In Pillars of Eternity II, there are now subclasses (kits) for each class. E.g., Wizards can be Evokers, Enchanters, etc. These make the character more proficient with that school, but prevent them from casting from 2 other schools.
However, I've tried searching for which spells fall under which school, and I haven't found it. Neither the Official Wiki nor Fextralife have it. Which spells fall under which school?
