Magic B6C14

A barrier in the middle of their fight and Cinder's. There was no telling how thick it would be, but it couldn't be so thick that Cinder herself was at risk. Maybe a foot or two at most. The problem was that the thickness didn't matter so much as the intensity. No one was going to die by running out of oxygen here; they were going to be burned to death.

It was the temperature that was the real problem, and if the flames were self-sustaining, or being sustained from Phoenix, then Weiss alone wouldn't be able to affect that. Maybe she would if she had a Mage Array with loads of others chiming in to help, but there was no way we could get something like that set up around here.
