3 Dragon Utopias (only for stats, +2 Books of Water and Fire), Hives with 50 birds, and that's it.
The 2nd treasure zone gave KS + AODT + all the Earth.
At 137, I upgraded 80 birds and 1,200 bones. At 141, I broke into the center treasure zone, and a couple of days later, the main opponent appeared. Then a few more Hives at home, and I attacked him in a Castle. The Miner had stats twice as high, 10 Archers, 50 birds, but 1,400 bones with 9 HP carried the match.
Thanks for the game!
