You and your mount can shatter an enemy’s line with your unyielding assault.
Benefit: On your turn you may overrun more than one creature. Each overrun combat maneuver check beyond the first has a cumulative –5 penalty. If you fail to overrun a target, your movement ends. Your mount may only make a single hoof attack against one target that is knocked prone by your overrun (not one per prone opponent).
Normal: You can only attempt one overrun per round.
