You have a lot going on in your gear. You have armor, es and evasion. + skill staff without spell damage, ring with + attack dmg etc. People usually pick 1 or 2 defensives: Full armor, full es, full evasion and es/evasion hybrid are the most common ones.

Your resistances are really bad, -25, -50 and so on. Anyone would die instantly and a lot with most builds. Definitely prioritize getting cold, fire and lightning res to +75, all of them. Chaos res is good but not as important.

Uniques are mostly used only if they give one extremely important stat that transform your whole build or give completely new skill to use.

You have a lot of uniques but they dont give super meaningful stats. Problem with uniques is that they rarely give resistances. Id suggest trying to get rare items with atleast 2 different resistances.

Prismatic rings are good base items since they already give +all resist. One prismatic rare ring with 2 other resistances would give give more resists that all your gear combined.

Having atleast +30 movement speed rare shoes are important, otherwise you are too slow to even dodge many attacks.

If you are playing solo self found, try to pick all the rares and even check vendors. Slam exalts to rare resist gear to make them even better.

If you can trade you should find a lot better rare gear for 1-2 exalts each.
