In my modified version she can use Drain Vitality (dragon) shout, has a healing aura, and is specialized on Lighting and Frost Spells. She can be quite OP to your liking so just tell me how you feel, I'll scale down.
The only downside of this follower (and others in general) is that you shouldn't give her any equip-able armors, she will equip those and you don't want that. I can't find a solution to solve that naturally, without relying on other mods. If anyon
