|A terrible liminal demon, a horrific fallen divinity, a mane of grasping claws and jaws of gnashing stone in a necklace of starry organs and a skirt of wiry bones. Formed waiting for the auspicious days when they will devour the sun, the astral skeletons tzitzimitl spread disease and incite despair.|
Tzitzimimeh are one of the most versatile among demons, posing a threat to characters whether they're living or undead. While negative energy and cold resistance helps reduce the effects of most of their attacks, torment and Dispel Undead always sting. They can be found in Pandemonium and the Hells (primarily Tartarus), and some monsters may summon them with the Summon Greater Demon spell.
Tips & Tricks
This is the only fiend against which being undead does not protect - in fact, it is possibly more dangerous to be so, given that Dispel Undead deals as much damage as Iron Shot but bypasses AC, EV and any resistances. If you are a lichform caster, consider letting it wear off if you can't kill these quickly, i.e. in two or three turns. If you are naturally undead, keep them at the edge of LOS or behind other monsters and pelt them from afar with ranged attacks - wands of fire can be effective. Fortunately, their multiplicity of spells makes them torment considerably less often than other fiends, and having rN+++ greatly reduces the threat they pose. Use a holy wrath weapon or high-powered non-elemental conjurations to dispatch them, for they have no specific vulnerabilities.
Prior to 0.18, they were called Shadow Fiends, who lacked miasma attacks and had less HD.
