Fire arrow

In developing the fire arrow, dwarven tinkers took the expertise with gunpowder they gained developing rifles and rockets and turned it toward the bow and arrow. The fire arrow isn't itself an arrow. Instead, it's a small cylinder that attaches just below the arrow's head, with a short cord attaching the cylinder to a ring on the archer's quiver. When the arrow is fired, the cord ignites the charge inside the cylinder and propels the arrow incredible distances.
