Can you make a non-auto-cast ability auto-cast? I have tried with little sucess, or do I just need to use an auto-cast ability and have a trigger that creates a unit that can cast it?
I didn't understand that. You want to make a "Storm Bolt" (for example) auto-cast like a "Black Arrow"? I don't know if that is possible, but if I find out, I will tell you. Btw this should be posted in the Spells Forum.
Its imposiable to make an ability like Strom Bolt autocastable unless you make a dummy autocast spell and uses triggers to create a dummy and get it to cast Strom Bolt on the targeted unit.
