebook 42
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.
The commands to use amulets are the same as for rings, `P'
(put on) and `R' (remove).
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
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.
Very large humanoids (giants and their ilk) have been known
to use boulders as weapons.
For some configurations of the program, statues are no
longer shown as ``' but by the letter representing the monster
they depict instead.
NetHack 3.6 October 16, 2018
NetHack Guidebook 43
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).
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, if 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
exception is that if the object gets covered by the "remembered,
unseen monster" marker. When that marker is later removed after
you've verified that no monster is there, you will forget that
there was any object there regardless of whether the unseen mon-
ster 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
NetHack 3.6 October 16, 2018
NetHack Guidebook 44
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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 45
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 cannot read or write. This includes
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 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.
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 MS-DOS and Windows, it is
"defaults.nh" in the same folder as nethack.exe or nethackW.exe.
On UNIX, Linux, and Mac OS X it is ".nethackrc" in the user's
NetHack 3.6 October 16, 2018
NetHack Guidebook 46
home directory. The file may not exist, but it is a normal ASCII
text file and can be created with any text editor.
Any line in the configuration file starting with `#' is
treated as a comment. Empty lines are ignored.
Any line beginning with `[' and ending in `]' is considered
a section marker. The text between the square brackets is the
section name. Lines after a section marker belong to that sec-
tion, and are ignored unless a CHOOSE statement was used to se-
lect that section. Section names are case insensitive.
You can use different configuration statements in the file,
some of which can be used multiple times. In general, the state-
ments are written in capital letters, followed by an equals sign,
followed by settings particular to that statement. Here is a
list of allowed statements:
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 statements, and multiple options in a single OPTIONS
statement.
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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 47
TROUBLEDIR
The location that a record of game aborts and self-diagnosed
game problems is kept. Defaults to HACKDIR, must be writable.
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, or extended commands. You can specify multiple bindings.
Format is key followed by the command, separated 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
MSGTYPE
Change the way messages are shown in the top status line. See
the "Configuring Message Types" section.
MENUCOLOR
Highlight menu lines with different colors. See the "Configur-
ing Menu Colors" section.
SYMBOLS
Override one or more symbols in the symbols files. See the
"Modifying NetHack Symbols" section.
NetHack 3.6 October 16, 2018
NetHack Guidebook 48
Example:
SYMBOLS=S_boulder:0
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
SOUNDDIR
Define the directory that contains the sound files. See the
"Configuring User Sounds" section.
SOUND
Define a sound mapping. See the "Configuring User Sounds" sec-
tion.
Here is a short example of config 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
OPTIONS=autopickup,pickup_types:$"=/!?+
# Show colored text if possible
OPTIONS=color
# Show lit corridors differently
OPTIONS=lit_corridor
#
# No startup splash screen. Windows GUI only.
OPTIONS=!splash_screen
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"
NetHack 3.6 October 16, 2018
NetHack Guidebook 49
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.
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.
align
Your starting alignment (align:lawful, align:neutral, or
align:chaotic). You may specify just the first letter. The
default is to randomly pick an appropriate alignment. If you
prefix the value with `!' or "no", you will exclude that align-
ment from being picked randomly. Cannot be set with the `O'
command. Persistent.
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 door attempts to open it (default true). Persis-
tent.
autopickup
Automatically pick up things onto which you move (default on).
Persistent. See pickup_types to refine the behavior.
NetHack 3.6 October 16, 2018
NetHack Guidebook 50
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.
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 (ex. "catname:Morris"). Cannot be set
with the `O' command.
character
Synonym for "role" to pick the type of your character (ex.
"character:Monk"). See role for more details.
checkpoint
Save game state after each level change, for possible recovery
after program crash (default on). Persistent.
checkspace
Check free disk space before writing files to disk (default
on). You may have to turn this off if you have more than 2 GB
free space on the partition used for your save and level files
(because too much space might overflow the calculation and end
up looking like insufficient space). Only applies when MFLOPPY
was defined during compilation.
clicklook
Allows looking at things on the screen by navigating the mouse
over them and clicking the right mouse button (default off).
