Pommel Strike

You can use all of your weapon to strike enemies. You gain the following benefits:

• When you take the Attack action and attack with only a greatsword, greataxe, or maul, you can use a bonus action to make a melee attack with the pommel of the weapon. This attack uses the same ability modifier as the primary attack. The weapon’s damage die for this attack is a d4, and it deals bludgeoning damage.
