I used dwellings 1, 2, and 7. The starting town had regeneration, which made the task easier, but even with regeneration, I constantly suffered losses. I can't seem to win without using this strategy. I didn't make it to the mentor because I saw that my opponent was trying to reach me from the center. The portal was near my town and hadn't been broken yet, so I teleported back to my town from the treasure. That's what happened that day. My opponent broke the portal, but couldn't reach my town, which allowed me to outsmart him twice with a level 18 Leto with Chaos magic. I took out half of his archers, and so on. My opponent had about 40 knights, but I was in my town, and they couldn't do anything. After the final battle started, after a few turns, my opponent surrendered. Thanks for the game.
