Autopsy Table

Autopsy Table allows you to dig into corpses and find out what's inside. Yuck. Depending on the "inputs", you can get some Madness out of it.

Corpses (cadavers) are often dropped by NPC bandits. You can find them in some dungeons (such as Floran prison) or by accepting tenant quests like "deal with bandits". Performing an autopsy on 25 cadavers is enough to get 200 Madness that are necessary for the first node of Metaphysics tree (beware that Madness currency decays over time, but it won't start decaying when still stored inside the Autopsy Table, only after you retrieve it).

There is a usable Autopsy Table at the Science Outpost. It belongs to Kevin, who totally doesn't mind when other people perform autopsies in his room.
