The Activity Club and the Ice Dungeon Challenge

Ed jumps to the side, but he's just a touch too slow to completely get out of the way. The ball of light glances off his shoulder, which knocks him off balance and onto his back in the snow. He's not sure where the fairy is now, but he's definitely a sitting target. He has two ways to get back into the fight. He can either get up quickly and move, which would risk a sneak attack from the fairy, or he can draw a shield to ready himself for the fight, which is slow and would risk him being found before he can get up.

Which should he do?
