From the character template/rules post...
Infusion: Infusion is the archaic and highly dangerous system of utilizing Dust in combat. One can infuse Dust with their clothing, or even directly to their skin in order to gain the benefits of it. This is a wildly dangerous and painful practice that, while not outlawed, is very rarely practiced. The advent of technology has allowed for safer applications of Dust in combat while maintaining the same firepower, or in many cases increasing it. As such, the benefits of infusion do not outweigh the disadvantages. Infused dust is known to spontaneously combust if hit without aura shielding, inflicting significant damage or death to the person wearing it. Infusion also does not grant abilities/attacks that technology cannot already create.
If your character infuses Dust, you need to very clearly explain why they do it, why they don't use technology(which is safer and more powerful) and how they are still alive.
We also have passive variants of infusions call "Glamour." Glamour can be infused into clothing to create passive effects ranging from using fire dust to keep clothing warm in cold weather or using ice dust to keep cool in the summer to using dust in clothing to create a sparkling fashion effect.
Glamour is somewhat pricey and must be replenished though, so keep that in mind when making a character.
