From D&D Wiki
Shifter Fury [Shifter]
When you shift and enter a raging state with it, there is seemingly nothing that can stop your vicious assault.
Prerequisite: Shifter with the longtooth or razor claw trait, ability to rage or frenzy.
Benefit: If you shift and rage in the same round you gain a +2 bonus to your Strength and Constitution scores, along with Damage Reduction 2/Silver stacking with other sources of damage reduction overcome by silver, until either your shifting and or rage ends.
