Yeah this would be a neat late-game structure. Maybe there could be "nerd wizard" enemies that show up after the boss fight and have a higher chance of dropping spells.
Not sure, but I think it'd be funny if it were related to what the player wore. If a wizard hat was added in the future and you wore it, then maybe their tolerance for you attacking them (incidentally or directly) would go up before they retaliated, thinking that you were one of their own. Conversely, if you were wearing the Wawsp queen helmet, she'd call the wizards names when you got close to them, making them attack you on-sight.
