You've learned to put all your strength and weight behind each attack you make with your fists, letting its momentum empower your strikes, and improving your stance. You gain the following benefits:

• Increase either your Dexterity or Strength score by 1, to a maximum of 20.

• When you are hit with a melee attack you can use your reaction to retaliate with a counter, and make an unarmed strike back towards the creature within reach of you that injured you.

• Before you make a melee unarmed attack, you can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack's damage.