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
NetHack 3.6 October 16, 2018
NetHack Guidebook 51
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;
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.
(ex. "disclose:yi na +v -g o") The example sets inventory to
prompt and default to yes, attributes to prompt and default to
no, vanquished to disclose without prompting, genocided to not
disclose and not prompt, conduct to implicitly prompt and de-
fault 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 dun-
geon overview shows all levels you had visited but does not re-
veal things about them that you hadn't discovered.
NetHack 3.6 October 16, 2018
NetHack Guidebook 52
dogname
Name your starting dog (ex. "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 only by the tty port (default off),
when the game has been compiled to support tty graphics.
female
An obsolete synonym for "gender:female". Cannot be set with
the `O' command.
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 (ex. "fruit:man-
go") (default "slime mold"). Basically a nostalgic whimsy that
NetHack uses from time to time. You should set this to some-
thing you find more appetizing than slime mold. Apples, or-
anges, 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 the "male" and "female" options, the "gender"
option will take precedence. The default is to randomly pick
an appropriate gender. If you prefix the value with `!' or
"no", you will exclude that gender from being picked randomly.
Cannot be set with the `O' command. Persistent.
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
NetHack 3.6 October 16, 2018
NetHack Guidebook 53
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.
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
Show a hit point bar graph behind your name and title. Only
available for TTY and Windows GUI, and only when statushilites
is on.
horsename
Name your starting horse (ex. "horsename:Trigger"). Cannot be
set with the `O' command.
ignintr
Ignore interrupt signals, including breaks (default off). Per-
sistent.
implicit_uncursed
Omit "uncursed" from inventory lists, if possible (default on).
legacy
Display an introductory message when starting the game (default
on). Persistent.
lit_corridor
Show corridor squares seen by night vision or a light source
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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 54
male
An obsolete synonym for "gender:male". Cannot be set with the
`O' command.
mention_walls
Give feedback when walking against a wall (default off).
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. Tradi-
tional was the only interface available for 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 ob-
jects 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 ob-
ject class filtering and immediately displays a menu of all ob-
jects. Persistent.
menu_deselect_all
Menu character accelerator to deselect all items in a menu.
Implemented by the Amiga, Gem, X11 and tty ports. Default `-'.
menu_deselect_page
Menu character accelerator to deselect all items on this page
of a menu. Implemented by the Amiga, Gem and tty ports. De-
fault `\'.
menu_first_page
Menu character accelerator to jump to the first page in a menu.
Implemented by the Amiga, Gem and tty ports. Default `^'.
menu_headings
Controls how the headings in a menu are highlighted. Values
are "none", "bold", "dim", "underline", "blink", or "inverse".
Not all ports can actually display all types.
menu_invert_all
Menu character accelerator to invert all items in a menu. Im-
plemented by the Amiga, Gem, X11 and tty ports. Default `@'.
menu_invert_page
Menu character accelerator to invert all items on this page of
a menu. Implemented by the Amiga, Gem and tty ports. Default
`~'.
NetHack 3.6 October 16, 2018
NetHack Guidebook 55
menu_last_page
Menu character accelerator to jump to the last page in a menu.
Implemented by the Amiga, Gem and tty ports. Default `|'.
menu_next_page
Menu character accelerator to goto the next menu page. Imple-
mented by the Amiga, Gem and tty ports. 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
Menu character accelerator to goto the previous menu page. Im-
plemented by the Amiga, Gem and tty ports. Default `<'.
menu_search
Menu character accelerator to search for a menu item. Imple-
mented by the Amiga, Gem, X11 and tty ports. Default `:'.
menu_select_all
Menu character accelerator to select all items in a menu. Im-
plemented by the Amiga, Gem, X11 and tty ports. Default `.'.
menu_select_page
Menu character accelerator to select all items on this page of
a menu. Implemented by the Amiga, Gem and tty ports. Default
`,'.
monpolycontrol
Prompt for new form whenever any monster changes shape (default
off). Debug mode only.
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.
