Azshrūnah ur-Nokru, the Sacrificed is a Taken Knight of the Ultra rank and the boss of the Blooming Deep Lost Sector in the Pale Heart. It first appeared in Destiny 2: The Final Shape.

Encounter

The fight plays like an ordinary Taken Knight encounter, but it calls up groups of Taken as reinforcements. It creates a Taken Blight and summons more Taken at the start of the fight and again when it loses two-thirds of its health. Defeating it unlocks the cache code that Guardians use to claim their rewards.

Its listed weapons are Stasis and Howler, and its abilities include Taken burn, teleportation, rapid movement, and summoning Taken and Taken Blights.
