Zalaj's Infinite Quiver
This magic quiver provides an infinite supply of arrows for any ranged weapon. Additionally the quiver charges the firer’s shots with electrostatic energy dealing an additional +1d4 electrical damage.
This magic quiver can be worn on the belt or slung over a shoulder. The mouth of the quiver is wide enough to stuff a composite bow and deep enough to store even a longbow, the quiver magically adjusts itself to whatever weapon the archer uses. Furthermore the magic of the quiver is such that any ammunition that is drawn fits perfectly to whatever weapon it is set to.
