Hi,
Adding probabilities to spells might be a fun and interesting way to improve your spell casting skills. By this, I mean that when you first achieve a spell, the success that it will cast properly is 50%, but every time you cast it, the chance gets higher with a maximum of 99%. Then players will have to "train their spell casting" (just like you would in real life) to cast spells successfully by casting them over and over again. I think this would be an interesting feature because it adds a realistic feeling of spell casting, now you wouldn't just be able to be a professional at spell casting, but you would have to become good at it instead.
