Dragonkind III
This spell functions as dragonkind II save that it also allows you to take the form of a huge dragon-like creature. You gain the following abilities: a +10 polymorph bonus to Strength, a +8 polymorph bonus to Constitution, a +8 natural armor bonus to AC, immunity to difficult terrain, blindsense with a range of 60 feet, a breath weapon, damage reduction 10/magic, frightful presence (DC equal to the DC for this spell), and immunity to one element. Your movement speed is increased by 10 feet. You also gain one bite (2d8), two claws (2d6), two wing attacks (1d8), and one tail slap attack (2d6). You can use the breath weapon as often as you like, but you must wait 1d4 rounds between uses. All breath weapons deal 12d8 points of damage and allow a Reflex save for half damage. Line breath weapons increase to 100-foot lines and cones increase to 50-foot cones.
