User blog comment:WeissSchnee/A Question About Dust Usage/@comment-24828824-20151128124932

This is exactly why it has been judged "Awaiting Canon Info" so far. We just dont know enough about how Dust is used. We see Weiss coat her blade with it for some effects (like setting it on fire and throwing a blast of it at enemies with a swing) but we also see her create entire ice sculptures and even animate some of those (the giant fist grabbing the two ABRN guys, the ice sword being thrown around during The Breach, arguably Winter's ice nevermores) and we have no clue as to how that is suposed to work.

Then there is the issue with how someone infuses an object or a body with Dust, we have not seen how that works either. we have not seen how Cinder made her ionfiltrator suit with the dust weapons and we have no examples of actual peoplke with infused bodies. maybe it is as simple as cutting open your chest and placing a crystal in your body before sowing it back up, maybe you need to inhale Dust and survive the reaction, maybe it requires a whole ritual, we just dont know. Hell we're lucky that Dust Infused clothing is allowed as we also know pextremely little about those.

Now if yuou really just want it to be just a cannister with a few selectable types of Dust that can be utilized by the user just have it be built into a chest piece or a backpack, you can create the same look that way. if you want to infuse someone with different types of dust depending on the situation you'll just have to wait until we know more about it. for all we know you can only do it with one type and it is permanent.
