It partially works, anyway to tell the lesser power to make so it cant be casted right after its been casted? want to give it a 30 seconds cool down.
I don't know, that seems like some kind of game setting or global variable, and I think it affects all lesser powers. They are all re-cast after about 6 seconds. If you turn godmode on, they are all re-cast instantly.
If you find where to change that, I would like to know.
But you could also make a cooldown script effect which removes it from the owner for x seconds when you cast it, then adds it again.