(It is currently implemented for tty only.) The possible val-
ues 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
NetHack 3.6 October 16, 2018
NetHack Guidebook 56
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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 57
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 attack-
ing a peaceful monster;
wand-break - require "yes" rather than `y' to confirm breaking
a wand;
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.
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.
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
NetHack 3.6 October 16, 2018
NetHack Guidebook 58
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. You can use autopickup_exception config-
uration file lines to further refine autopickup behavior. Per-
sistent.
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 re-
sults 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.
race
Selects your race (for example, "race:human"). Default is ran-
dom. If you prefix the value with `!' or "no", you will ex-
clude that race from being picked randomly. Cannot be set with
the `O' command. Persistent.
rest_on_space
Make the space bar a synonym for the `.' (#wait) command (de-
fault off). Persistent.
role
Pick your type of character (ex. "role:Samurai"); synonym for
"character". See "name" for an alternate method of specifying
your role. Normally only the first letter of the value is ex-
amined; `r' is an exception with "Rogue", "Ranger", and "ran-
dom" values. If you prefix the value with `!' or "no", you
will exclude that role from being picked randomly. Cannot be
set with the `O' command. Persistent.
roguesymset
This option may be used to select one of the named symbol sets
NetHack 3.6 October 16, 2018
NetHack Guidebook 59
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.
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
(ex. "scores:5 top scores/4 around my score/own scores"). On-
ly the first letter of each category (`t', `a', or `o') is nec-
essary. 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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 60
silent
Suppress terminal beeps (default on). Persistent.
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.
sortpack
Sort the pack contents by type when displaying inventory (de-
fault on). Persistent.
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 (ex. "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" interface
only; "X11" interface always uses a timer based delay. The
NetHack 3.6 October 16, 2018
NetHack Guidebook 61
default is on if configured into the program.) Persistent.
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
(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 (default on). Turning this option off
will prevent the game from attempting unintended moves if you
make inadvertent mouse clicks on the map window. 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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 62
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)
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.
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
config file, and if the window port is capable of adjusting 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 sup-
ported by the window port that you are currently using by check-
ing to see if it shows up in the Options list. Some options are
dynamic and can be specified during the game with the `O' com-
mand.
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 an ascii character map if it

NetHack Guidebook 63
color
If NetHack can, it should display color if it can for different
monsters, objects, and dungeon features.
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.

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).
tiled_map
If NetHack can, it should display a tiled map if it can.
tile_file
Specify the name of an alternative tile file to override the
default.

Specify the preferred height of each tile in a tile capable
port.
NetHack 3.6 October 16, 2018
NetHack Guidebook 65
tile_width
Specify the preferred width of each tile in a tile capable port
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.
vary_msgcount
If NetHack can, it should display this number of messages at a
time in the message window.
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.
altkeyhandler
Select an alternate keystroke handler dll to load (Win32 tty
NetHack only). The name of the handler is specified without
the .dll extension and without any path information. Cannot be
set with the `O' command.
altmeta
On Amiga, this option controls whether typing "Alt" plus anoth-
er key functions as a meta-shift for that key (default on).
altmeta
On other (non-Amiga) systems where this option is available, it
can be set to tell NetHack to convert a two character sequence
NetHack 3.6 October 16, 2018
NetHack Guidebook 66
beginning with ESC into a meta-shifted version of the second
character (default 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 second 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.
soundcard
(default on, PC NetHack only). Cannot be set with the `O' com-
mand.
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 state-
ments in the config file if needed. Cannot be set with the `O'
command.
video
Set the video mode used (PC NetHack only). Values are "autode-
tect", "default", or "vga". Setting "vga" (or "autodetect"
with vga hardware present) will cause the game to display
tiles. Cannot be set with the `O' command.
NetHack 3.6 October 16, 2018
NetHack Guidebook 67
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
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.
A "never pickup" rule takes precedence over an "always pickup"
rule if both match.
Exceptions can be set with the `O' command, but ones set that
way will not be preserved across saves and restores.
