Demon invasion.

Jaliba managed to win despite having ten times fewer troops . He was very lucky that he didn't have gargoyles, and he was casting random spells, considering he had antimagic, with which he could have easily countered my berserker. And Sandro's cloak, obtained from one of the mages, is very helpful.

To fight effectively, a battle to the last is essential.
Berserkers are good, but they need to be built up, and resources are scarce. So, you can skip the Dark faction at the beginning and focus on building a 3rd-level ballista, fire arrows, a tent, and burn with hellfire and chain lightning, and then move on.

BDP is definitely one of the most important perks in this campaign. But without the Dark faction, it's hard to know how to play, because without mass dispel, the archers simply destroy everything. And you can't defeat gargoyles, golems, and djinn with chain lightning and hellfire.

For some reason, the Necropolis faction doesn't want to attack me in the Castle. One of them even has fewer troops than Jaliba. I could have defeated them in the same way, even easier, because they don't have any artifacts for initiative or a magic mirror.

Now, one of them has given his army to the other, but even with that army, he sailed away on a ship instead of finishing me off. So, I'm getting monthly reinforcements from the dwellings. Now I'll gather resources for the 5th-level mage guild for a city portal and try a raid.

The raid wasn't very successful. I only managed to clear the lower level of the dungeon, get an upgrade, and get the Dwellings of Horses. Then Faiz arrived with a bunch of titans, but he was defeated on the first try, although with some losses. He was probably the last hero of the Mages, and after him, Waishan appeared with fifty titans and an earthquake spell that kills 50 dogs. And on the horizon, there are two more Yellow heroes, a knight and a dwarf. Well, in principle, you can fight even with large armies if you don't have artifacts for initiative...

I decided to reload and try the raid again, and this time it was very successful. I went to the surface in the center, took a quest from the sphinx, cleared the first pyramid, then a hundred and fifty cyclops nearby, and got the Amulet of the Blood Claw. A Necropolis hero appeared on the right, so I started running to the left, overtaking him by finding a path. Along the way, I captured two mines, reached the second pyramid, got a mask there, a mentor was on one side, and the Staff of the Underworld was on the other side with decent guards, but the Necropolis hero was right behind me, so I went straight to Utopia, cleared it, and teleported to the Castle. During the raid, I got a lot of dragon artifacts and the Greaves of the King of Dwarves, and this time Faiz was defeated without a chance, with only imps taking losses (his gremlins moved before everyone else in any case + a couple of lightning bolts from the titans).

I also defeated Waishan, who came after him. The losses were significant due to magic, but I saved almost all the demons and horses. I got some reinforcements, restored the dogs more or less, the Yellow hero is nowhere to be seen, a dwarf with twenty titans and good magic appears in the tavern, but after the battle with Waishan, I have almost a full set of the King of Dwarves, so it will be easier against magic. And another hero joined the Necropolis, so now he has legions, up to a hundred dragons. But since the area behind the garrison is probably safe from the Necropolis, I can fight in raids without problems and increase my strength. The Yellow hero will only become weaker without heroes and magic. Without artifacts for initiative, their army is not very strong
