Drumlin Wall (3.5e Maneuver)

You carve a canyon through your enemies' ranks, leaving the results piled in a hill before you

When you initiate this maneuver, move your speed in any movement type you have except flying, in a straight line. Make a melee attack against each creature in front of you at the beginning of the move (any creature you get closer to, including moving from diagonal adjacency to orthogonal, or partial to more complete adjacency, for large creatures), and any creature you threaten as you move that you didn't threaten when you started moving. Each creature hit moves with you until the end of your move or it hits an immovable object or creature (including one that you do not hit over the course of the maneuver, but not one that you will hit but haven't hit yet), at which point it and the object each take 6d6 damage and it falls prone. You provoke no attacks of opportunity from anything you can attack over the course of this maneuver, and things you push likewise provoke no attacks of opportunity. At the end of the move, anything that moved to share its space with something else falls prone and takes 6d6 damage.
