Roofwalker( CityScape, p. 63)
You are adept at moving and fighting on rooftops and ledges.
Roof-Jumper (Ci) ,
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 (PH 77), 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.
