For example, if you want to play as a dual wielding rogue and Searing Daggers sounds fun in your repertoire, it would previously have been a useless spell damage-wise, but now the damage will scale of Finesse instead of Intelligence! This mod changes the stat from Intelligence to the stat of your primary equipped weapon. Without this mod, spells like Searing Daggers scale based off how many points you have in Intelligence, your level, and how many points you have in Pyrokinetic (amongst other things). It changes the way some of the non-weapon spells in the game work.
This is the only mod I have ever made, but I heard it might be popular so I thought I would upload it for others here to use at their leisure.
