NHF – new heroes for Heroes V 3.1.

What if you created a dwarf hero with an ability similar to Tolgarov's, but with a different rune?

Yes, but with any rune, it would be overpowered.
Plus, the in-game display is not great.

By the way, regarding dark dwarves:
In the mod, all races will have all starting skills summed up across their heroes.

However, dwarves currently lack a hero specializing in darkness.
I'd like to come up with a special hero, and also have an icon and a hero model.
