And looking at this mini-report, I can say the following:
1) Choose the moment for casting spells more carefully, try to cast them so that they are not immediately interrupted before they take effect.
2) Install version 3.51. It won't be interesting to fight if you have a city portal or hypnosis in your spellbook, and the guardian angel will be at level 4.
3) It's better to use Crusaders to eliminate enemy heroes, especially if they can be killed in one hit. That is, first hit -> immortality potion -> 2nd hit -> final death of the hero.
4) Don't forget to douse the corpses of enemy heroes with acid so that you are not surprised by the sudden resurrection of a previously killed enemy using sacrifice, for example.
5) Antimagic is only useful if you have an advantage in troops.
6) Order mages are useful for stealing spells, slowing down, berserks (by the way, it perfectly replaces any confusion or hornet's nest), removing spells (sometimes it's more profitable than a general steal and destroys illusions), and blinding.
That's all for now:o

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
