I am under the impression that Dust and Aura are not linked, where you need one for the other. Weiss in the series for example seems to be able to use Dust very effectively, but so far has not shown any kind of Aura related skills or been said to have any. However someone noted that she appeared tired after using a large amount of Dust-attacks to help defeat the Nevermore. Some believe this was because she was using her Aura, thinking Aura is like a trigger for Dust, but I have a different idea.

When Weiss is yelling at Ruby for knocking over her suit cases, Ruby sneezes and it explodes. First off, this shows that Aura isn't exactly required to activate Dust. Then when Weiss is talking about Dust properties, she mentions that Dust is energy. From this, I believe that a person can control Dust using their own energy, separate from Aura. Both Aura and Dust may be required for someone to use them, but obviously it requires more energy for stronger skills. This would explain why Weiss was tired after the Nevermore attack, as she poured a large amount of her energy into that series of attacks.
