Buff Bag

“A bag with a pocket for each kind of buff: a meal, a drink, a potion, a scroll, a gadget and a weapon (a blade oil or a field kit), up to 99 of each. Click it (or press B) and everything in it is used at once; anything already running is skipped, so nothing is wasted. Right-click it to choose what goes in each pocket. One per character; it can't be traded or dropped.”
