I've started doing some chalice dungeons in Bloodborne and I'm a little uncertain as to what to do once I have cleared them. There doesn't seem to be much help on it in the game (like everything else) so I'm not sure what I should be doing when I've got to the third level and killed the boss (And explored all side areas).
I have the option to remove the chalice but it occurs to me there might be a reason why it doesn't just go once you have completed it. Is there a way to restart it? Is there a way to do anything else? Or once I've killed and looted everything do i just remove it and start a new one?
