How much extra for a floating backpack with maybe air filled bladders taking up some space, my character is not a dummy it would be a good investment to keep some vital needs with her food rations and such.<br/><br/>My items currently is a masterwork quarterstaff that should float even if worked with some metal banding on each end and a proper grip, and a mithral shirt for armor. I have 1000 gp left so I figure she would have some things in a backpack designed to float with a cord tied to her. If she is a traveling fighter and merc she is not likely to risk vital items to water and the like. Plus the wizard folk might like a similar deluxe backpack for their books.
