Kore's Blood

Darkness surrounds you. Your eyes turn completely black, your skin hardens and becomes gray. Finally shadows envelop your hands forming into long and sharp claws. 

Your subtype change into Outsider.

You gain an enhancement bonus to Strength, Dexterity, Constitution, and an enhancement bonus to natural armor. The exact values depend on your level and are listed in the table below. 

Your hands become claws, granting you two claw attacks, and your teeth becomes sharp as fuck, giving you a bite attack. You can attack with both claws at your full base attack bonus, but your bite attack takes a -2 penalty. Each claw deals 1d8 points of damage + your STR modifier, and your bite deals 2d6 points of damage + 1/2 your STR modifier and heals you for half of damage dealt. If your base attack bonus is +6 or higher, you do not gain any additional attacks.

You gain the benefits of the Blind-Fight feat as well as Darkvision. 

You can activate this ability as a swift action and the duration is 1 round/level per day. Not all rounds need to be spend at once. You can divide the duration as you please.

Finally if you strike a Critical Hit while transformed, you need to take a Will Save (DC 10 + damage dealt) or you fly into a rage. This functions the same as Barbarian ability of the same name except you must attack the closest being no matter if enemy or ally. Every following round you can attempt a Will Save with DC lowered by 5 (so after three rounds the DC is lowered by 15).

Special: If you are currently on Plane of Shadow, you gain an additional +4 to all the stats listed above.
