Damn progressives always wanting to change things. Leave it as it is!
(This has nothing to with the fact that
a) I am leveling a sorc and want to fry you all
b) Find this entire system bonkers. If I cast a fire ball at you, you either get it, or not. Which is a function of your AGI. If I strike a hit, if you have a good armor (AC) you wont fry. If you are wearing clothes (low AC) you fry.
In other words, this shouldnt be different than any other form of combat.
My own base damage should be a function of how intelligent. After all, since I am a genius I will cast a giant fireball.
Fizzle should be (if not already) a function of my wisdom. As I am very wise, i never f*** it up.
