You have a chance of getting in divines from tel var lockbox vendors (and greater lockbox). For level 10- Cp 150 it's 600 stones and Cp 160 it's 3k stones per box if I remember correctly.
Well yea, the tel var boxes is how you get other traits than impen. Rng which piece you get and which trait. Though I am not sure if all traits are in the loot tables. I think I heard someone say once that for example sturdy isn't on it. But just hearsay.
Went by a website that seems to hold the incorrect into. Will note the elder scrolls wiki is not the place to go and Google is not alway right. But hey, it served a purpose. Sallington for to post that silly image. Lol.
