I'm going to go out on a limb and say: no, you can't gather Aura into balls and throw them; that's what Dust is for.

Not going to say anything else said so far is wrong (though I would personally assume it's Aura shaping Dust, not the other way around), but it looks to me like Aura is inwardly oriented: it shields yourself; enhances yourself; it heals yourself; it let's you sense enemies around yourself.

Dust, if I'm understanding correctly, is outwardly oriented: it makes fire, storm clouds, etc. and presumably powers most of the technology of this world (including, I assume, the "robots" in the black trailer). Of course, maybe "Dust" is just energy in physical form, and Aura can shape it into "magic" (weapons probably make it easier focus both Aura and Dust in battle - you know, to strike harder/sharper, direct flame, etc.).
