Nightmare Hunt: Isolation

The Nightmare is the boss of Nightmare Hunt: Isolation, set in the Temple of Crota. It fires a Scorch Cannon, teleports and uses an Ultra Smash at close range, with Fallen and Major Nightmare reinforcements joining the fight.

• Phase 1: at one-third health it becomes immune, summons Dregs, Vandals and Shanks protected by Solar Absorption Shields, and retreats deeper into the area.
• Phase 2: it leads the fireteam to the Traitor's Ketch lift, into a smaller arena where cannon explosions are harder to dodge. At one-third health it becomes immune again and summons powerful Nightmare Fallen, which must be defeated before it can be damaged.
