Are you asking how to use dust to open someone up or how to use it in a combo? Cause you can use dust in combos but it has nothing to do with opening someone up. Good times to use dust are after a cS on block if you have meter to confirm it into a combo. When people air block your 2h in the corner it’s good to Fukyo in and dust them before they can see the dust come out since you’re a little off screen and coming out of a fukyo. Still have to meter to confirm though which is pretty easy for nago since he doesn’t use RC for a lot of his confirms so you’ll usually have a bar or more.
