Vengeance

reaction
 You swiftly retaliate for those under your protection. When a creature adjacent to you uses an action to deal damage to someone other than you, you can use your reaction to make one melee weapon attack or unarmed strike against that creature.
 If you you damage the creature, the first time that creature makes an attack roll targeting anyone but you within 1 minute, roll the vigor die you expended on this technique. Subtract the result from the creature's attack roll.
