I’ve been farming Chaos Armors for two weeks straight, specifically looking for Scoundrel’s Leathers, and it just won’t drop — not the helm, gloves, pants, or boots.
I’m about to smash my PC; this can’t be normal!
I can assure you, they do drop, you just gotta keep farming.
Meanwhile, just use the regular unique. Chaos armors are fun, but not needed for your build to function.
