omg i will explain it clear and simple
if an enemy stack is feared/sleeping/sheeped
YOU CANNOT control the stack BUT NEITHER CAN THE COMPUTER
what does this mean? that the HERO controlling the stack can't cast spells
since it will lose it's turn of the UNIT IMMEDIATLY(no control of it)
and when u cannot control u cannot cast spells
and in my example
the summoned unit from the demonologist. CANNOT BE controlled
so when the demoness SEDUCED IT(THE CPU COULD CONTROL MY EXECUTIONER)
and he CASTED A SPELL(which is a BUG)
and i'm not a level 5 unit user i hate em

^^
level 4 ftw
