Is there any reason (PC only?) Tarquin couldn't have a bag of holding? While I'm sure he'd still keep a small hold out weapon like a dagger on hand at all times for use in the middle of a fight in case he lost his main weapon couldn't he have an assortment of other "main" weapons in a BoH so that he could quickly replace a lost one in between battles?

I'm just wondering since I play the various Final Fantasy/Dragon Quest games a lot and that's what I do. If my weapon is stolen or broken in a battle then as soon as that fight is done I equip a replacement.
