Because the opponent focused on strengthening their own forces and neglected to suppress me, although I started weak, after building a level 4 guild with the Resurrection spell, I only needed to build one Dragon Tower to obtain the Earth Book and the Mage's Hat. I then explored the map, gathering resources, and while the opponent was out searching for the Movement spell, I seized their cities. Within a week, I built Phoenixes and Archangels, and eventually obtained high stats and the Holy Grail, making my military strength comparable to the opponent's.
Finally, the opponent had no cities and tried to retreat, but I attacked proactively, engaging in a bloodbath with a red-ball spell and a strong blood-focused lineup. Because I had many archers and a speed bonus of +2, I maintained the advantage on the battlefield, and they were defeated.
In this game, if the opponent had obtained Jump, Fly, or Recall spells earlier, it would have been a disadvantage for me.
Thanks for the good game.
