Heat aura

I had never lowered the shield, and my actions had been obscured by all the fire chewing away at it—so Ascher recognized the danger a second too late, and that was where her inexperience showed. She might have real power and a gift with fire, but in a fight there’s no time to think your way through spells and counterspells. Either you’ve done your homework or you haven’t, and despite the advantage of having Lasciel in her corner, Ascher wasn’t ready for something like this. She was focused entirely on offense, not on protecting herself as well, and couldn’t come up with a counter in time.
The wall hit her with about the same force as an oncoming garbage truck, and blew her right out of the veil of purple mist that clung to her naked form. She flew back off the stage in a windmill of flailing limbs, and crashed into a display of particularly fine ecclesiastical robes and garments, most of which burst into flame as the sheath of shimmering heat around her body brushed against them.
