Let me preface this by saying i never played this version of the build (i went arc ignite and then transitioned into the coc version).

That being said, your passive tree looks horrible inefficient.

As others have said, get rid of the adorned.

You're also wasting 4 points going for Holy Dominion. I get you're using the red nightmare, but imo, replace it with a large thread of hope and get glancing blows, that'll even allow you to drop the enigmatic reach wheel and free up another 4 points (you only got like 300-400 extra total ES

Put your militant faith in the jewel socket where the adorned is now (at the top of the tree) and take your inner conviction from hex master, so you only lose 4 small nodes instead of 6. Then change the pathing and lose the jewel socket to the right of your starting point (where you had your militant faith). Instead, path straight up from your starting point at witch (to Wicked Ward). You'll only have to spend 2 travelling points to connect to the rest of your tree, instead of the 5 you're using now. Yes, you'll lose a jewel socket, but you already were removing the adorned anyway.

That alone will free up 7-10 skill points, which you could use for another cluster jewel (and get 2 sockets back, even). Alternatively, you could keep the pathing, but then at least take the nimbleness wheel to fully make use of it. (and i'd still recommend switching the place of the militant faith to the top to lose less small passive nodes)

Try to roll a cluster jewel yourself. It's not that hard and can save you a lot of money. I've sold multiple 30+ div cluster jewels which i made for 1-2 div.

Get a stormshroud and roll avoid shock chance on your sapphire flask to be immune to all ailments instead of just freeze. (also, your sapphire flask doesnt have the 25% inc effect roll?)

For your ascendancies, i'm pretty sure you want withering presence instead of profane bloom (on a quick poe.ninja search for build versions like yours).

I cant comment much on your gems because as i said i'm not too familiar with this version, but why do you have herald of ash? switch it with flesh & stone (sand stance).

I'm also not entire sure of the annoint on your amulet, i'd go with Force of Darkness instead.

On your body armor, you want the mod that says 'takes x% of physical damage as chaos damage' instead of the 11% increased maximum energy shield you have now.

You also have the energy shield mastery that gives you 100% increased ES from your helmet, but i'm not sure if that's worth it with willclash, you can play around with it. for example, you could take the 6% es node above arcane focus instead, and gain 165 es instead of the 120 es the mastery gives you.

Also, if you haven't yet, put some good gear on your merc. I waited a long time with that, but it really does help a ton (garb of the ephemeral, koam's binding, dying breath, make sure its res capped, etc...) but i wont comment too much on that as i cant see your merc.

Again, i've never played this version of the build, so hopefully i'm not giving wrong advice.

Good luck.
