Tuns
Tuns are a shopkeeping item recently introduced to allow shop owners to sell elixirs, salves, venoms, and other various fluids without the need to also sell pre-filled vials. In many ways, a tun replicates the way Seasone refills vials.
Tuns can be purchased from Fronck in the Delosian Furniture showroom for 200,000 gold sovereigns. Like libraries, Fronck will then give the shopkeeper a tun designator which they may then drop in the stockroom of their shop. Tun designators may be picked up by the shopkeeper that dropped them, and multiple designators may be dropped in a single storeroom, limited only by the remaining space therein.
A tun will hold a quantity equal to 100 'superfilled' vials. Regardless of how empty or full a vial is at the time one refills it from a tun, the same price that the shopkeeper put on a refill will be charged and the vial will be fully filled to 200 sips for concoctions and 150 sips for venoms.
