On 121-2, I traded almost full, bought Air Elementals and 4 own units from the Citadel, and went back to fighting off the AI, since my army had nothing else to do and all the good stuff was mostly in the swamp. Found boots. By the end of the week, I killed another 2 AI players; took a couple of max Medusa zones, birds were in the Citadel at home, while the AI had a bird config in the Castle. By 131, things started moving with the birds - fought for a Town Portal scroll, built up the Tower, and by the end of the week, got wings and hives from a super treasure zone. I broke through 3 first Dragon Utopias in a chain - they gave decent stats. By 143, I had already taken 7+ Dragon Utopias, cleared the swamp treasure zone with wings; there was still no Dimension Door, but everything else was there - Alliance, handcuffs, red orb, 100+ Monarchs, etc.
On 211, I finally got a Dimension Door in the 3rd Tower, and finishing it off was easy - 4 heroes with 3200+ moves and Dimension Door, 115 Monarchs, 20+ birds, stats around 40. Thanks for the game.
The hardest battles are fought in the mind
