History of Fear

Nightmare Hunt: Fear is one of the Nightmare Hunts released with Shadowkeep on the Moon, in which Guardians defeat the Nightmare of Phogoth, a Darkness-made copy of Phogoth, the Untamed, described as fear incarnate. Destinypedia places it at the Summoning Pits; ProGameTalk's walkthrough puts the path in the Hellmouth area, through the Gatehouse and the Circle of Bones.

Overview

Enemies are Hidden Swarm Hive (Thralls, Acolytes, Knights, Wizards, Ogres) and Nightmare variants. In the boss fight Phogoth becomes invulnerable periodically and summons reinforcements; ProGameTalk advises shooting the tumor on its chest and fighting adds from cover. Eris Morn frames Phogoth as a creation of Crota's brood.

Rewards

Defeating the boss gives the Essence of Fear quest; completing it earns a piece of Dreambane armor, plus XP and random gear (ProGameTalk). Sources disagree on player count (Destinypedia says 1-3, others describe a three-player activity). These sources date from the launch era; check in-game for current availability.
