Witch magic is as natural as any other skill, when you mess up using your magic its the same as dropping a plate. Some witches can fly and others can’t and some can make plants grow and others can turn into cats etc. Wizards lock themselves up in their big book towers and study and study and study and learn magic through theories and spells. When wizard magic messes up it’s like having your chem experiment explode. You just work on another theory till it works.
and wizards are way rarer than witches, witches find them pretty weird.
