Cheating AIG 5

This one can be annoying, since it's luck based. Easiest way to get it is to create a new character, preferably a Sorcerer since they have the least health points (30). Start up a quick battle game on Hard difficulty, and hope you get taken out first turn. I don't think it matters which enemy (Rats or Goblin). If you don't die right away, hit the back button, quit and retry. Some people have been lucky enough to get this quite quickly, while it took me a few hours. It seems like results are better on the larger board since there are a lot more 4x combos to keep them going, but there's no way to choose that board before you start, so again it comes down to luck.
