Final Fantasy Hacktics

Is there a way yet to make an ability deal constant damage? For example, the ability always deal 100 damage.

Yes, its relatively easy to do. I have a thread for asms, specifically for formulas. You may post in there and tell me what you want exactly and what formula you would want replaced. You can look at the formulas here and what ability uses them. http://ffhacktics.com/wiki/Formulas
