Nie Huaisang looks through the book, and yes, the spells are closer to the one he (they?) need, but it isn't quite what he had in mind. He sets the book down and picks up a scroll, not minding one big that Yalun's gotten closer to him.

"This might have it. Have you ever drawn an array before? We'll have to craft one. We'll need cinnabar, probably, incense..." He unfurls the last bit of the scroll and smiles at the illustration he sees - two men, one in the process of turning into the other. "This must be it."
