Passive: +1 Constitution. Active: Activate this Shifter ability to shift your form, granting you a +4 Rage bonus to Armor Class and Constitution, a +2 Morale bonus to Fortitude saves, and a -2 penalty to Wisdom. When the form ends, however, you will lose the hit points granted to you by increased Constitution and become fatigued. Your form will last for 30 seconds plus an additional amount of time based on your Constitution. You can prematurely end your form by using the Dismiss Rage feat. This shares charges with Barbarian's Rage feat, and anything that grants bonuses while Raging will grant bonuses with this. Shifting your form in this way prevents Spellcasting, and prevents the use of other abilities that cannot be used while Raging.
