As the world fades around you, the sting of defeat washes over you. But a primal defiance erupts within, a refusal to yield to death. You roar in defiance, channeling the last embers of your rage into a surge of healing power.
When you drop to zero stamina and take any hit points of damage, you may expend all your remaining Rage. You recover 1d8 points of damage for each Rage spent in this manner. Once you use this ability, you cannot use it again until you complete a long rest.
Remember that healing is applied first to stamina, and only when your stamina is fully recovered is it applied to hit points.
