Imperator Averzian
The objectivePrevent three rifts from lining up on the tiled floor.
Where to stand
Stay with the group on a clear tile. When the large circle appears around the tank, move in even if you normally attack from range.
During the large circle
The tank centres the circle on the chosen Voidshaper. Everyone enters before it explodes.
The fight in order
Choose two Voidshapers
Three Voidshapers appear. Normal attacks barely hurt them; use the tank’s circle explosion to destroy them. Agree in advance which tile can hold the third rift.
Share both explosions
The tank moves the large circle onto the first chosen Voidshaper. Everyone enters before the explosion to share the damage. Repeat at the second Voidshaper with the next circle.
Kill the reinforcements
Tanks swap and the group kills enemies coming from the rift. On the next wave, do not leave a third rift in the same row, column or diagonal as two existing rifts.
