Sudden Leap p. 89
You leap to a new position in the blink of an eye, leaving your opponents baffled.
You can make a Jump check as a swift action and move the distance determined by your check result. This Jump check follows the normal rules for Jump checks, and has a higher DC if you do not have a 20ft running start. You provoke attacks of opportunity with this movement, and you must move in a straight line. As with any movement, you can attempt a Tumble check to avoid any attacks you provoke with this sudden leap. You can't move through enemies, unless you succeed on the appropriate Tumble check.
