hehe poor guys, they still dont get it
use the secondary attack key to throw the saber about 10 feet from you (GAME feet, dont hold the button down until you can barely see the saber
then when you're about to catch the saber quickly tap back, then right, then forward, then left. it should take you less than 2 seconds to finish that sequence. just keep on doing tapping back-right-forward-left to keep that saber going around you. very cool eye candy, and really easy to do.
i have a question about this attack too, but i'll start a new thread for it.
oh, and no you dont need a certain level to do this trick. i think it consumes force power but it does so very slowly and even when you're down to your last bar of force you can still do it.
