Walking the Way: A Swordsage's Handbook [Under Construction]

[Greenish]

Sudden Leap - Even if you have no investment into Jump, this is ~10' swift action movement

If you've no investment in Jump, you'll need quite a high strength to make DC 20 check with any reliability.

That reminds me, an item most swordsages will want is the Boots of Agile Leaping from MIC, which allow you to use dex instead of str for Jump checks, and you can stand up from prone as a swift action. That's quite a bargain for 600 gp.
