The Secret Triwizard Challenge

You sprint as fast as you can to the exit. The spider notices you and starts making its way towards you, though each step is painstakingly slow.
You're a little over halfway through the clearing when your foot gets caught, and you fall, hard. You look at your foot and find that it's trapped in a large mound of spiderweb. You pull on your leg, but the spiderweb is sticking well to your foot.
The spider is closer than you'd like it to be, even if it is cursed with the Jelly Legs Jinx. Do you focus on your foot or the spider first?
