History of Kra'lok

Overview

Kra'lok, the Sword is one of the twin Nightmares of the Scorn that guard a Haunted Alcove in the Pleasure Gardens on the Derelict Leviathan. He is paired with Ha'lok, the Shield, and the two first appeared in Season of the Haunted. Destinypedia lists Kra'lok as a Solar Scorn Chieftain of Ultra rank, and describes him as the tankier of the pair.

Encounter

A message reading 'A sword and shield clash together...' signals that the pair can be found. Players climb rocks near the entrance from the Castellum to reach the alcove, where a Nightmare Raider waits at the end of the corridor. Once that enemy notices the player, a second message warns that the Nightmares are fading, so the room must be cleared quickly or they despawn.

Waves of Nightmare Raiders, Lurkers and weaker foes come first. Once enough of them are defeated, Kra'lok and Ha'lok appear. Both are very hard to damage, but the lesser enemies drop Unstable Essence on death, which makes attacks against the Sword and Shield more effective.

Rewards

Defeating both Nightmares before they despawn opens a chest with loot and earns the Nightmare Breached triumph.
