I have another question re: Learning and classes. Do they have to take the class in order to pick up the basics of one of the magics (by say, studying at the library), or would they just be more effective at learning it by taking the class? (for example: very basic Modifications and very basic Fantastics? I have Loki in Discovery/Sundering/Thaumaturgy as his morning classes. But he is very very smart and motivated to learn.)
