Vrhiisk, Seeker of Power

Vrhiisk, Seeker of Power is an Omen of the Witness that commands a Dread detachment. It first appears in Destiny 2: Heresy and is the first boss of the exotic mission Derealize, fought in the Mausoleum. It seeks a source of immense power and turns on its own Dread soldiers to ally with the Dire Taken.

In the first phase Vrhiisk raises an immunity shield and summons six Blight Sentinels. Killing them spawns Taken Conduits that yield relics; a relic gives the Torn Between Dimensions buff, which is used to destroy a Taken Blight and drop the shield. The shield returns in a second phase and the same process is repeated before the boss is defeated.
