There was a setting (now that I think of it) that was called "Dustlands" or something here on these boards. Was post-appocalyptic (literally, the final battle between Heaven and Hell had come and gone, everything on the prime material was SUPPOSED to have gone to its final reward/judgement/whatever but some people survived out of sheer stubbornness). But had a VERY Western flavor to it, a lot like Deadlands in that regard. Anyway, my major point was that it had a class dedicated to being able to summon dust-devils/tornandos and lasso them, then ride them. I am sure you can figure out which hero this is based on...

A keyword to help you find said thread might be "white-light shakes" although it might be a space or nothing at all instead of a hyphen.
