Kitsune

Kumiho Form (Su): At 1st level, you fall on all fours and transform into a terrifying fox-like magical beast when you enter your bloodrage, as beast shape I except you do not gain a Strength bonus or natural armor bonus to your AC. In this form, you are a Medium quadruped creature and gain low-light vision, scent, and a bite attack that deals 1d6 points of damage. At 4th level and every 4 levels thereafter, you gain a +1 natural armor bonus to AC while bloodraging.

Kumiho Spellcraft (Su): At 4th level, you can complete the verbal and somatic components of bloodrager spells while transformed while using kumiho form. You substitute various noises and gestures for the normal verbal and somatic components of a spell. You can also use any material components or focuses you possess, even if such items are melded within your current form. This power does not permit the use of magic items while you are in a form that could not ordinarily use them, and you do not gain the ability to speak while transformed. Additionally, the Spellcraft DC to identify spells that you cast while transformed increases by half of your bloodrager level.

Heart Strike (Ex): At 8th level, when you attack an opponent with a bite attack as a standard action using the attack action, your bite has a critical multiplier of x3 and you deal additional damage equal to your bloodrager level. Any creature immune to sneak attack damage is immune to the extra damage done by this power and any item or ability that protects a creature from critical hits also protects it from this extra damage. The damage done by this power is precision damage and isn’t multiplied on a critical hit.

Improved Kumiho Form (Su): At 12th level, the damage dealt by your bite attack increases to 1d8 points and you gain the trip special attack with your bite attack. At 16th level, the damage dealt by your bite attack increases to 1d10 points. At 20th level, the damage dealt by your bite attack increases to 2d6 points.

Heart Snatch (Su): At 16th level, you can use your kumiho form’s improved senses to help fell your opponent with a single strike by ripping its still-beating heart from its chest. This ability functions as the assassinate master ninja trick except it applies to the precision damage caused by your heart strike power instead of sneak attack damage.

Kumiho Paragon (Su): At 20th level, all enchantment, illusion, and transformation spells you cast with a duration longer than 1 round are extended, as Extend Spell.
