Oversoul

An Oversoul is a Hive construct that lets Ascendant Hive separate and hide their souls from their bodies: "If we can separate our deaths from ourselves, and hide them, we will be hard to kill." It protects the soul and releases a lethal death impulse. Crota's Oversoul is the enrage mechanic of his fight in Crota's End, Oryx's Dreadnaught functions as his Oversoul, and the Oculus is the Warpriest's variant in King's Fall. See also Oversoul Edict.
