For me, the main difficulty was dealing with the elementals. I also defeated them using upgraded golems, but I had to replay the battle many times because it wasn't easy to win with that composition, and at best, I was left with 2 imps, which would clearly make it difficult to defeat the enemies. I lost one while waiting for the green hero in the city to attack me, because it was impossible to defeat him in the open field. The idea of playing with two heroes also failed because I wanted to use a fire-ball hero to stay in the yellow player's city and win the siege, but the yellow player was waiting for me on the shore with open arms, and as a result, I weakened his army a lot, and then Deleb came and easily finished him off. I didn't replay it because I had already sent this map to hell several times after failing with the water elementals, and after cooling down, I returned to the walkthrough. And also, my name is "inattentiveness," because I forgot to exchange resources for ore, but I hope that the results will not be so close that it will affect the ranking.
And I almost forgot, the result was 19 days.
