In the first week, I focused on secondary skills, leveling up in my home castle (1-6) and building a stronghold. In the second week, I got dragons and angels, joined the 5th guild, learned Implosion, and acquired several Pandora boxes for experience and magic. In the third week, I got two Utopias with artifacts. In the fourth week, I got another secondary skill, and due to my good stats and army, my opponent surrendered.
Thank you for the game.
