|Location||Assault on Violet Hold|
Black Bile is a Level 111 aberration spawned by Festerface in the Assault on Violet Hold instance on Heroic and Mythic difficulty. It is summoned upon Festerface reaching 100 energy and using the Uh Oh ability.
- Killing one of these during the encounter and then killing Festerface on Mythic difficulty earns the achievement
- Patch 7.0.3 (2016-07-19): Added.
