Overwhelming Mountain Strike

4th-level / Stone Dragon

You slam your foe with a mighty strike, knocking him from his feet and forcing him to find his footing and steady himself before he can react.   As part of this maneuver, you make a melee attack. This attack deals an extra 2d6 points of damage. If the creature you hit is standing on the ground, your attack reduced the targets movement speed to 0 until the end of its next turn and knocks them prone.
