4th-level / Stone Dragon
You are an implacable foe once you gain enough momentum. As you move across the battlefield, your foes must stand aside or be crushed beneath your feet. When you use this maneuver overrun attempts become a free action and you do not provoke attacks of opportunity until the of your turn. If you make an overrun attempt (DMG 272) while under the effect of this maneuver, you gain a +4 bonus on your Strength check made to overrun, and the creature takes damage equal to your initiator level. If you fail your check, your target can not be overrun again this turn.
