This is a two phase fight, one with bouncing ball back and forth, and then an high damage phase.
Gracias a Sebte por las traducciones a español.
Split your melee players and your range player in two groups standing apart.
Soak and bounce the Void Diffusion "ball" between the groups.
When the Ball (Void of the Unmaking) touches a player, it bounces in the opposite direction, dealing large damage split between players hit.
It also gains a stack of Void Diffusion, dealing 20% increased damage on next hit, as well as making Zon'ozz take 5% increased damage (per stack) in the intermission.
If the Ball hits Zon'ozz, it forces him to phase, starting the intermission and resetting his stacks of Focused Anger.
IF TARGETED
MOVE OUT TO
GET DISPELLED
Stacking debuff on the boss, applies a stack every 6 seconds increasing his attack speed and damage done by 10%.
Hit Zon'ozz with the ball to force intermission and reset his stacks.
Intermission starts when Zon'ozz is hit by the "ball".
This is a high damage phase, stack up and heal through.
In heroic difficulty, adds will spawn during this phase.
