The Secret Triwizard Challenge
The spider is the most urgent matter since it's actively trying to kill you. The fire will have to wait.
You turn to the spider, still slowly making its way towards you on its wobbly legs. You shout, "Stupefy!" and hit the spider's front legs.
The spider falls hard, and because of the Jelly Legs Jinx, it's unable to get back up. You put out the fire with Aguamenti and nearly slip in the mud it makes (man, can you imagine how bad it would be if you slipped BEFORE the spider was taken out? You'd probably have died or lost the race or something. Good thing you didn't choose that!). You walk through the exit, ready to continue this race.
