Description from original post (created 2016-05-14 13:53):
Above is the Vessel of Oryx
Light Eater Ogre:
The Light Eater Ogres are spawned when you jump on a pedestal when Oryx arrives. They must be killed quickly so that they will not destroy you all. They drop Corrupted Light, which you have to stand on when you stagger Oryx.
The Vessel spawns in a tomb ship and must be dunked on to steal it's aura of Immortality. It then must be killed because it WILL detonate those corrupted lights early.
