Does anyone know in which RPK to find the number of / specifics of background traits added to a generic hero-for-hire? I would like to increase the number of backgrounds (randomly, if possible) in order to make the heroes more unique instead of every hero being exactly the same (apart from class) as the next and introduce a bit of luck in the selection. Also, I have a problem making the background traits show in the first place, although that might be a different story.
