Nightmare Hunt

Nightmare Hunt is a three-player Shadowkeep activity on the Moon where Guardians fight "Nightmares", Darkness-made copies of old enemies such as Crota, Omnigul, Phogoth, Ghaul, Fanatic, Skolas and Taniks, released when Eris Morn disturbed the Pyramid. It has Adept, Hero and Legend difficulties, with Legend carrying six modifiers including locked loadouts. A Triumph named Harbinger relates to it.
