Do you sure you have 5 minions collectively (of mages/archers/warriors/rogues) out when Abomination starts decaying?
For example: I have 3 Skeleton Vanguards, 1 Warrior, 1 Archer and 3 Mages and my Abomination doesn’t decay.
I could not reproduce this. Should to bring up a clip of it happening?
If it breaks or acts funky, feel free to post here again with a clip and I’ll look at it.