Here are some examples:
NetHack 3.6 October 16, 2018
NetHack Guidebook 68
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"), 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 config file. You cannot bind object sym-
bols into menu accelerators.
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.

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 config file entries to configure 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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 72
Here's an example of message types using NetHack's internal
pattern matching facility:
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, win32tty and win32gui support this.
In general, the config file entries to configure 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, lightgreen, yellow, lightblue, lightmagen-
ta, lightcyan, and white.
Allowed attributes are none, bold, dim, underline, blink, and
inverse. Note that the platform used may interpret the at-
tributes 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 3.6 October 16, 2018
NetHack Guidebook 73
worn)" on the same line will be shown in red color and under-
lined. You can have multiple MENUCOLOR entries in your config
file, and the last MENUCOLOR-line in your config file 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 config 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
3.6);
pattern - the pattern to match;
sound file - the sound file to play;
volume - the volume to be set while playing the sound file.
The pattern should be a POSIX extended regular expression.
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.
The format for defining status colors is:
OPTION=hilite_status: field-name/behavior/color&attributes
For example, the following line in your config 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
NetHack 3.6 October 16, 2018
NetHack Guidebook 74
For another example, the following line in your config file
will cause wisdom to be displayed red if it drops and green if it
rises.
OPTION=hilite_status: wisdom/down/red/up/green
You can adjust the display of the following status fields:
title strength dexterity
constitution intelligence wisdom
charisma alignment score
carrying-capacity gold power
power-max experience-level armor-class
HD time hunger
hitpoints hitpoints-max dungeon-level
experience condition
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" and "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 valid for "power" and "hit-
points" fields.
NetHack 3.6 October 16, 2018
NetHack Guidebook 75
* 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. If
the number is prefixed with `<=' or `>=', 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.
Allowed colors are black, red, green, brown, blue, magenta,
cyan, gray, orange, lightgreen, yellow, lightblue, lightmagen-
ta, lightcyan, and white.
Allowed attributes are bold, inverse, underline, blink, dim,
and normal. Note that the platform used may interpret the at-
tributes any way it wants.
The in-game options menu can help you determine the correct
syntax for a config 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
Set the name of the symbol set that you want to load for dis-
play on the rogue level.
NetHack 3.6 October 16, 2018
NetHack Guidebook 76
You can also override one or more symbols using the SYMBOLS
config file option. Symbols are specified as name:value pairs.
Note that NetHack escape-processes the value string in conven-
tional C fashion. This means that \ is a prefix to take the fol-
lowing 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 following character to
be treated as a control character.

There is one additional class of object, described as
"strange object", which will occasionally be the shape taken on
by mimics and shown as `]' for maps displayed as text characters.
Although the displayed character is the same as the default value
for "S_mimic_def", it is a different symbol and there is no cor-
responding "S_strange_object" symbol nor any way to assign an al-
ternate value for it.
9.15. 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 the MS-DOS versions
of NetHack 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 capabili-
ties of their screen-readers to be quite valuable. Be certain to
examine this Guidebook before playing so you have an idea what
the screen layout 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 charac-
ter 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 often useful in giving players a better
NetHack 3.6 October 16, 2018
NetHack Guidebook 80
sense of the overall location 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.
While it is not difficult for experienced users to edit the
defaults.nh file to accomplish this, novices may find this task
somewhat daunting. Included within the "symbols" file of all of-
ficial distributions of NetHack is a symset called NHAccess. Se-
lecting that symset in your configuration file will cause the
game to run in a manner accessible to the blind. After you have
gained some experience with the game and with editing files, you
may want to alter settings via SYMBOLS= in your configuration
file to better suit your preferences. The most crucial settings
to make the game accessible are:
symset:NHAccess
Load a symbol set appropriate for use by blind players.
roguesymset:NHAccess
Load a symbol set for the rogue level that is 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.
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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 81
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.
9.16. 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).
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.
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
NetHack 3.6 October 16, 2018
NetHack Guidebook 82
verify that the user who is restoring is the same one who
saved).
The following options affect the score file:
PERSMAX = Maximum number of entries for one person.
ENTRYMAX = Maximum number of entries in the score file.
