It’s a “Black hole” that temporarily sucks the enemy’s units in. Players quickly learned they can send in their units along with the enemies. So the trick is you send in a unit called the Archon which does splash damage. The split second that the black hole ends all the units emerge at the same time in a super concentrated area, so the Archon’s slash damage hits all the enemy’s units at once.
