Hungering Destroyer

The Hungering Destroyer is a single phase "patchwerk" style encounter in which the raid must form small groups to help their allies heal up, as many people gain Gluttonous Miasma debuffs which causes them to become healing immune aside from leeching health from their allies. The boss has many mechanics which heal him, however these can be countered via good tank coordination and raid positioning!

The Hungering Destroyer is the second boss in the Catacombs wing, and is unlocked after defeating Huntsman Altimor. Defeating The Hungering Devourer unlocks Lady Inerva Darkvein.
