On day 1, I managed to capture a Giant stronghold. With it, the development went quickly. I also captured 2 Naga strongholds up to level 117. I reached level 122 by leveling up Solmyr in magic. And then I faced an unpleasant surprise. The roads were buggy, so the path immediately led to the Barbarian spawn. I had to trudge through the desert, hoping to reach the castle before Crag. I didn't make it. In the tavern, I found Ignissa, level 30, and transferred all my troops to her. But it didn't help. The opponent probably only reached level 126, but I didn't manage to take anything, essentially, except for a few taverns with not very good heroes.
Thank you for the game!
