KINNYTH'S PROFILE

Ok so Im having trouble with skills, Ive made a custom one and when I start the game it wont allow me to do anything with it. For test purposes Ive put it to 0 mana. Ive tried changing the mana cost. Do I need to add a sound to each frame in the battle animations? I just dont see why it wont work, any ideas?

Ive been working on a game recently were you are able to become enemies that you have defeated in battle. But Ive ran into a strange problem. When saved after becoming the other person the game crashes on a save...I use an event where I add a party member then subtract the other. Is there a work around or something Im at a loss and this is the main focus of the game, so please help.
