Frenzied Rager

The bamboo highlands are home to the bloodthirsty kitsune hordes.  The most elite of these are fanatically devoted to the kitsune god of love and madness: Tsukio
Prerequisite: Kitsune
The following are class features of the frenzied rager:
==== Chosen of Tsukio (Ex) ====
A frenzied rager has been chosen while in the womb to be a paragon of Tsukio on Tibaeria.  As such, they have been taught to revere only Tsukio, and their alignment must be within one step of Tsukio’s.  Furthermore, all frenzied ragers must have the fast shifter racial trait.
==== Frisky (Ex) ====
Whenever a frenzied rager changes to kitsune or fox form, he may substitute his dexterity for his strength to determine damage done with any weapons that qualify for the weapon finesse feat until the beginning of his next turn. Additionally, the frenzied rager gains the following feats even if he does not meet the prerequisites.
At 2nd level, the frenzied rager gains Fox Shape as a bonus feat 
At 6th level, the frenzied rager gains Swift Kitsune Shapeshifter as a bonus feat
At 10th level, the frenzied rager gains Vulpine Pounce as a bonus feat
This ability replaces the rage powers gained at 2nd, 6th, 8th, and 10th levels.
==== 9-Tailed Berzerker (Sp) ====
At 3rd level, a frenzied rager begins growing additional tails as a sign of Tsukio’s favor and power.  Each tail contains a boon from Tsukio which can be used once per day as a swift action (or immediate if noted in the spell description) even while raging. The caster level is equal to the frenzied rager level, and the save DCs are dexterity based. 
3rd: Windy Escape
5th: Cheetah Sprint
7th: Cat’s Grace
9th: Mirror Image
11th: Fire Trail
13th: Paragon Surge
15th: Detonate
17th: Damnation Stride
19th: Cruel Jaunt
This ability replaces uncanny dodge, improved uncanny dodge, and damage reduction
==== Rabid (Ex) ====
At 4th level while raging, the frenzied rager gains two claw attacks that deal 1d4 damage. These attacks are considered primary attacks and are made at the frenzied rager’s full base attack bonus. 
This ability replaces the rage power gained at 4th level.
