NHF – new heroes for Heroes V 3.1.

Otherwise, Necropolis will be overpowered. I built and built my city, but suddenly a Converter appears and destroys everything in your city.
Result: a twice-dead rusher and a city-type Necropolis.

I saved up and saved up my army, and then Wing killed everyone on his first turn. What a disappointment. :)
Wouldn't a hero, knowing his opponent, allow his city to be taken?
Besides, 95% of games end either in a final battle in the field or with the first city capture.
