Greater Wyrmshifter

Feats

At 20th level, a dragonblood shifter's tie to her draconic abilities reaches its peak. She becomes immune to sleep and paralysis effects. She can use wild shape at will to assume a new and final form. The dragonblood shifter becomes a huge dragon-like creature. She gains a +10 polymorph bonus to Strength, a +8 polymorph bonus to Constitution, a +8 natural armor bonus to AC, immunity to difficult terrain, a breath weapon, damage reduction 10/magic, and immunity to one element. Her movement speed is increased by 10 feet. She also gains one bite (2d8), two claws (1d8), two secondary wing attacks (2d6) (secondary attacks do not benefit from shifter claws), and one tail slap attack (2d6). Her breath weapon and immunity depend on the type of her dragon prototype. She can only use her breath weapon once per 1d4 rounds. All breath weapons deal 16d8 points of damage and allow a Reflex save for half damage. All breath weapons ignore energy resistances and immunities, and each has its own additional effect. Using dragon shape is a standard action that does not cause attacks of opportunity.
