Grava'Thul, the Voiddrinker

Grava'Thul, the Voiddrinker Is a Nemesis Spawn of the Chthonians faction.

He is an Ultra Boss of Grim Dawn so the player must be prepared for that encounter.

Family: Chthonians

Genus:

Spawn Points

 * Mourndale
 * Cinder Wastes
 * Fringes of Sanity
 * Desolate Wastes
 * Void's Edge

Grava'Thul will, most likely, only spawn in Act 5 and Act 6 areas where Chthonians spawn, so the Ashes of Malmouth expansion is required.
