This level wasn't nearly as hard, but maybe that's because I sort of knew what to expect. While the rest of my units stayed in the safe zone at the bottom of the map, Fredrick and Stahl (why didn't I choose Chrom? Pfft, idk) went to the center of the map and waited to be attacked. They killed all the things. However, the "safe-zone" wasn't as safe as I had hoped. By the time the bottom of the map was clear, my only untis left were Alexandra (avatar), Chrom, Fredrick, and Stahl. Fortunately, I was still able to clear the map with a good combination of strength, skill, and all around awesomeness.
