I'm kinda answering my own question from a week ago, but in case someone else is wondering:
Masochism level makes You/increases pleasure gain from being attacked by enemies
Sadism level makes You/increases pleasure gain from attacking enemies
Though I don't know if Masochis and Sadism level have any other effect
What is the exact effect of using the Submit to Nerds" edict, specifically the "Permanently affected by expose weakness"? Is it a big deal?
In combat nerds can use "expose weakness" skill, that normaly lasts 5 turns or so and gives Karryn minor debuffs to some of her resists. So if You choose "Submit to nerds" eddict, that effect will last indefinitely, untill You defeat a wave.
So, it will do two things:
One - make prelonged combat and bar side job slightly harder.
