Roofwalker( Races of Destiny, p. 156)
You are adept at moving and fighting on rooftops and ledges.
The Roofwalker feat enables the use of three tactical maneuvers.
Fleet of Feet: You can walk across a precarious surface more quickly than normal. You can move at your full speed without taking a -5 penalty on your Balance check.
Graceful Drop: If you intentionally jump from a height, you take less damage than you would if you fell. If you succeed on a Jump check when jumping down (see page 77 of the Player's Handbook), you take falling damage as if you had dropped 20 fewer feet than you actually did.
Master of the Roof: You know how to use the slopes to your advantage. You gain a +1 dodge bonus to AC against any opponent who is at a different elevation from you.
