There's a list of common traits for each faction. While anyone can get these traits, some are more common in a particular faction. However, this list is not necessarily readily available on the wiki, nor is it really the first place someone might look. So I wanted to make a thing here for quick references for the factions and their common traits, as well as what the traits do.

thank you so much the wiki is flooded with ads
In terms of content it is a good wiki, but fandom is difficult sometimes
jagged solar
Wow; this is really useful to have collated like this! (okay, and also I'm sort of bumping it, because it feels like it deserves to get starred)
jagged solar
So, uh, weird question, but... Does Brute cascade? Or is it just a single proc? I've seen some weird morale cascades when a dice pool with few contributors misses, and I'm wondering if that is caused by long Brute chains.
broken elk
As far as I know, it can cascade.
I know for a while, merciless was a notable one that would cause a lot of problems with how common it was.
jagged solar
I thought merciless just triggered all at once? Brute's danger is that it can happen randomly on a bad roll.
broken elk
True. Regardless, I don't know for sure, but I believe that Brute, if it causes someone with Brute to lose morale, can cause even more people to lose morale as a result.
