The Activity Club and the Ice Dungeon Challenge

Ed is standing in a terrain covered in snow that reaches his ankles. There are snowmen and mounds of snow scattered haphazardly around the space.

The fairy girl is smaller than him, but as he watches, she turns into a floating ball of light slightly larger than Ed's fist. Her glow bounces of the snow, blinding him for a moment. In this time, she hurls herself at him, and when Ed realizes what is happening, he only has a few seconds to react.

What should he do?
