I'd noticed a lot of certain races of followers have really low magic caps. I think this could be changed in the game by adding an alchemy potion that could raise the limit of the magic cap. But make it hard to get and expensive so that the game's initial quality of working for stats is preserved. 

Thanks. 

The game has ceased development, but maybe someone will make a mod for it. Personally, I don't think magic caps need to be raised as magic is already incredibly overpowered. If you didn't know, the game already has two methods of increasing the magic cap for slaves by 2 each, though one of the methods is stupidly expensive.
