Battle Fury

As a determined warrior, the fury of battle overtakes you in moments of disadvantage and weakness. When your health falls to 10 hit points or lower, you may add 1D8 to an attack or damage roll made with a melee weapon, or to a roll made on a strength check during combat, once per turn. This feature may be used a number of times equal to your constitution modifier. All uses are restored after a short or long rest.
