6. You can ressurect them with evlin spell. Stoneskin is a must.
I havent go for no loss campaign but i was able to play with only blackies on imposssible. Even on nameless/shettera while striking there just after rusty anchor !! ( dont have to say that many players would suffer badly at verona at this point)
Few hardest heroes like Vlad vegeto, or that demon in castle in Shettera were too hard but only a few. I beat for example von cracow with no loss, while hes army was like 15 times larger in case of leadership. Black Knights just owns
