Insult to Injury

You are as skilled at striking one's pride as you are at striking one's body.

Once per round, when you hit a creature with a melee attack on your turn, you can use a bonus action to attack it with an unarmed strike. (As long as you are in range to attack it unarmed, and even if the initial attack was using a two-handed weapon.)

Option: If the bonus unarmed attack hits the target, the target must make a Charisma save of DC equal to 10 plus your Charisma modifier or be forced to use its reaction to immediately make an unarmed attack against you, if able.
