Sudden Leap(Tome of Battle: The Book of Nine Swords, p. 89)
Tiger Claw (Boost)
Level: Swordsage 1 (One Tiger Claw maneuver), Warblade 1 (One Tiger Claw maneuver),
Casting Time: 1 swift action
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. 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.
