Ah! Well how was it that the rune circle changed from white to black and then eventually to red? It just seems like to be some sort of fusion of Team RWBY's power, so I'm guessing that Weiss found a way combine the power of her Myrtenaster with Blake's (and possibly Ruby's) aura? Bear in mind she looked drained after she summoned those rune circles up the face of the cliff to help Ruby finish off the Nevermore... so there maybe some use of aura involved.

So I still believe that maybe (I say MAYBE) there is a way for Hunters and Huntresses to combine their auras in order to take down large threats like the Nevermore or the Deathstalker... or something even bigger.
