A storing weapon must be a missile launching ranged weapon such as a sling, crossbow, or bow. A weapon enchanted with this type of magic can store up to 50 projectiles in an extradimensional space tied to the weapon’s launching mechanism. The user need only fit the projectile to be stored into the weapon and concentrate to store the projectile in this extradimensional space doing so is a standard action. The user can retrieve a projectile from this space by preparing to fire the weapon and concentrating on the missile to be fired. If different types of missiles are stored in the weapon, only the projectile concentrated upon by the user is conjured forth. Calling forth a projectile to be fired upon is a free action. Crossbows enchanted with this magic need not be manually loaded during the heat of battle, and as a result the user may use all of his attacks with the weapon as a full round action.
If a weapon of storing is placed within a portable hole, bag of holding, or similar extradimensional space, the weapon of storing is destroyed and all of the stored projectiles inside are expelled violently in a 30 foot burst. This explosion of projectiles does 1d6 points of damage per five projectiles released in this manner to all creatures in this area; a Reflex save (DC 15) halves the damage done. All the projectiles are destroyed in this explosion.
