Upon casting this spell, the caster infuses the weapon touched with dark elemental energy. The next time this weapon strikes a creature, it discharges the dark elemental energy. The spell deals an extra 3 points of shadow damage per level (to a max of +15) + triple your Charisma modifier against the target of the attack. The weapon loses this property if its wielder drops it or otherwise loses contact with it.
