How often does Overgrowth's cleanse proc?
I don’t think it affects players outside of their third of the map.
It does. As long as they hold the points.

It will affect players that are in the overgrowth part of the map, and around the 2 outer branched out towers. it doesn’t go into frost’s territory or badlands’s territory is what I’ve noticed. I could be wrong.
