Counterattack

Fighting Style Feat (Prerequisite: Fighting Style Feature)

When you or a creature you can see within 5 feet of you is hit by another creature with an attack roll, you can take a Reaction to make an Attack against the offending creature and deal 1d6 of the damage type of the weapon you are wielding, which can be calculated using either your Strength or Dexterity modifier for both the attack roll and damage bonus. You must be holding a Simple or Martial melee weapon to use this Reaction.
