Walkthroughs for custom maps.

Good afternoon. The map is very interesting, but how did you manage to defeat the main 3 opponents? On day 2, the AI receives a full castle upgrade and 40 improved warriors of type 7 via script, resulting in 38 warriors of type 7 + 10 Azure Dragons on day 3. Usually, on day 1/3/7, the AI comes to you, and sometimes not just one, and it's impossible to defeat them.
I tried playing even on the easiest difficulty, but it doesn't change anything, and the AI always gets 38+10 on day 3.
Any ideas on how to beat this?

I continued the game and saw the problem. The enemies in this form are overwhelming (I still don't understand where the bonus of ten Azure Dragons comes from), which means we'll have to resort to guerrilla tactics. Our starting castle is inaccessible to the enemies, so the survival issue is not unsolvable. The Horn of Plenty hints at the priority of buying 1 Azure Dragon per week. The main thing is not to let the main hero fall into the enemy's clutches. The task is to steal the elemental spheres on the territory of each of the enemies, then take the captain's hat, while not forgetting to upgrade water magic, and then get the Badge of Courage on any of the 4 areas of the map. This is the main goal of the guerrilla tactics (it's no coincidence that the Badge of Courage is depicted on the drawn miniature of the map exactly where it is depicted), although here, perhaps, a more important point is to reach and destroy the Stone Golem at point 58.69.0. The items in this case are interconnected. Something like that.

In fact, it's not even clear why the AI only comes at the end of the month, because 40+10 is enough to wipe out 500 mages near the portals and then beat up the player.
And the author's idea with the purple pillars is also unclear; they seem to be an obstacle, but they can be bypassed through the nearest building (most often it's a Sphinx or a watering hole). As a result, it's either decoration, or the author didn't think this through on the map.

The enemies don't come right away because they have things to do at home. Regarding the pillars, I'm sure that's how it was intended. The goal is to confuse the player and force the AI to visit the Veil of Darkness, so that the game takes place in constant tension.

How?

What exactly confused you? You can swim past, joining that Crystal Dragon.

Judging by the word "Sphinx," I suspect you're playing the WoG version?

"Sphinx" in this case is the Veil of Darkness.

In general, the map is extremely confusing, and the author's style is very original. I haven't seen anything even remotely similar yet.
