Pasi Kallinen 2288452278 Monsters can see player resistances 
If monsters see you resist something, generally elemental or magical
attack, or if they see you reflect an attack, they learn that and
will adjust their attack accordingly.

Originally from SporkHack, but this version comes via EvilHack with
some minor changes.

/* The weapon_check flag is used two ways:

* 2) Between calls to mon_wield_item, is 0 or 1 depending on whether or not
* the weapon is known by the monster to be cursed (so it shouldn't bother
* trying for another weapon).
* I originally planned to also use 0 if the monster already had its best
* weapon, to avoid the overhead of a call to mon_wield_item, but it turns out
