Magic Weapon Abilities - Spell Storing
A spell-storing weapon allows a spellcaster to store a single targeted spell of up to 3rd level in the weapon. (The spell must have a casting time of 1 action.) Any time the weapon strikes a creature and the creature takes damage from it, the weapon can immediately cast the spell on that creature as a free action if the wielder desires. (This ability is a special exception to the general rule that casting a spell from an item takes at least as long as casting that spell normally.) Inflict serious wounds, contagion, blindness, and hold person are all common choices for the stored spell. Once the spell has been cast, the weapon is empty of spells, and a spellcaster can cast any other targeted spell of up to 3rd level into it. The weapon magically imparts to the wearer the name of the spell currently stored within it. A randomly rolled spell-storing weapon has a 50% chance to have a spell stored in it already.
