Please help to optimize build

Hi,
I'm playing crit cyclone CI occultist. I am able to clear T10 maps relatively safely, however I am unable to progress into higher tier maps as the defences are unfortunately lacking. Can someone point me how to improve my build? the only thing I can think of right now is to spend multiple exalts in gear to improve ES, apart from that I have no clue.

Damage on Full Life is added in PoB to substitute missing calculation of Close Combat

You should be running discipline as CI build (even if that means having to reshuffle your aura setup), and your chest / boots have low amount of ES, none of your jewels have ES on them, also you're skipping big ES nodes like Foresight, Essence Surge and Utmost Intellect.

Unfortunately with 4,4k ES I don't think you can get to end game, I don't know if this is a "homemade" build or taken from someone's else guide, but tbh I feel crit builds always struggle to build defenses because they spend lots of item budget on crit / crit multi. It's the same problem with life-based crit builds.

Especially a build that has to use a 2h weapon and doesn't utilize a shield.

Hi, thanks for your comment.

Chest ES - I am aware of that, unfortunately for chest to have high ES + crit to attacks is becoming very expensive (about 4 ex for a chest with crit and 550 ES currently)

The build is entirely self-made to play the melee witch archetype (originally designed for flicker strike, but it feels clumsy at the moment).

Current PoB after changes - https://pastebin.com/6f5dhPyp

Survivability feels a lot better with 6.2k ES, however I'll need to get about 200-300k DPS for the build to feel great again.

Thank you for your suggestions
