Phase 1

1. You must have your main tank enter first with everyone a good distance behind him because C'Thun does an EyE Beam ability that doubles in damage for each person to close to the inital hit.
2. Every 45 seconds Eye Tentacles will appear, these do a knockback and 750 damage. When the tentacles appear, you need to have all dps switch and kill them.
3. Dark Glare which is the red beam will move in a circular motion, 180 degrees around the room. Your raid needs to avoid this, it will instantly kill you.

Phase 2

1. This phase begins once you kill the Eye of C'Thun.
2. All players need to engage the stomach from the inside during this phase to bring down C'Thun's shield.
3. Every 10 seconds a tentacle will appear and swallow a random raid member. While in his stomach you need to kill the two Flash Tentacles inside. Making him vulnerable to your raid for 45 seconds.
