Searches of the lost city

Finally, I finished playing this map after a short break.
The main thing: I liked the map! You need to keep in mind that I don't like "Impossible" difficulty (this is the 3rd one I've completed out of those). And from the very beginning, I didn't believe I could do it. But when I did!.. I've never gotten almost 1.5 million experience points in a single battle before! And by the way, the result took the top spot in the leaderboard; all the previous ones were much more modest.
I won by fulfilling the first condition: I captured Mazata and placed the Grail there. I tried to defeat the remaining enemies, but the battle with Valeska (pink) cost me too many of my troops, and with the army and skills I had, I couldn't defeat Axis (orange) and Nagash (pink).
What's good (in my opinion):
1. There's no dictation from the author: the player is free to choose both the method of victory and the path to take. The Seers give side quests, which are not required to complete. The Guardians can be bypassed by obtaining the Wings of the Angel (I even regretted taking them: if I had known where they were, I would have been flying around for a long time). Personally, I didn't give anything to anyone, I just received a gift from a Seer for having initial skills of 40+.
2. There are many artifacts, some even 2-3 of each. Everything you could wish for. I collected 2 Legion Statues, 2 or 3 Horns of Plenty.
3. There are enough "enhancements" in the Dungeon (Libraries of Enlightenment, Arenas).
4. There are also plenty of monsters to level up.
Now about hiding the monoliths behind volcanoes: on the one hand, it seems like an original idea (I haven't seen anything like it yet), but on the other hand, you have to look for them! Pixel-hunting is not a very pleasant activity, especially in "Heroes." Besides, there's no other way to get to Mazata.
What personally bothers me:
1. The deliberately rectangular landscape.
2. Inferno on patches of clover among the lava. It's supposed to be funny, I guess...
What remains unclear: How did Orange (Axis) manage to get 700+ Phoenixes, if, in theory, the Phoenixes are all placed as guards? I even checked in the editor later: he definitely took them from the Blue Tent, but that's impossible, because they are set not to join! But this is a question for WoG, not for you, Samatron (as I already said, I play everything in WoG: it's more interesting).
My final rating (the answer options in the poll are not very detailed): approximately 8.5 out of 10. That is, "very good, except for minor comments."
I wish you many more interesting maps! Keep making them!
Now I'm playing your "Island of the Little Skull."
