The minotaur priestess is a spellcasting version of the common minotaur, added in dNetHack. The priestess shares the regular minotaur's 2d8 head-butt melee attack, but attacks with clerical spells instead of the additional claw attacks.
Although they can use magic, minotaur priestesses are not considered intelligent enough to use unicorn horns, amulets, potions of gain level, or unlocking tools.
Minotaur priestesses are only randomly generated in Gehennom. As servants of the demon lord Baphomet (like regular minotaurs), several will appear on his level, if it appears.
The minotaur priestess also appears in Slash'EM Extended and SLASHTHEM.
