Well, completing the second campaign didn't cause me any difficulties – it's just a series of quests where you simply need to go from one character to another....
Next, the first campaign, first map... I completed all seven tasks without any problems.
The only thing I needed was to choose the fire spellbook – it has the Blind spell – which will be useful on the second map. For some reason, the air spellbook is buggy – instead of giving a speed boost, it gives a Destruction Beam spell... Probably a bug.
Difficulties arose in the first campaign, second map...
1. It is necessary to visit the Flag of Unity and dismiss the Spearman in order to reach the garrison.
2. It is necessary to multiply the Ghosts as much as possible on the Peasants, then on the Gnomes, and then on the Skeletons – the total number of Ghosts at the end of the map reached about 1800 units. It could have been more, but I was already very tired of playing)).

3. I maxed out the hero – I was even able to defeat the Dragons in the left part of the map in the middle.
Further... It wasn't the most difficult map, I must say... These messengers of the gods give good modifiers; you just need to get them in the second month.... Therefore, I built only 2 cities – the ones with Phoenixes and Titans. Moreover, I built them only to get the upgraded Phoenixes and Titans... And only to capture the messengers with two heroes, and then I simply transferred them to two other heroes. So, by the time I approached the teleporters, I had about 8 Phoenixes and 8 Titans with two heroes, and the other two had almost no army... This is not important, actually. After teleporting, I captured 2 cities – the city with Archangels and the city with Yellow Dragons... It was not immediately possible to capture the Dungeon and the Three-Headed Hydras – as you remember, two heroes had no army... But then, having received 4 cities almost for free, I built three more cities again – Phoenixes, Behemoths, and Titans – I built upgrade buildings only for the last three units. After that, having accumulated about 22 Archangels and 15 Titans with one hero – and also having increased the spell power of all 4 heroes to at least 12, and having taught the Clone spell to all four heroes, I captured the Dungeon and the Three-Headed Hydras, and at the same time, I learned another good spell, Explosion, again with all four heroes. This was very useful later.
Well, and I started accumulating an army... an example is in the attachment...
