I recently asked Live Support what kind of skill the demon in Ember Army had, since I wasn't sure what he was doing, and if I could swap out my scatter heroes for someone else. They told me to ask on the forum for some reason, so here goes:
Each 5th wave of EA has a demon, but I have not noticed any type of animation to indicate a proc. Some suggest he stuns heroes, others say he removes buffs. Can anyone confirm this? Or does he not have a skill at all?
Thank you for your pleasant passion for our game.
