Second boss in The Voidspire.
Boss is Static.
Bloodlust on Pull.
Boss/tank slam .. tank use defensive. Stacking debuff - taunt swap 2-3 stacks or when debuff falls off.
Expanding donuts - watch your timing!
Avoid walls from either left or right hand.
Adds spawn that fixate - kite and kill on top of the walls. Once an add (two on HEROIC) have died on a wall, the wall breaks, allowing safe zone from sweeping frontal.
Sweeping frontal that can go either left to right, or right to left, so both walls need to be down. Boss's glowing hand indicates where the frontal starts.
Watch your feet.
Healers watch out for raid wide ramping debuff (soft enrage)/knockback, and debuff from blister adds (dispel this)
