Ghost Blade

This spell temporarily transforms any wooden object that is longer in one direction than in another and of less than 35 lbs. or so (an average man-sized being must be able to lift it in one hand) into a sword. The sword can be of any one-handed type, from a short sword to a long sword, and is considered a magical weapon for purposes of what it can hit. It inflicts the normal damage of the weapon type selected (gaining neither damage nor attack bonuses from the magic), and can be wielded by any being as if she were proficient with it. The caster can cause the magic to end instantly before the spell duration expires. The wooden item-usually a staff, cudgel, furniture leg, or tree limb-is not consumed by the spell and reappears whole at the end of the spell duration even if the ghost blade was broken or bent during use.

The spell's material components are a handful of iron filings and a drop of water from any pool or body of water once struck by lightning.

Notes: Known to the Seven Sisters and some other wizards; rare.
