Traits are not fully implemented yet. They are only -1, 0, or 1 instead of accumulating, and some of them can only be raised through a single method like some random village quest you might never find.
I'd also like to see a little more visibility on how these traits are generated during character creation, and what actions make them switch between -1, 0, and 1. I'm sure that info is out there somewhere, but I have yet to stumble across it, and it certainly isn't very transparent in game.
As an example, my current character started with Honor, Mercy, and Generous at start. I'm now just Generous. I have zero clue what I did in character creation to start with those traits, nor whatever I did to drop to neutral in two of them.
Huh...indeed they do. Skimmed through them all again, I'd never registered that; guess that's what I get for only focusing on the left side of the screen for focus/attribute points.
I did also notice, all the trait selections occur on the various choices in the Young Adulthood step...didn't see any trait characteristics in any of the other choices before/after (not with a Vlandia culture start, anyway).
