Duelist Champion build help

Hello!

I came back to Poe after a long time (last time I played at lauch Fall of Oriath) and started playing duelist/champion My problem is that while I am able to stick out a lot my dps starts to be too weak when hitting bosses on t15/t16 maps and I have a hard time doing the breaches I wanted to focus on. Does anyone have any idea what can be changed to boost overal dmg?

Link to my current build: https://poe.ninja/builds/settlers/character/d0t3rhshs/Doterro?type=exp&i=59&search=skills%3DLacerate%26sort%3Ddps

How much of your damage is physical/ non physical. Hard to say exactly without looking at the POB, but im not sure if Rebuke the vaal and bleed/impales is the best combination? Seems like it might be going in a few too many directions. Maybe my advice is incorrect, hard to know without seeing the damage break down, just one thing I would take a look at. (I can see this breakdown is viewable profile dps estimation. With most you damage being physical and build having bleed/impales, wondering if pure physical weapon would be better.)

Something that has been added since you last played is eldritch mods, you don't have any on your gear, that might help as they are pretty strong. The rage rework this league is pretty good for attack builds as well, that might be something to look at getting. You are pretty close to rage nodes on the tree if you don't already have a way of generating it. I think your gear can be upgraded as a whole, might be one too many unique items. In particular I'm just not sure about the weapon. It is a pretty good on some builds, you are able to scale all the damage types, I just wonder if there could be more synergy with full physical or if there is other options.

Why lacerate exactly? Will it be good for breach? I haven't played it much before, I guess it's ok if it has enough AOE? Just wondering if that skill is a good fit for the build or not.
Profile is showing a lot of empty skill slots. If they are not being used maybe look at adding some more mechanics in. Are you proccing your adrenalin? That might be useful if isn't getting close to full uptime.

Have to agree with Belegur.

Ur build is kinda all over the place. U're using Impale which only works on physical damage, but ur weapon has a lot of chaos and elemental damage.

U're using Cruelty Support for some reason instead of a better support like Impale Support or Brutality Support. (which would make ur non-physical damage useless aswell)

Ur Ascendency points are also not that good imo.
Unstoppable Hero got changed and doesn't do anything for ur character anymore. It only affects allies and minions. I'd rather spec out of "Unstoppable Hero" and "First to strike, last to Fall" and take worthy foe instead. That way u might not need resolute technique aswell.

There's certainly more to fix, like all those unused gem sockets aswell.
