Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods Add magic resistance to a class

Hello!

Long time ago I was playing some of Divinitys games, and I was looking for a good coop game, and I remembered Divinity.

So, Divinity Original Sin EE with some mods is a great idea.

But, after some time playing, I want to make the game more "strategic" and I start change class and spells to make each class really differents.
And I create some new class too.

But, there is one thing I don't know how to do, I want to add Fire Resistance to one of my class, and only to this class, to make a Pyro-witch who can heal themself with fire spells, etc etc. Adding more utility to magic groups, etc.

So, did you know how can I do ?
