– Add Phase: Dedicate someone to each circle; CC 3 mobs and kill the rest, interrupt their heals.
– Boss Phase: When he casts Blast Nova, click the square box you’re assigned to. Click once during cast (channeling is fine too) but NOT before he starts casting. Once the cast is interrupted, you are free to stop casting on the cube and can resume fight.
Tip: If you have enough gear, you can heal through the blast nova.
Note: The cubes do not leave a debuff on players meaning there is no restriction to how many times a player can click a cube during the encounter.