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.
MAX_STATUENAME_RANK = Maximum number of score file entries to
use for random statue names (default is 10).
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. Al-
lows the following placeholders:
%% - literal `%'
%v - version (eg. "3.6.2-0")
%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
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
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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 83
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 paper 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 dozens 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.
NetHack 3.6 October 16, 2018
NetHack Guidebook 84
Andries Brouwer did a major re-write, transforming Hack into
a very different game, and published (at least) three versions
(1.0.1, 1.0.2, and 1.0.3) for UNIX machines to the Usenet.
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).
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
1.4. He then coordinated a cast of thousands in enhancing and
debugging NetHack 1.4 and released NetHack versions 2.2 and 2.3.
Later, Mike coordinated a major rewrite of the game, heading
a team which included Ken Arromdee, Jean-Christophe Collet, Steve
Creps, Eric Hendrickson, Izchak Miller, John Rupley, Mike Threep-
oint, 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 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.
Headed by Mike Stephenson and coordinated by Izchak Miller
and Janet Walz, the development team which now included Ken Ar-
romdee, 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.
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
NetHack 3.6 October 16, 2018
NetHack Guidebook 85
Lee, Tim Lennan, Rob Menke, and Andy Swanson, developed NetHack
3.1 for the Macintosh, porting it for MPW. Building on their de-
velopment, Barton 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. Warwick Allison wrote a tiled version of NetHack
for the Atari; he later contributed the tiles to the DevTeam and
tile support was then added to other platforms.
The 3.2 development team, comprised of Michael Allison, Ken
Arromdee, David Cohrs, Jessie Collet, Steve Creps, Kevin Darcy,
Timo Hakulinen, Steve Linhart, Dean Luick, Pat Rankin, Eric
Smith, Mike Stephenson, Janet Walz, and Paul Winner, released
version 3.2 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 development team re-
mained on the team at the start of work on that release. During
the interval between the release of 3.1.3 and 3.2, one of the
founding members of the 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.
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--. Working independently, Stephen White
wrote NetHack Plus. Tom Proudfoot later merged NetHack Plus and
his own NetHack-- to produce SLASH. Larry Stewart-Zerba and War-
wick Allison improved the spell casting system with the Wizard
Patch. Warwick Allison also ported NetHack to use the Qt inter-
face.
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 DevTeam and incorporated the best
of these ideas in 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.
The 3.3 development team, consisting of Michael Allison, Ken
Arromdee, David Cohrs, Jessie Collet, Steve Creps, Kevin Darcy,
Timo Hakulinen, Kevin Hugo, Steve Linhart, Ken Lorber, Dean
Luick, Pat Rankin, Eric Smith, Mike Stephenson, Janet Walz, and
NetHack 3.6 October 16, 2018
NetHack Guidebook 86
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 development team initially consisted of Michael Al-
lison, 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 re-
lease 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 devteam 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 origi-
nally by Daniel Thaler and then by Alex Smith, and Dynahack by
Tung Nguyen. Some of those variants continue 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 ver-
sion numbers present on that code snapshot would be retired and
never used in an official NetHack release. An announcement was
posted on the devteam's official nethack.org website to that ef-
fect, 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 development team consisted of Warwick
Allison, Michael Allison, Ken Arromdee, David Cohrs, Jessie Col-
let, Ken Lorber, Dean Luick, Pat Rankin, Mike Stephenson, 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.
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 development team at the time of release of 3.6.1 consisted 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.
The development team, as well as Steve VanDevender and Kevin
Smolkowski, ensured that NetHack 3.6 continued to operate on var-
ious 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, Barton 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 3.6.1, hindered by limited access. Kevin Smolkowski has
updated 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 msdos port for 3.6.1 and contrib-
uted the necessary updates to the community at large.

12.1. SPECIAL THANKS
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
Andy Thomson for hardfought.org. Thanks to all those unnamed dun-
geoneers who invest their time and effort into annual NetHack
tournaments such as Junethack and in days past, devnull.net (gone
for now, but not forgotten).
