As an action, make a melee weapon attack against a creature after you move at least 3 meters straight toward it.
On a hit, add the stamina die to the attackās damage and if the creature is your size or smaller, the creature must succeed on a Reflex saving throw or you can push it 2 meters away from you and knock it prone.
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, target a creature of a larger size, and push the creature an additional 1 meter for each additional stamina die expended.
