I really like the metaphysics tree concept, I'm trying to earn some madness currency munching down drugs, using the crown and hanging around a small dwelling on a nightmare atropus planet. Around the 800 madness gained, i notice the currency earning slows down to the point natural degradation starts pushing back sometimes stalling it around 870 or 900. At this point i return to the ship to dissect some corpses and craft more food, but beaming down to the planet still doesn't feel as "fresh" enough to earn more madness as say, doing so from below 100 madness, so after 30 minutes or so, i leave the planet with around 1200 madness having lost around 20%-30% of the madness picked up according to the toastes. I have zero protheon on me btw, my character is a Floran.
