The hero took an intelligence expert, a helmet for +2 knowledge, and doubled his mana. In his home castle, he built a level 2 structure. He cleared a path to the opponent's side (with 90 griffins) and won.
Thanks for the game!

I confirm that there was no road to the second level, and the path was rough. He was slowed down significantly due to the penalty, but overall, it was a very good game. However, the opponent arrived too early and with a bolt... Without the bolt, I probably would have killed him in the castle with a wave of death, especially since there wasn't much of an army there (although I didn't have much either), but the bolt with 120 damage forced me to retreat halfway through. After that, it was impossible to win, so I didn't drag it out.

Thanks for the game!
