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.

If you succeed on a Jump check when jumping down, 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 Defense against any opponent who is at a different elevation from you.
