Ciders... improved?

Well, most training parties include a priest or bishop, so a door could be provided most of the time to restock from storage for 4 hours of usage., and most soloable maps aren't packed with people, so you could come back to get your map back. Maxing out use and storage provides at least 48 extra non-cider slots for either use or storage purposes. Kind of depends on where you train and whether or not you usually have a priest/bishop in your party.
