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?
Make sure the occasion doesn't say never. Other than that, I would recommend you post a screen-shot of the skill in the database and, if it isn't self evident from it's name, also tell us what it is supposed to do.
If a skill includes a weapon type (like sword or something to that effect) you need a weapon of that type equipped to use the skill, but other than that if the cost is zero then I can't think of any other reason why you wouldn't be able to use it.
