List of traits for equipment?

So I just dropped 10 orange dust trying to get a scavenger trait on my repeating crossbow, but it just jumped back and forth between hunter and inspirational shot. I’m beginning to think scavenger is not an option for that weapon, but I was thinking maybe it would be good to have a list somewhere of possible traits? Maybe a book or something in the keep or in each character’s room about their weapons would be cool.
