Warwatcher

Warwatcher, Eye of Xivu Arath, is a powerful Hive Shrieker and commander in Xivu Arath's Horde. It is the final boss of Heist Battleground: Europa, introduced in Season of the Seraph. In the mission it was sent into the Yggdrasil Stack, a Seraph Bunker on Europa, to merge with its mainframe and steal data on the Submind frameworks.

Fight

At half health the Warwatcher closes and Wrathborn with Arc charges spawn. Defeat five of them and deposit their charge into the center pillar to force it open again. Each teleport to a new location costs it a sixth of its health. The battlefield is swarmed with Wrathborn, Fallen and Hive throughout.
