Route in brief: High Elves(1-2-6), Scorpicors(1-3-4), Behemoths and Elementals(earth) (1-3-6), D.Behemoths(1-4-1), Minotaurs(1-4-3), Hydras and hut(south-east)(1-4-4), Hydras and hut2(north-east)(1-4-5), Giants+2 trees(1-4-6).

Why did it take so long underground? I got High Elves at 1:1:6. But afterwards, since the army was weak and the hero wasn't leveled up, I took my main hero southeast to the fortress of life (there's a stable there). Then, like you, I went for the Scorpicors through the light blue gates (a helper hero opened the tent in area 1)

1 - 2
4 - 3 Here is the map scheme - divided into 4 areas.

area N3:
Earth Elementals by the gold mine (meanwhile, another helper hero opened the yellow tent - harpies were passed along a chain between him and the main hero). Then Behemoths, but by that time I had about 120 summoned harpies and had collected the Cursed Armor artifact (the fight was tough - little mana and no Spirit of Despair, but the Snake helped). I should mention that you must not forget to pick up the wizard's cloak right there. One of the helpers somewhere snagged a magic collar from the AI in area 1 near the fortress of life, I think Alexandretta.

From here, my route diverges from yours. I transferred the harpies back across the sea to area N2, while the main hero fled there.
So, area N2:
And there I got lucky and refilled double mana because I was completely dry, and an enemy hero happened to be near that fortress. The main hero with harpies(150 qty) + Snake fled for money to the fortress of life in the southeast. The helper finished off the hero I fled from and, lo and behold - he had the third piece of the Wizard's Ring artifact (spell duration +50) and the Spirit of Despair!!! This hero was immediately transferred to Alexandretta. And the main hero now has a second assembled artifact. He also has Clone, Blind, Slow, and Blessing magic - this is enough to take down slow stompers, as Kyle calls them :)

Now for the Hydrants+hut with a +50000 bonus. Then the harpies are passed along a chain to the Central fortress of this area. The main hero flees there. Then Giants + tree, we move on our own to hit the Devils' fortress (we start preparing the portal gate there) and kill the Gorgon Legion there. We leave the harpies in the fortress. And we slip away into area N1. Partisans were active there, whose main force was summoned Vamps. They captured the fortress near the hut with the quest from the Gorgons. We visit the hut +50000. Was it unguarded? Why - I don't know. And now I flee to area N3. Partisans in area N3 captured the Devils' fortress here and the portal-gates between areas 2 and 3 are set up, and a squad of harpies penetrates there.

Next, we go to D.Behemoths + Tree. Then the Minotaur Legion. Meanwhile, Partisans with Vamps (15 qty) were transferred for money from area 1 to area 3 and captured the lower fortress in the southeast. And this is where I tried to flee into it with the main hero - to hell with the harpies!! :) And with the vamps, break through the Hydrants and visit the quest hut. The battle is won!!! But I ran out of movement points :( And seeing that I didn't have time to replay the last two turns, I did the only possible thing - I slaughtered the Spawns of Evil at the gold mine, from whom I wanted to flee by destroying my BELOVED harpies :) Moreover, I slaughtered them sadistically slowly. After killing one squad, I gave them the chance to raise Goats from it, which I also destroyed to get more experience from the battle :) So that's it :) And then on the last movement point, I still flee to the fortress in the southeast to trade artifacts for oil :)
End of movie. Kyle - is this enough? I can answer any questions anyone may have.

Route in brief: High Elves(1-2-6), Scorpicors(1-3-4), Behemoths and Elementals(earth) (1-3-6), D.Behemoths(1-4-1), Minotaurs(1-4-3), Hydras and hut(south-east)(1-4-4), Hydras and hut2(north-east)(1-4-5), Giants + 2 trees (1-4-6) Two events fell out of the route (Gorgon m. and the required hut for them).

Well, let me torture you with questions :) Look what's happening:
1. Behemoths and Elementals(earth) - check
2. D.Behemoths - check
3. Minotaurs - check
4. Hydras and hut(north-east) - check
5. Hydras and hut2(south-east) - well, I was a few movement points short
6. Giants - check
7. 2 trees - check

Against point 5 (where I lacked moves), I put the Gorgon Legion + their hut + Spawns of Evil (hundred)

Plus, today I just played turn 1-4-7 excluding the Spawns of Evil but fought a battle with Vamps against Hydras(south-east) + hut. And still, it only turned out to be level 31 and the amount of experience points I wrote above in the posts. It turns out that in this layout I already have more meat for the Legion and + 1 hut (50000). But I don't reach level 32? Is it all because the trees were not visited last in the route ???

And another question. Your section of the route, namely: Minotaurs(1-4-3), Hydras and hut(south-east)(1-4-4) ???

Here is the map scheme:
1-2
4-3

As I understand it - Minotaurs is a Legion in area 3. How did you transfer from area 3 to area 2 ??? With an army ??? Did a computer player happen to be there? It's quite far from their area of activity - mostly they hang around fortresses, even neutral ones. Please clarify this point? In general, I'm interested in the transfers of strike forces specifically. Because judging by your route, you bounced around a lot between areas 2-3. Or is the route sequence described inaccurately ?
What do you say ?
