History of Servitor Eye

The Servitor Eye is the Void weapon of Deksis-5, a Fallen Servitor and the final boss of Exodus Garden 2A. Deksis fires Void blasts from its eye while two smaller Servitors give nearby Fallen reinforcements Ether immunity shielding. Deksis can levitate around the arena and occasionally teleport behind cover, and it is highly durable, so heavy weapons are the usual answer.

The same Servitor also appears as an extra boss in a story mission with Bakris, the Adamantine.
