Path of the Stampeeding Ram

A shephard walks besides his flock, observing how they play, how they fight, how they live... one of the young sheep challenges him... he smiles, taking a stance, he lowers his head towards it, accepting the challenge.

Ram's Concussive strikes

Just as the ram can knock others down, so can you! Your blows become concussive, Once per round on your turn whenever you make a melee attack and hit, you can force your target to make a strength saving throw or be knocked prone.

The saving throw DC is determined by 8 + Your Strength modifier + Proficiency bonus.
