As a bonus action when you hit a creature that is your size or smaller with a weapon attack, you can drive the target back. The target must make a Reflex saving throw.
On a failed save, add the stamina die to the attack’s damage roll and you push the target up to 3 meters away from you.
On a successful save the target takes half as much damage, but isn’t pushed.
You can increase the damage and target a creature of a larger size for each additional stamina die expended.
