Poenir and Duenir, Malformed Demonic Aberrations

Strategy

A dual boss: Poenir, Rotten Wings of Despair, is the giant bat in the air while Duenir, Depraved Horns of Agony, fights on the ground, so an opening on one does not mean the other has stopped attacking. Keep moving and Wind Dash for space instead of standing to trade, and heal only after breaking away. Several players reported Poenir getting stuck in the ceiling or doorway, which a reload fixed.
