When found, this pouch holds 4 stones the size of sling bullets. When thrown (range increment 10 feet), a stone from the bag of boulders instantly grows to the size of a light catapult stone and inflicts 3d6 points of damage. If the attack misses, treat it as a grenadelike weapon attack. Once all four stones are thrown, the magic of the bag is gone.
