Lore[]

Zolthrax
The Culler of the Twice-Damned patrols the pits of anguish, eliminating any demon warriors it deems inadequate with a swing of its boiling blades. Rumor holds that Zolthrax was once among their number: a faceless, identical wretch before it offered up scores of its fellows in tribute to the Abyssal worm below.[1]
In-game[]
Zolthrax appears as the second miniboss of the Pit of Anguish dungeon in Diablo Immortal. He is also seen as a boss in Path of Blood, where he appears as the boss of floors 5 and 95.
