Azshradat

Azshradat, Celebrant of Xivu Arath is a Hive Knight commander serving Xivu Arath, the God of War. He led an invasion force to Titan to block Guardians rescuing Sloane, and is the final boss of the Salvage activity from Season of the Deep.

Salvage fight

After three jobs, fireteams descend underwater. Azshradat kneels inside an impenetrable dome while Hive reinforcements attack. Standing on the platform matching the central rune grants "Heinous Rite", which breaks the shields of Runekeeper Knights and Wizards that arrive in pairs. After two pairs fall he leaves the dome; his own shield uses the same rune mechanic and regenerates if you stop dealing rune-empowered damage, so keep rotating plates. Legend difficulty adds an Unstoppable Ogre.
