Second boss in The Voidspire.
Boss is Static.
Avoid walls from either left or right hand.
Watch out for sweeping frontal from wall location to wall location.
Expanding donuts - watch your timing!
Adds spawn that fixate - kite and kill on top of the walls. Once two adds have died on a wall, the wall breaks, allowing safe zone from sweeping frontal.
Sweeping frontal can go either left to right, or right to left, so both walls need to be down.
Watch your feet.
