Really nice flavorful chest. Curse immunity has needed some sort of counter for a very long time as it just shuts out an entire subset of builds.
I don't think the chest is overpowered at all, no elemental resists, pure evasion which is by far the least desirable defense, and obviously no life. People are overreacting as usual when they see a strong item that doesn't cater specifically to the builds they like playing. I'd be very happy to find this, would actually make a curse build for the first time ever.
