NHF – new heroes for Heroes V 3.1.

Who are these?))) Can you provide more details?

These are upgraded Orcish Warriors from the NCF megapack. I don't remember their exact stats, but I do remember that they have a speed of 7 and the abilities "Mana Drain" and "Demon." Their advantages over Fire Demons are obvious: they are Orcs, and they can be converted into another upgrade if needed.
