121 with two hydras took a Dragon Fly Hive of 8 wyverns (auto-combat couldn't do it anymore, had to play manually), then the external dwelling, and played on, constantly losing wyverns. For some reason there were very few gold-producing buildings, and I didn't see a single Griffin Conservatory the whole game.
At the end of the third week, the opponent was showing archangels, so on day 141 I hastily started collecting Dragon Utopias. Managed to take four; I got a sword +all, shield +all, hourglass, cap, wings, titan's cuirass, black orb. Finishing week 144, I knew I was in the opponent's line of sight, so I equipped the cuirass, cap, and black orb to at least implode to my heart's content, but I was attacked by 16 archangels — they were immediately blocked by anti-magic, the opponent threatened shackles, and I started summoning imps. My biggest stack — 9 hydras — was almost completely wiped out by a single hit from the archangels. The opponent could have won the fight without any trouble; he just needed to force me to waste my mana early. But he caught me with one stack of earth elementals, cast Blind, then spent all his mana on Implosion and Armageddon, and with only 4 mana left, dealt a devastating but not fatal blow. In short, I won the fight on earth elementals, and both heroes ended up in the tavern. I had several times more gold, so I also dug up my hero faster. At that point, the blue player surrendered.
Thanks for the game!
