Nightmarish roads (more precisely, one road that becomes a one-way street, and before it there’s a block of 27 upgraded Gorgons). In the beginning of week 4, I only had one castle (my home castle) and Kir with mega-upgrades (water, ballistics; earth eventually came into play on level 14, and air – on level 21 – by the finale), without stables and movement artifacts. But I managed to get 3 Dragon Utopias + 15 all stats and a cap on level 5. I took over the main opponent's castle nearby, and on the next turn, I encountered an army at the location. 1:0.
Thanks for the game!
