The dust devil spell creates an elemental force resembling a dust devil that picks up stuff as it moves:
As a bonus action, you can move the dust devil up to 30 feet in any direction. If the dust devil moves over sand, dust, loose dirt, or small gravel, it sucks up the material and forms a 10-foot-radius cloud of debris around itself that lasts until the start of your next turn. The cloud heavily obscures its area.
I had the idea to pick up some sawdust from a lumberyard, soak it in alcohol, let the dust devil pick it up, then set it alight to create a flaming burning dust devil.
Would this be possible to do with the dust devil spell?
