Each time a piece of ammunition is drawn from this magic quiver, it is instantly replaced by an exact duplicate. Any pieces of ammunition removed from the quiver disintegrate after 1 minute.

The quiver can only hold one type of ammunition at a time, though the type of ammunition can be changed. Using an action to remove all 20 pieces of ammunition at once empties the quiver without duplicating any ammunition, but instantly destroys the removed ammunition.  Once the quiver is empty, a new piece of ammunition can be inserted, which instantly fills the quiver as it duplicates the new type of ammunition. If the ammunition is magical, its properties are also duplicated.
