Humanoid is a monster type in ADOM. Humanoids are a diverse class of monsters that are at least semi-intelligent, capable of some sort of speech, and know how to equip, use, and throw items. Construct humanoids — e.g. golems — are an exception. Humanoids probably make up the largest group of monsters in ADOM, making humanoid slaying weapons particularly desirable.
The monster class consists of several monsters including humans ('@'), small humanoids ('h'), grungy humanoids ('g'), orcs ('o'), minotaurs ('M'), ratlings ('r'), kobolds ('k'), berserkers and barbarians ('K'), townsfolk ('t'), trolls ('T'), werebeasts, presumably giant humanoids ('O' or 'H'), and possibly demons ('&').
Arrows and quarrels (and sling bullets as of 1.2.x) of humanoid slaying exist, which, due to the nature of critical hits with missiles, guarantee three to six times normal damage against humanoids.
Most humanoids are susceptible to Phial of Caladriel (except of construct humanoids?)
Humanoids can be 'C'hatted with, and are capable of using items in a number of ways. As at least partially intelligent creatures, all non-construct humanoids can be affected by mindcraft
