Quivers

Quivers hold both arrows and bolts, they get placed into your Quiver slot. You can have multiple quivers in your inventory at once however only the quiver currently equipped will have arrows/bolts taken from it when firing a bow/crossbow. They can be set to automatically gather arrows/bolts when you loot, and the ammunition stored within them can be prioritized to select which ammunition stacks will be used first by moving the ammunition up or down within the quiver.
