thx for game
On day 121, I checked again - there were three units, but even with such a powerful hero, I couldn't take them. I spent another four days wandering around, captured a mini-Hive, bought more troops, and barely managed to win on day 125. The entrances to the treasure rooms were very conveniently located near the road - I went to the first one, where there were two Conservatories and two Hives. I spent a lot of time there, only clearing it by day 136, and then I went to the second one - one Hive and a useless Utopia. I cleared it by day 147. I also went to the third one - I immediately found a Utopia there, spent only three days, and got a +5 sword. Conclusion: treasure rooms are a pain, and it's not worth going there on foot.
The roads weren't much better - one exit from the square took three days to reach, and the second one led to a one-way path, where I wasted two days. I randomly acquired some good skills - in the end, Tazara got either Wisdom or Earth.
The roads and one-way paths made everything take much longer, so I decided to attack the opponent's main castle. And that's exactly what happened.
By the time I attacked, the opponent had only taken one Consul unit out of the three native ones, but then he simply built Angels in his castle, teleported them to the Grand Magus, and calmly gathered four Utopias to control the map and improve his stats without even leaving his square.
You're welcome.
