User blog comment:VedranTheII/Pretentious Diaries 2: What tricks would you teach your Aura?/@comment-5217560-20150719083609/@comment-24993958-20150719093116

About Dust: Do you remember where you heard that? I can’t seem to find any place that states elemental attacks are doable without dust.

About Tricks: I don’t think it’s impossible to use aura to heal others…but I don’t think it’s universal. If I had to guess…and I can only guess for now, aura is a bit like blood, so it might have different types, and as such trying to transfer aura between two people with a different type can’t work, due to incompatibility. My solution to that was to make a semblance that specifically allowed someone to change their aura into another’s, essentially allowing him to pull off what you’re describing…still going back to the blood analogy it might be possible for there to be a type of aura that can act as a universal donor…I guess in the end Jaune will probably answer this question, given his reserves and his nice guy nature that might push him to try that at some point.
