Simple, you go in settings and u find "auto cast ability" general automatically cast their skill, for example: Atreyos can automatically jump but cant call Clicky. The "auto cast ability" has 3 modes: ON, OFF, DEFAULT.
ON: Atreyos can use all of his ability automatically
OFF: Atreyos cant use any of his ability
DEFAULT: like now, Atreyos can automatically jump but cant call Clicky
PS. The funny thing is that it's not even OP, because do you know Archis? When he uses his abilities automatically but you didn't want him to do it? (Maybe because you were about to attack and Now you have to wait for the cooldown to recharge)
