At first, I took two restarts, I don't remember why (maybe I didn't like the races). The first time (before the restarts), by the way, each of the Stronghold Elves had a victory). I didn't take Vis as a restart, so I defeated the Dark Elves with the High Elves.
I played with the hero Talannar, Vis was Iranne. I initially wanted to level up in the same way as in the game with Arca (i.e., take a Stronghold), but that's difficult, ideally, the Stronghold would be at level 25. I finished the game on the second try. And as I built the guild, I noticed that there was poor Light magic and good Chaos magic. I abandoned the basics of Light and switched to Chaos. I bought Sar-Issa's robe +6 to spell power, and before the battle with Vis, I upgraded the druids to blue, which also give a bonus. But that was the second battle, because we had met earlier on the map.
Vis quickly captured a hundred cities all over the map, and as soon as I emerged on the surface and captured one, Vis appeared out of nowhere. I attacked him, killed the dragons, and ran away. I surrendered, or rather, I saved the druids, because I really needed them. Because it was hot there.
After a while, Vis came to my city. But I was no longer that newbie with forty druids, which made up the main army; I bought 11 dragons and a lot of other things in the city. Vis also got stronger, of course, but his armies were much weaker than mine. But he cast spells fiercely, which is the main danger of the Dark Elves. I did destroy his catapult after its first shot, but soon I came out of the walls myself, because he showered me with spells. In short, I left him with one witch, and he left me with the ents (there were many left), unicorns, and all the druids.
I immediately went to the city that I had owned for a short time. And there, to my surprise, Iranne was sitting with a squad of archers. There were ten elves there. But Vis wisely killed me while all the elves were invisible; he showered me with his house spell. He also summoned a phoenix, which caused a lot of trouble. And I somehow managed to break through the castle walls and went there with ents and unicorns to find the sneaky invisibles. I also cast spells with the hero. Oh, it's a pity that I didn't have a meteor shower spell; I would have quickly defeated them all. But I only had a wall of fire and stone spikes. While I was killing them all, Vis and the phoenix ate my horde of druids (fortunately, I had divided it before the battle; I foolishly hoped that they would go first and defeat the archers one by one). In the end, I completely messed up; Vis had one archer left, who had even revealed himself (came out of invisibility). And I somehow messed up and forgot about him. As a result, instead of killing him with the hero, I put up a wall of fire, and the phoenix ate my fifteen unicorns. I survived with 16 wild ents.
But I killed the hero and took a lot of artifacts. Then I went to invade his other castles, and after a while, Vis got tired of it and surrendered.
P.S., to Vis's post. I said that yes, I would attack, and I did attack. I just didn't click on the right chest (well, damn, we had a very long break after that, I even forgot how I got to you then). Well, I attacked on the next turn, what's the big deal?
And about the fact that I clicked on the wrong one, there's really no excuse; you wouldn't have destroyed 16 ents with a phoenix and an enhanced earth shock.
