Spit Fire (Su): A dracotaur can spit a glob of fire as a standard action. Once a dracotaur spits, it cannot spit again for 1 minute. The dracotaur's spittle is a sticky adhesive substance that ignites when exposed to air, much like alchemist's fire. This glob of fiery spittle is treated as a ranged touch attack with a range increment of 20 feet.

A direct hit deals 2d6 points of fire damage. Every creature within 5 feet of the point where the spittle hits takes 1d4 points of fire damage from the splash. Unlike alchemist's fire, a dracotaur's spittle does not continue to burn.

Skills: Because of their tails, dracotaurs have a +4 racial bonus on Balance, Jump, and Swim checks.
