History of Nightmare of Gahlran

Nightmare of Gahlran is an activity entry tied to the Duality dungeon from Season of the Haunted (May 2022), categorised as a Nightfall in the game data, set on the Derelict Leviathan and using Duality's art. It refers to the dungeon's first boss, Nightmare of Gahlran, Sorrow Bearer, a Nightmare copy of Gahlran, the Sorrow-Bearer created by Emperor Calus.

Overview

• Type: Nightfall entry in the game data; the boss itself belongs to the Duality dungeon.
• Destination: Derelict Leviathan. Sources place the Duality dungeon itself on the Moon, entered via the Derelict Leviathan. Duality needs the The Witch Queen Dungeon Key and the quest "A Single Thread" from Suraya Hawthorne.
• I could not confirm a standalone playable Nightfall of this name; the reward list below is what the game data attaches to the entry.

Encounter mechanics

Gahlran is immune until two Standards are taken from Standard Bearers in the Nightmare realm and placed in the Waking World. Guardians then clear the opened rooms and kill the Visions of Gahlran in the Nightmare. After that he turns vulnerable, teleports to the arena centre and becomes aggressive. He uses Solar-corrupted Hive weapons and summons Cabal Legionaries.

Rewards

The game data lists Adored, D.F.A., Lotus-Eater, Mint Retrograde, Null Composure, Ouster Engine, Salvager's Salvo, The Hothead, The Palindrome, The Slammer, Whatchamacallit and Eutechnology armour. These are not verified against the dungeon's loot.
