After using all the restarts, Gurnisson without a ballista appeared, so Gretchin became the main hero. The respawn point was good, there was a lot of money, and in the first week, there were monsters in the castle + a native secondary unit. In the second week, there was a third native castle and a monster and bird recruitment building, so the army was large. I was looking for a powerful item - I only found one Utopia (book of air, mage hat, shield +4 to everything). I broke through the Guardian Order (a horde of unicorns and many ancient monsters), and took an empty castle from the opponent. We played for another week, and the opponent surrendered - the Final Battle never happened. I analyzed the save file: due to having three identical castles, I had a colossal advantage in the army, I had almost all the magic, and I was slightly behind in stats.
Thank you for the game.
