Hi samatron,
we have a long weekend here in Ukraine,
and I finally had the chance to play your map.
The map is excellent, although I haven't finished it yet.
The map has been given a local name: "Northern Wind" or "He who was nothing will become everything." Let me explain why. I started playing as Inferno. I took Aiden and, as expected, started developing him. At the same time, as Aiden improved, I also recruited other heroes and leveled them up a bit; they served as a force to clear the territory, and if there were weak enemy heroes, they would defeat them, or they would be defeated. Accordingly, I chose heroes based on specific factions.
This also happened with Necropolis. But by this time, I had collected the artifacts Cursed Armor, Unholy Cloak, and Vulnerability Medal. In short, my Necropolis hero began to develop rapidly and surpassed my main hero.
And let's be honest, defeating almost 5000 Crystal Dragons is unrealistic if you're fighting 100 of them, no matter how super your warrior is,
but a swarm of liches took them down in three turns.
Therefore, a seemingly weak Necromancer hero turned out to be the most powerful by the middle of the game. :)
That's how it happened.
