MOVE TO EDGE BEFORE TANK BUSTER.

Spiritbreaker is the tank buster and it is a cast. Move to the edge during the cast and it will 1)leave a puddle on the edge and not under the boss and 2)wont shoot you to the edge anyways and 3)allow dps better uptime and less movement which makes the last boss way more enjoyable for everybody and 4)better totem placement for cleave/aoe.

Because its a cast, you can freely move away from boss to edge, take final hit and then use a movement speed to get out of puddle with little to no movement of the boss for your dps. better dps uptime, faster boss goes down.

I have tanked and dps this boss and it's easy as hell if the tank moves out for tank buster and drops puddle away from boss.
