Book of Shadows: Black Bag

This spell creates a bag full of knives, scalpels, surgical equipment and other small torture implements. If the implements are removed from the bag by anyone other than the caster, or if they leave the caster's possession after he removes them, they disintegrate after 1 round.
The bag and its magically created contents weigh only 1 pound. Evil magic items, including items that deal unholy damage, and items with an unholy spell as a prerequisite for their creation can be placed in the bag as if it had 10 cubic feet of space. These additional items add no weight to the bag. Non-unholy items added to the black bag fall through as if the bag had no bottom, so they cannot be stored in the bag.
