> summon shield
Your shield lasts just long enough to protect you from Grue Slayer's light-modded laser cannon powered by his own awesome sarcasm, which is a hell of a lot better than your own. You are stunned for 1 turn. Grue Slayer, however, wastes 2 turns gloating about the +1 kill count he just got, which allows you to switch to your cannon's laser mod. Your move!
