Protheon

Protheon is a mysterious currency. It represents your insight into ancient knowledge.


 * You can exchange 1 Protheon for 500 Research (at Munchies' Dirt).
 * You can keep Protheon unspent, which increases your "over the time" research gain by +1 for each 10 Protheon that you have. Maximum bonus is +10 (at 100 Protheon).
 * Protheon increases the efficiency of Insta-Freud (you lose unwanted Madness faster).

As a downside, having a lot of unspent Protheon turns you into a very reasonable and scientific person, which reduces the Madness gain over time (from being on Atropus worlds, etc.).
