Hierarch

Hierarchs are elite Hive Wizards of Savathûn's Brood. The Ritual Hierarch in Siren Song levitates, summons Hive reinforcements, and attacks with Arc darkness blasts, a Solar absorption shield, and a Kinetic cloud of darkness.

The Hierarchs carry out a ritual with the Knight Nalcthor, the Crystaline, to sink the New Pacific Arcology. The ritual centers on a large Hive Crystal beneath the Arcology, which Nalcthor sings with. Each Hierarch appears when a Hive shrine is destroyed. Destroying the shrines, killing the Hierarchs, defeating Nalcthor and removing the Crystal stops the ritual and the gravity waves that were destabilizing the Arcology.
