History of Nightmare Fallen

Nightmare Fallen are powerful Fallen summoned by Nightmare of Taniks during the Isolation Nightmare Hunt.

When Taniks drops to a third of its health, it becomes immune and summons Dregs, Vandals and Shanks protected by Solar Absorption Shields. When it reaches its last third of health, it becomes immune again and summons the Nightmare Fallen. The Nightmare Fallen must be killed before Taniks becomes vulnerable and the Hunt can be completed. Accounts of the final-phase adds differ: some describe Nightmare Fallen, while others describe a Nightmare Dreg and a Nightmare Shank.
