Which gate did you use?

The "Astral Gate" spell, which belongs to the "travel" spells, allows the hero to move over short distances, consuming half the daily movement points.
It was with their help that my hero crossed the phoenix outposts - you can also go through them in battle (and the battle is included), but it's too tedious without dark magic - all the units are stubborn: phoenixes have high initiative, you can't defend against the titans with their "lightning strikes" with either crystals or swords, the "chicken coop" doesn't work on the "chickens," and the seraphim have "divine punishment" - so until they spend mana on "punishing strike" or their chicken coop paralyzes, the elves cannot shoot.

The legitimacy and ethics of using the "Astral Gate" spell have already been discussed on page 2 of this thread. IMHO, there is nothing wrong with using them, especially since, as I already wrote, you cannot jump over the mountains that separate the upper and lower parts of the map; so you have to fight the monsters guarding the portal entrances in any case.
As for the center of the map, you can get there through portals guarded by Seraphim.

P.S. Damn, I just reread page 2 (after all, more than a year and a half have passed since the discussion) and found that the author did disable this spell in the latest version. And I didn't bother downloading it - I had several versions of the map in my archive, and it seems I unpacked not the latest one, where they were still available.

P.P.S. As for the miniatures, I just take a screenshot of the desired window and save the screenshot in any graphics editor as a jpg.
