I previously wrote that I completed almost all missions slowly to get the most out of them. Here, I was a little dishonest. I always try to destroy the main enemy forces as quickly as possible, and then slowly and tediously level up the hero and collect all the bonuses. In this mission, the main thing is to curse at least one city as quickly as possible. It immediately becomes easier.
