She's proven her theory at least- the shields are strong as hell, but only work with harmful magic it seems. She looks toward the prism, and after picking up a nearby stone, darts off into the air...flying as high as she possibly can.

She doesn't move over the prism yet however. Instead...she traces a line with her eye, and with a deep breath summons a wall of Dark Signer Flame below. She doesn't expect it to harm the other of course.

But it'll certainly catch their eye, and with any luck lure those nearest the prism away enough for her to act.
