Through or Tumbling Strike, and you successfully moved through an enemy's space. You use a burst of stamina to perform a breathtaking feat of Acrobatics as you speed through a foe's space, leaving your foe lying flat on their back. You attempt to Trip the enemy whose space you moved through. You can use Acrobatics instead of Athletics for this check.
