Questions about National Heroes

With regard to the latter, I've read people saying that in Dom I you need to have a positive luck scale in order to get your heroes, but I didn't find this to be true. In fact I found my national heroes showing up just as often with luck 0 as with luck +3. How is it in Dom II?

In Dom 1, I think that you have to have at least Luck-1 to have any national heroes. Or is it luck larger than -1? Anybody can confirm?
