Frost: Upon command, a frost weapon is sheathed in icy cold. The cold does not harm the wielder. The effect remains until another command is given. A frost weapon deals an extra 1d6 points of cold damage on a successful hit. Bows, crossbows, and slings so crafted bestow the cold energy upon their ammunition.
