I liked the section with the bimbo spell book and think it could be good to be able to toggle it on and off on yourself (Kinda like a "Hard mode") rather than just having a useless magic less spellbook. Also, I've found you're able to give both spellbooks when the vampire hunter mage comes back, it still triggers the bimbo book, but I feel like it should be a Game over to give the wrong (well technically speaking the right) one (Kinda like failing to give the octopus enough milk)
