I’m chiming in to give a tip that hopefully will spare someone countless hours of futile work.
As a general rule, if there is an effect that is currently present only in enemy skill effects it doesn’t work for heroes, and vice versa. This means no riposte for enemies and no extra target chances for heroes. I’m 100% sure that heroes mind controlling enemies doesn’t work either. Heroes also cannot summon anything, even if one hero has already died.
