Knockdown Assault

Your unpredictable maneuvering puts your opponent off-balance—when you connect with your weapon they stumble and fall.

When you activate this maneuver, you take the Attack action and make a melee weapon attack, as well as any additional attacks granted by Extra Attack. Until the start of your next turn, when you hit with a melee weapon attack against a creature and deal 8 or more damage it makes a Dexterity saving throw or is knocked prone .
