Polymorph (Small Fire Elemental)

The target creature becomes a small fire elemental. It gains a +2 size bonus to its Dexterity, a +2 natural armor bonus, resist fire 20, and vulnerability to cold. Its movement speed is increased by 20 feet. It also gains one 1d4 slam attack and the burn ability. Burn: A fire elemental deals 1d4 fire damage in addition to damage dealt on a successful hit in melee. Those affected by the burn ability must also succeed at a Reflex save or catch fire, taking 1d4 damage each round for an additional 1d4 rounds. Creatures that hit a burning creature with natural weapons or unarmed attacks take fire damage as though hit by the burning creature and must make a Reflex save to avoid catching fire.
