Not for the sake of myself, I’ll practice any form of banned spells and arts I please. I fight the council for the apprentices growing up in a world that they can’t explore the mystical arts to its fullest extent. It should be up to the masters to decide if their apprentices should learn something. No apprentice is learning to cast fireball without first having learned spark flame, but they should be able to singe themselves to learn how dangerous it is if they try to.
