The Activity Club and the Ice Dungeon Challenge

Isabel shoots a spec shot at the back of the man's head. He stumbles forward, and when he turns around to face her, Isabel has already shot a second time. He gets a face full of spec shot, and he falls to his knees, rubbing his eyes. Isabel shoots a third spec shot, finally blasting the man onto his back, stunned. Isabel snaps the candy cane tree she is on, and she falls with the tree onto the man. It looks very cool and dramatic.

It's time for Isabel to end this. What should she do?
