Scrapes water

She held up a small spray can. “How am I supposed to lay out a circle on the floor when there’s a layer of water over it? Did you think about that?”
“Deirdre,” Nicodemus said.
Deirdre promptly swarmed halfway down the stairs, and then there were several sharp sounds of impact, as her metallic hair shot out, surrounding Ascher, and slammed onto the floor around her. The flat ribbonlike hairs spread out, edge down, scraping along the marble tile like a squeegee, sweeping the standing water away.
Ascher looked like she nearly had a heart attack when Deirdre did that, and cast a glare up at the Denarian. But then she took the can and sprayed a layer of what looked like some kind of aerosolized plastic or rubber onto the floor. She laid it out in a large circle around her, overlapping the circle onto the wall and continuing it up to a few inches above her head. It was lopsided, but technically a circle didn’t have to be a perfect one to contain the magic. It was just a lot more efficient—not to mention professional—that way.
Ascher, who was looking damned appealing in her wet clothes (and dammit, how could I blame my reaction on the Winter mantle when it was being held at bay by iron?), went over the circle again, making sure the plastic spray was especially thick at the joints of the floor and wall. Then she nodded once, bent, and twisted her wrist so that a couple of drops of her blood fell from the manacles onto the circle. It snapped up into place at once, a screen of invisible energy, and she promptly unlocked her manacles and dropped them onto the floor at her feet. Then she narrowed her eyes, touched her finger to the wall inside the circle, and murmured a quiet word.
