Madness

ABOUT SANITY
In Frackin' Universe, some things are hidden from the masses.

But then, perhaps ignorance is bliss. After all, knowing too much can lead to dark paths and physical detriments...

Then again, who says that one should curse the dark when they can light the candle-flame of knowledge?

How to become mad

 * Talk to Kevin (pink-haired Mantizi scientist at the Science Outpost). He is very mad, and if you do his quests, you will be too.
 * Walk around on Atropus and Nightmare Atropus planets (unless you are a Thelusian - they are immune to Maddening Atmosphere) or wear Crown of the Idiot. You'll suffer random debuffs.
 * Find some cadavers (often dropped by NPC bandits from those "deal with bandits" tenant quests), and perform autopsies on them (Kevin's lab has an Autopsy Table).
 * Write (and then read) weird/perverted books at Tome Dais station.
 * Get bitten by maddening creatures like Caerbannog or Penumbral 'Troid.
 * Eat disgusting foods like Bloody Corpse Waffles.

How to lose madness

 * Spend it: research some nodes of Metaphysics tree. Also craft weird things like Psionic Battery. You need to be quite mad to do these things, and required Madness is consumed in the process.
 * Visit Insta-Freud (there is one at the Science Outpost), you rapidly lose accumulated madness when inside.
 * Carry around a lot of unspent Protheon. It increases the rate of madness loss.
