Sphynx sets to work. He makes a catalog of required components, clears an area of the room, if necessary, and begins laying out components at hand, leaving notes to mark what is missing. He conveys to those remaining in the room what components are missing, in case some can be found about the building. Lastly, taking very special parchment, ink, and quill, he begins inscribing the spell, paying particular attention to the necessary re-wording.
