You need the "Crucible of Faith" from the old lady in the sub-basement.
It gets you into the room and it is what you mix the elixir in on the
Altar.
to enter the room with the lion's head, you also need the "Crucible of
Faith" There are only two chest in there, save before you open them, for
when you open one of the chests, the other explodes
SPOILER>>SPOILER SPOILER>>>>>
One of the keys from the 3rd floor opens a door to the basement. You will have
to Face your greed (put the weapons in the little niches) and talk to the
old woman. She will give you the crucible of faith then you can take the weapons
as you leave and get the goodies out of the 3rd floor if you want to. (it is a pretty
good set of armour). You dont need to go back up there though if you don't want to.
