It seems there's a bug when you put armor/weapons in storage. If you put an item with some composures used in storage, save and quit, and the retrieve it from storage, it has more composures, for example, I had the level 16 scimitar with 0 composures left, came back, and it had 11 new composures available. It's quite helpful when stacked with the 100% composure trick.
