You create a fist-sized, red-hot ball of molten metal that you immediately hurl as a splash weapon. A direct hit deals 2d6 points of fire damage. Every creature within 5 feet of where the ball hits takes 1d6 points of fire damage from the splash (Reflex half). Each of these creatures takes an additional 1d6 points of fire damage on its turn for the next 1d3 rounds, unless it is cooled off (with water, snow, or any effect that deals 5 or more points of cold damage).
