Hit a progression wall. Could use a hand =)

Hello there. First post ever.

Here's my PoB Pastebin: https://pastebin.com/pxWYCkg0

Further explanation within "Notes" in PoB.

In summary: Not enough damage. Need help.

Thank you in advance! =)

I'm not an expert on soulrend, but here's a few thoughts:

You don't need Combustion or Faster Casting in Flame Dash. I suggest you get a rank 6-7 Arcane Surge linked to it instead.

Try and fit a Malevolence aura and Discipline aura in somewhere. You might need to link them to an Enlighten.

Wither is great. Put it on a totem with multi totem support.

Your single target should generally be the 6-link, but since you're using Unravelling that might be difficult.

You need ~300% ES from tree, not 200% You generally want between 5-6k ES in a CI build when you start doing endgame.

You seem to want to go the mana route, so I suggest you at least try and get Utmost Intellect for better int-stacking. It'll also help you with ES.

The 6 points you have going out to Arcanist's Dominion are better spent elsewhere.

It looks like you're spreading your sources of damage across too many skills. What does Vaal Blight Really do for the build? Bane is good enough on its own for clear. You could also consider putting a GMP on soulrend for clear and swap it out for bosses.

Your large cluster jewel should probably be a chaos damage one with Dark Ideation, Misery Everlasting or Wicked Pall as prefixes, and Unspeakable Gifts as the suffix.

Swap your Eldritch Knowledge jewel out with a rare on with DoT multi and %ES on it. Same with Spreading Rot (and have a wither totem setup). Fevered mind also does almost nothing for you. "Increased damage" is additive, not a multiplier. You'll want MORE damage mods instead. Dot multi is also a multiplier (but still additive). You should find a couple of Abyss jewels with +ES and res on them (to free up suffixes on other equipment), and +mana last.

You should not be using that many unique flasks unless you have ailment immunity. Get rid of the Overflowing Chalice at the very least. And do you really need Soul Catcher? I recommend you get an Experimenter's Quicksilver of Adrenaline, and get a staunching utility flask instead of one of your other ones. You probably need a warding flask as well. You can either get a flask of heat, or bench craft cannot be frozen on boots (if you have access to it and can afford it), then you can swap out the Dream Fragments.

the 2 attack affixes on your amulet could be something else.
Ring 2 could easily be upgraded to something much better.

A Shaper base int armor has the %max mana prefix and %max int suffix in the affix pool.

If you can find some Hunter boots with +2 to chaos gems and Tailwind on them, that will help a lot too.

Elder Gloves has chaos dot multi in their suffix pool.

In terms of what affixes are possible on different bases, you can refer to this site and search trade accordingly: https://www.craftofexile.com/

Okay, I fiddled a bit with your PoB. I didn't do much with your gear, just passives and jewels: https://pastebin.com/iy2uTQcv Some of the clusters might be difficult to get, but 7.7k ES is going to hold up just fine. You might need to take a 30 Dex node to fit some of your gems.

There's probably plenty of optimization to be done on the tree in terms of squeezing out more dps. :)
