Good map! I completed it playing as the Orc faction in 5 months. I can say that I was incredibly lucky in one of the key battles, when defending against a Necromancer with a horde of ghosts – my hoofed creatures hit three times out of four. This basically decided the outcome. Then came a series of intense battles, including taking three Necropolis castles with all their skeletons and archers, and later, the Blood Claw.
I would add that it would be good to clear out the artifacts scattered on the map later on, and, of course, the shop with them, which is located four days from the capital. Instead, I would suggest adding a couple of huts for quests.
And yes... the Crown of Sar-Iss is definitely an overpowered item for the Dark Elves, but it's completely useless for the Orcs.
To be honest, I tried several times, but I couldn't complete the map playing as the Empire (my favorite faction). Maybe Vittorio would have had a chance, but he was busy at the beginning.
In any case, the map is engaging because of its difficulty, and I thank the author for that!
Wishing you creative success!
P.S. I was amused by the player who captured a Necropolis by the end of the first week, even though it takes four days to get there without stopping. But raising the Mage's attack and defense first...))
