I took a restart (dwellings 2,3 and none of the four Inferno heroes caught the war machines), we played the second map. Dwellings 2,5. The starting zone is a huge sausage, I only saw dwellings on day 5. But I bought two Necropolis units and Marbas leveled up well. Standardly, I attacked the 122 center with Ghosts, the guards - wow, almost died (Yarls + blade dancers that are white + 130 Master Spearmen, who pulled the old ladies out of the corner, freaks). I started attacking there, but didn't find it right away, on the 4th portal. I didn't stay in the third zone for long, since my distance to the main object was 3.5 hero moves, so I decided to break through from the third zone to another center and from there look for a portal to the adjacent zone to Exe. Very lucky that this portal was the very first one. On 144 I captured the Castle. We ran around for a few moves, Exe couldn't reach the Castle quickly and surrendered. Thanks for the game.
P.S. I think my crooked Marbas with stats 17 19 didn't have much chance against Wing 27 29... Just lucky. It happens.
