SRD:Flaming

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