Mindless
- Not to be confused with brainlessness.
In NetHack, a mindless monster is any monster that lacks a physical brain and nervous system or a sufficiently analogous equivalent. Mindlessness is designated by the M1_MINDLESS flag in monst.h, which is checked for by the macro mindless(ptr).[1]
This is not to be confused with brainlessness, which is the result of a hero or monster having their intelligence drained by a mind flayer or master mind flayer.
Description
A mindless monster cannot pick up items unless they have the M2_COLLECT flag, and cannot use most amulets, any scrolls, any wands, any potions, or most tools that they come across, including items obtained prior to polymorph into a mindless form.[2][3][4] Weapons can be used by mindless monsters if they have a weapon attack, while they can only wear armor that they are generated with, though they will still pick up armor if they are flagged to collect items.[5]
Mindless monsters cannot be detected by telepathy, and are unaffected by the brain-eating attacks of mind flayers.[6][7][8] This protection does not extend to a hero polymorphed into the form of a mindless monster.[9] A mindless monster that is also breathless can safely wear an amulet of strangulation with no adverse effects, which also applies to a hero in the form of such a monster.[10]
