During your build step, you may have one of your Bounter Hunters attack one of your other Bounty Hunters in the same arena. If you do, add X counters to this Resource, where X is the amount of damage done by that attack (after damage prevention).
Remove 5 counters Gain 2 build points, draw a card, and one of your Bounty Hunters gets +2 power and Fury 2 until end of turn. Play only during your build step.
