Polymorph, Greater (Brass Dragonkind)

You are in a dragon-like creature form now. You have a +4 size bonus to Strength, a +2 size bonus to Constitution, a +4 natural armor bonus to AC, immunity to difficult terrain, a breath weapon, and resistance to fire 20. Your movement speed is increased by 10 feet. You also gain one bite (1d8), two claws (1d6), two wing attacks (1d4), and a breath weapon ability. You may choose to resume your normal form as a full-round action; doing so ends the spell for you. Breath Weapon: Your breath weapon deals 6d8 points of fire damage in a 60-foot line and allows a Reflex save for half damage. You can only use the breath weapon once per casting of this spell.
