Uninvited guests.

For the sake of the experiment, I deleted all the maps. A specialist in mega-units appeared almost immediately. There was probably a conflict between the mods. Each race has its own strong stack of creatures. For Necromancers, it's zombies; for Orcs, it's warmongers; for Humans, it's infantry, and so on. With a developed defense skill and artifacts that boost HP, armor, and resistance, they can hold out for quite a while. Fury helps them in this regard. The only downside is that it's difficult to increase their mobility and initiative. You need to choose the right artifacts and skills for that. You can defeat a numerically superior enemy with small, but frequent attacks. Light magic, advanced morale... This is the opposite of dark magic and destruction. For some time, I underestimated the "Spellcasting" skill. But then, on one of the maps, I got this skill. The opponent didn't have time to attack, while my hero was closing the spellbook. I'll also play through this map with humans, depending on my mood.
