As an action, make a weapon attack to knock the creature back.

On a hit, add the stamina die to the attack’s damage and if the creature is your size or smaller, it must succeed on a Reflex saving throw or you push it 4 meters away from you.

On a critical hit, add twice as much damage.

On a miss by 4 or less, add half as much damage.

Enhance

You can increase the damage, push the creature an additional meter, and target a creature of a larger size for each additional stamina die expended.
