Revenge

You invoke a fight within to retaliate against a creature that damages you. As a reaction, when you are hit with a melee attack that deals damage, make a melee attack roll against your attacker, with disadvantage. On a hit, deal the same amount of fighting type damage back at your attacker (maximum of 5x your current level).

At Higher Levels: The damage dice roll for this move changes to 1d6 at level 5, 1d8 at level 10, and 2d6 at level 17.
