Whenever a creature fails a saving throw and takes fire damage from one of your spells, it catches on fire. This fire deals 1 point of fire damage per spell level at the beginning of the burning creature's turn. The fire lasts for 1d4 rounds, but it can be extinguished as a move action if the creature succeeds at a Reflex save (using the spell's DC). Dousing the creature with water as a standard action grants a +2 bonus on this save, while immersing the creature in water automatically extinguishes the fire. Spells that do not grant a save do not cause a creature to catch on fire.
