Shapechanger Bloodline (Bloodrager)

At 1st level, you gain the benefit of the Aspect of the Beast feat while bloodraging. As part of the action to enter a bloodrage, you can choose any one of the four manifestations to affect you for the duration of your bloodrage.

At 4th level, when entering a bloodrage, you can cast a transmutation spell that affects only you as a swift action, provided that the spell’s normal casting time is 1 round or shorter. The spell lasts for as long as you continue bloodraging, regardless of the spell’s normal duration. You can use this ability only to cast bloodrager spells you know.

At 8th level, you gain Aspect of the Beast as a bonus feat even if you don’t meet the prerequisites. As normal for the feat, you must choose one of the manifestations, and you gain its benefits even while not bloodraging. When you enter a bloodrage, you can choose a second manifestation to affect you simultaneously for the duration of your bloodrage.

At 12th level, when entering a bloodrage, you can cause your skin to grow thicker and more bestial. Your damage reduction from your bloodrager levels increases by 2, but it can be bypassed with silver weapons. Your natural attacks (including unarmed strikes) are then treated as silver for the purpose of overcoming damage reduction.

At 16th level, when your bloodrage ends, you can choose one spell or spell-like ability affecting you and attempt to shake it off as an immediate action. Attempt a dispel check (1d20 + your bloodrager level) as if you were casting dispel magic. If you succeed, the effect is dispelled.

At 20th level, you are immune to all transmutation spells and effects unless you are a willing target. You can also use greater polymorph at will as a spell-like ability with a caster level equal to your bloodrager level targeting only yourself. These effects function even while you’re not bloodraging.
