Nana's rabbit guard should probably reduce the stacks by 2 to counteract the passive +1 per turn. As for the whole "buy a weapon or magic" bit, maybe those shops should be locked until after the rabbit den with a few new lines during that part of the tour. Also where is the Kitsune form?
Ex. for the weapon shop: "It's unfortunate you arrived today instead of tomorrow. The shop keep's shipment got delayed and won't be arriving until later. Luckily your non-human forms have natural weapons so that won't be as much of an issue."
Ex. for the magus': "I heard he/she got a bunch of tomes recently, so I doubt he/she will be seeing anyone at the moment. Maybe you should check back after your investigation of the rabbits. For now, I recommend you stock up on herbs and potions instead."
