That's a nice way to look at it, with the body having to compensate for this new energy expelling out by needing more energy in. I feel like using another Dust crystal would have the effect of an energy drink however, gives the body a boost but too much and too often could lead to bodily harm and even fatal effects. Perhaps not even a full crystal but small doses. Or maybe instead of a short term boost it's a long term addition if done in small doses. Like slowly letting the body adjust to more and more so it can handle longer and more powerful expulsions of energy. The other Dust thing I wonder about is when it's fused in clothing. I believe the only time we see this is with Vol. 2 Cinder with her infiltration scene, though I'm not exactly sure what. The other time was WoR Dust where there was the silhouette of the man with a scarf that was turning into flames or something. Does Dust clothing have properties of both materials and can switch? How does a person control that? This seems to be the most lacking in detail and anything made with this is left to creator's freedom and imagination with fan works. I've tried thinking of a fire and ice bandages that my OC wears around their arms. In combat they act like whips of sorts: one of fire and the other a flexible blade of ice.
