Diablo Game Questions NA Hardcore - Can anyone provide me with the Diablo quest?

Hey guys, I talked a few buddies into playing hardcore this season, but I cannot get them to Master because they have never killed Diablo, and I don't have a single character that still has the quest.

Can anyone give me the quest? It could be on season or non-season, I don't care. I just want to get them playing with me.
