She leaves behind a clone filled with fire that explodes in Roman's face in No Brakes. She also leaves behind an ice clone and an earth clone, as well as one that dissipates into inky darkness, which is unlike any other clone she has used before or after that fight. Just before the fight Weiss gave her a magazine clip for Gambol Shroud with various dusts in it, and when she creates the elemental clones you can hear her gun being fired in the background.

I thinnk it's pretty evident that her semblance can be used with dust. It doesn't need dust to make the standard 'shell' clones, but she can mix it with dust to make elemental clones.
