"You mean tempering?" Gravis asked. "You don't need tempering."
"No, I don't," Arc said, "but I want to. I haven't fought someone in billions of years. I almost forgot what it feels like. The thrill of feeling one's death to be only a single mistake away. I haven't had this feeling since I went through my specialized will tempering."
