Subjective: The following part of this article is subjective to the editor's writing. Therefore, it may not work for everyone.

The Wyvern Riders that appear as reinforcements will head directly into the town. It's best to use a strong flying unit to prevent them from landing inside the town's borders so that the villagers don't complain and give you less of a reward. Alternately, have a couple archers stand in the bottom right part of the city to eliminate the flyers that get in.

The Wyvern Riders are quite strong for the recommended level, entirely capable of avoiding doubles and surviving hits from bows. Rallies from units like Ignatz (Speed), Raphael and Annette (Strength) can help immensely.
