Allright, so I ran the magic system throuh some of my players and they seemed interested in it. Thing is, I don't want to make changes in the base classes yet, but it seems to me the system was designed to work with the TB classes (and viceversa). I'm worried that by including the unified spell progression, including the bonus slots/ready spells gained by the different classes, I'll end up breaking the system/making them unbalanced compared to the other, unchanged clases. What do you reccommend? Should the USP be adopted only with the entire roster of TB classes?
