the idea with this character is that he must be able to critical hit ALOT and be dependable while moving constantly. I got help from the forums before but when I went to go search for the forum it appears it has been deleted. I know of one good feat that would help this guy (Darkstalker from LoM) but any other ideas would be good. Also equipment would be appreciated. Otherwise he is all up there. Thanks GITP and please do help me out here its for an epic level campaign and I need to get approval for all your advice before I can finish the build. Thanks again for all the help

Sorry tumble should be 12 ranks.

You don't want to run out of Dervish Dance movement, which can be a problem if enemies are spaced out. One good fix for this is some wings that let you fly at 2x land speed; that basically doubles your speed. Do you mind being Evil? Feathered Wings are a graft from Fiend Folio (page 210) which do that. As a graft they take up graft slots rather than magic item slots, and can't be stolen.

Anklets of Translocation let you move 10 ft. 2/day as a swift action. This allows you to move a tiny bit and still get a full attack action and, I believe, skirmish.
