Feral Glory Tattoo
The great predator or mighty weapon you' ve chosen as the subject of this tattoo of blood shifts across your skin an inch or two each time you use it, flowing around your body over the course of the years.
Wondrous Item 21,000 gp
When a nonminion enemy scores a critical hit against you and deals damage, you regain the use of the encounter power you gained from your Feral Might barbarian class feature (in other words, roar of triumph, swift charge, war cry, or whirling lunge).
