Xah'Rith the Keywarden of Terror, Tormentor of the Damned, is a Super Unique Morlu Caster located in the Stonefort in Diablo III, Act III. Xah'Rith is also a keywarden. He has a chance to drop the Infernal Machine. At levels 61-70, he instead has a chance to drop the Infernal Machine of War, and a small chance to drop any other level 70 device.
Like all other Incinerators, he can teleport around the battlefield and repel players who venture within melee distance (except his Repulsion inflicts a much more powerful Knockback). In addition, he has two more abilities:
- Illusionist: identical to the monster affix of the same name.
- Rain of Corpses: Xah'Rith's only real weapon, and his signature attack (replaces Meteor). Once every few seconds, he bombards a large area with frozen bodies, dealing heavy Cold damage, chilling enemies and leaving icepatches that deal Cold damage over time. All of his illusions will use this spell as well if not killed quickly, which can lead to a completely covered area of effect.
