VADER: How do the Chalice Dungeons work? I went through one of the Penum... (whatever) ones, got to the third floor down, killed the Boss and left. I removed the chalice from that gravestone and created a Penum ROOT dungeon, but it almost seems to be the same thing...(?)

Does Chalice Dungeon creation depend on the gravestone you use? Or, only on the Chalice and materials? Are you supposed to to remove them once you are done? There are five stones or so... are they only place-holders so you can build multiple dungeons or do the actual graves mean something?
