The resource spawn was good, with plenty of wood and ore, so I immediately built a Fortress in the second castle. I placed one archer garrison. I built up archers and pegasi in both castles. I didn't get a single hero during the war, and until the end of the game, I only had mages. On day 141, an opponent attacked with 26 ducks and 136 upgraded elves. With luck and happiness, they defeated me in the first round. The opponent didn't surrender; they recruited 50 upgraded dwarves and attacked his castle, where a hero with 300 mana and Armageddon was waiting, but without any troops.
Thank you for the game.
