Demon invasion.

Finally, I managed to more or less successfully complete half of the first mission, although I couldn't finish it due to endless replays with the awful stacks of dwarves that are everywhere. Well, and, accordingly, very useful (but not necessarily) subjective feedback :D

I wrote above about randomness, but I realized that I greatly underestimated it in this map. Level up to 3 - hello, education; cleared everything around the castle up to the assassins at the center - 7 (!!!!) points appeared in speed. Just 7 raw points of magic power and +3 from the artifact, yes, I was crushing everything alive. I defeat the hunters, hello, strength under the protection of un-nerfed titans. In general, I disintegrate everything alive on my path with one or two waves of fire and the apotheosis of a cloak with +50% fire damage, just, curtain, 21 speed, 1140 damage from a wave of burning. Of course, I knock down the door to other demons and, with the initial stack of imps, I complete the first part of the map in 2 months and 1 week without even entering my castle.

The second part of the map, the stats are distributed as 2 0 3 2, there are absolutely harmless stacks around, like swordsmen and liches, and, just like a cherry on top - again, I got a level up after level 4, and there was also an artifact worth 1k gold guarded by un-nerfed skeletal dragons. Of course, I clear everything that was there before the reinforcements from the Chaos Citadel and finally get to the main gameplay of this mission. However, at this point, my luck in the casino ran out, and I also made one big mistake when I tried to catch the leadership skill again and go through spells again, but nothing came of it, I couldn't find any artifacts for speed, nor the leadership skill itself. I went into darkness - not a single decent high-level spell (managing to catch Unholy Word from the other 5th-level spells and Dragon Utopia at the same time - this is clearly a great start), in short, the build is depressing, I didn't manage to find any useful artifacts (the ring for machines was nice in the cart), the battles were extremely difficult and slow, I had to replay a lot, and in the end, I gave up on the second garrison before the coveted mentor.

In general, to summarize, author, if you are going to update the campaign, I really ask you to make it less dependent on luck. Given that the gameplay of this map assumes a build exclusively through magical power and 3 spells, some suggestions could be: a scripted sorceress with protection/level up at the beginning, points for +1 speed, maybe certain artifacts are needed, and in general, all custom stacks behind the garrisons and with 7th-level creatures, because sometimes, as soon as they spawn, it's immediately clear that they can't be defeated (in the tower of the sorceress, unicorns spawned, djinn 75%, on strong artifacts, devils and elven dragons, etc.). The map is very and VERY dependent on the distribution of points in characteristics, the ideal start is described above, but before that, there were 3 unsuccessful attempts, and in one, it turned out that after 20 levels, only 1 (!!!!!!) point appeared in speed, and in the end, there were 4 (3 from the artifact) to clear the nasty stacks behind the garrisons. And then, I won't claim, based on my unprofessional knowledge of combat skills, but either the stacks (20+ infernal titans with spells), or at least their number (~50 x3 angels (?!?!)) at the portal and library would also be good to change, because they are only defeated under ideal conditions, both in terms of the build and the battlefield (and what kind of trash is happening on heroic difficulty is terrible to think about).

Then, the second part of the map on the surface also desperately needs clearly defined stacks and maybe artifacts, because one bad spawn, and you go to restart. An unsuccessful distribution of points, and you go to clear hundreds of units with 1 speed. Then, the small amount of magic in the hero (if, of course, you were not lucky with the basic distribution) gives almost no chance to break through the garrisons with magic without unpleasant losses, and playing immediately through the army and reinforcements from the Chaos Citadel is months of waiting, and the opponent has legions at the end. I won't claim, but the mentor, at least one garrison closer, would give hope for correcting mistakes and more advantageous builds at the beginning (and considering what will drop in the guilds from spells, it's a whole field of wonders, so it's simply impossible to predict the corresponding build), and maybe something should be done with the portal stack too (22 immune to magic dragons and flying across the battlefield make you fight in tears, not to mention the rest of the crowd).

Of course, everything above is the point of view of an amateur without deep knowledge of secret tactics, playing as a warrior, and whose ceiling is abusing darkness and raising the dead with BDP*:D, but I was comfortable playing at the same difficulty level and the previous campaign without any particular problems and restarts, so I sincerely hope for improvement and greater playability without losing complexity and interest.
