Ive been working on this very complicated map (not hard to make but much to make) and I have something called faith (how much the people belive in the king) I need to make a spell that charms random units based on the faith lets say that you have 50 faith and a spell that has a 70% chance of converting units in an area then the chance of converting becomes 20% (I dont want a 20% chance of ALL units being charmed I want all to be randomised) Is this possible? If it is pleace tell me how to do it (tell me every step Im not so good at spell making)
