On the first day, with three heroes, I couldn't even buy a basic unit, but I bought a mercenary and all the heroes were on fake accounts. I took a wood hut and a couple of sawmills, built them up, and also built an elf hut. On turn 113, I saw another elf hut, so we continued playing. I kept trying to find a passage, but everywhere there were guards. There were three guards in different locations. I broke through to the swamp, built a tavern there, and also built a unicorn stable and a castle. On the second day, I was going to go to the Dungeon, but the secondary hero found a passage to the Necropolis territory. From there, he went to the opponent, who scouted me and holed up in a stronghold with 40 storm units. The hero was strong, but I managed to break through. Kir was 8 8 2 3 (expert in earth magic and advanced attack +1 speed) and 50 great elves shot at everything; the unicorns didn't participate in the battle. Ivor was also an expert in earth magic with powerful stats and a lot of air units, but Kir got lucky.
Thanks for the game.
