The traits in question that I’ve found are affected by these are:
8-10% dmg against elites
8-10% dmg against poxwalkers/groaners
I assume the other 8-10% ones are bugged as well, like against specialists
the 20%-25% ones are unaffected I believe
Like the title says, those traits, instead of giving you 8-10% dmg, they give you 80-100% dmg, which is pretty broken in most cases.
It’s a pain to do the numbers with.
