I build a stable, buy troops, and head to take the second Castle. On day 112, I take the Castle, go to attack the bug, but some reinforcements were delayed, and in the end, I only managed to reach day 114. On day 114, I couldn't place any champions (I bought crusaders and something else). So, they were only placed on day 115. I played with champions because they are very quick to place, and my strategy revolved around them. I take a strategic point with the help of two champions. It seems I broke the gold mine towards the end of the week, although I only took it on day 8. I took it with 3 champions, 6 crusaders, and 4 pikemen. I gather 8 champions from the Castle and the strategic point, and run to take the third Castle (in the meantime, I also got snowshoes). On day 126, I arrived at the Castle, but I was afraid to take it immediately with 8 champions. I leveled up my heroes (the main thing is tactics, reaching 3240), brought 3 more champions and 39 archers (to take out the necromancer, but they weren't really needed). With a little help, on day 132, I took the third Castle without any losses. I go to level up. Among the artifacts, I had the Book of Order and the Doom Armor, but the book was found after 2 kings. I go to level up and gather money. I brought magic up to the 4th level (1 Order and 1 Life), also hired a Lord and a Lifemage, and placed more champions in the second Castle. With 15 champions, I take the book, and with the help of teleport, I start quickly jumping between Castles and teaching the Lifemage spells.
Taking 23 champions and a dragon (I ran without them before because I was short on money :D), I go to attack the portal at the end of the 4th week (it could have been done much earlier; all you need is a berserker and slow).
I clear my side with the loss of 1 champion. I teleport to the middle Castle, restore mana and a champion (I didn't bring in 5 more). I take the middle, especially the compendium for all 4 levels of magic (it's the most important for the main Lifemage). The second guard of the portal is taken without losses. On the next turn, I take the opponent's secondary Castle, and there are 2 more phoenixes. I buy them and move on. Then, Snaiper appears, brings in all available troops, and attacks my powerful army. In general, he had no chance in a frontal battle; in the end, I only lost 1 phoenix. But he still held out well, especially since it was his first time playing on this map. :smile20: Thanks for the game!
P.S. Somewhere after capturing the 3rd Castle, I completely slowed down due to relaxation and not wanting to rush :( I'm lazy :(
Here, Snaiper, are the saves. The pace is average (even slow towards the end), but it's good for learning the map :) http://slil.ru/27775082

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
