The Secret Triwizard Challenge

"Diffindo!" you yell. Your charm is too powerful, and you end up nearly cutting your foot off.
The spider is too close, you're in so much pain, and you're bleeding out. A broom monitor swoops down, lifts you into the air, and flies as fast as they can to the Hospital Wing.
Great job, nincompoop. You just lost the race! YOU LOSE!
