Agrippa's tonic is driving me nuts

[nofsky]

You can find all the ingredients even after you get locked up in prison.

There is a new well on the top floor where you can lower the meat to get the bone with mucus.
There's some fungi that you can get the poison gland from in one of the collapsed corridors that used to lead to one of the torture areas.
There's a well with blood in the room that opened up near Agrippa. This room also has string if you didn't pick up that.
