Don't make me laugh. If I was fighting Spook all alone in an arena or something, he wouldn't last very long. Again, I have the bands of mourning and he only was only a tineye at the time.
Then again, if there were people around that I cared about and he came up with a convoluted threat off the top of his head, I'd have no choice but to toss the bands out the window and try to sit on him. Spook wasn't much of a fighter during book 2, so I think I'd have a pretty good chance of catching him and pinning him down. If he ran away, I guess I'd need to settle for a draw.
