Barbed fire arrow

Tipped with an oil soaked rag and barbed point, this arrow deals an additional 1d4 fire damage and has a 25% chance (4 on 1d4) to light a flammable item which it lands in on fire. The barb will catch in wood or flesh, and must be snuffed or soaked rather than removed to be put out. If target is clothed, a success to light will deal 1d4 fire damage on the start of each subsequent turn until it is put out.
