Could use help with this homebrew (endgame)

I’ve been working on a no guide build using skills I enjoy using and it’s been working great up until T15-16 map bosses. https://poe2.ninja/pob/8aec

I can clear wave after wave of mobs white through gold with ease but once I have to fight any map boss I barely do any damage, it takes upwards of 5 minutes to take down a boss.

Is there anything I could possibly do to try and get this build to boss clearing level while still maintains the core skills I enjoy most? (Armour piercing rounds and High Velocity rounds) I was aiming for an all physical dmg little to no elemental dmg build but things aren’t working out when it comes to bossing.

Basically my attacking pattern is: huh down all mobs with surmount piercing bullets, toss flash bang into really thick mobs, use artillery totems for exceptionally thick mobs and breaches and such.

For bossing I use all of these skills plus High Velocity Rounds in an attempt to build up pin (immobilize) and impale (extra damage added to HVR) to try and inflict a big hit of poison and try and drain bossnhealth as quickly as I can on rares and others. Only the HVR deals damage just as fast as Armour Piercing Rounds so it’s kinda pointless to even use it at this point…


Could someone with better knowledge than myself take a look and see if there’s something obvious I’m missing or is this build pretty much doomed to bricks?

Edit: I have moved some things around and grabbed all the “low life” nodes around Stars Aligned.

Any feedback is greatly appreciated!

Imho problem is trying to spec in 2 things, poison AND balista. So neither is rly good. When you make build, you should always think about bosses (single target) first as its the real problem, you can always somehow figure out how to AoE mobs from boss build.

If you go full balista, you can strip alot of points from poison skills. If you focus on poison, you could swap ascendency for Solid Plan and get some extra spirit gems in.

If you are rly into poison, try Plague Bearer. When i was making pure poison build (https://www.pathofexile.com/forum/view-thread/3784785) i ignored this gem, but once i found out its potency, it became very fast my favorite skill for poison. Hits like truck, huge AoE (with mag. effect support) and it apply HUGE poison (which can be spread by plague herald). It works against mobs and boss alike (you can even boost it for boss with concentrated effect and astral projection, which lose almost all AoE area, but hits much harder).

I have also encountered a similar problem. Have you solved your problem?

Which problem? My biggest issue is that it seems like High Velocity Rounds doesn’t do the 2000% more dmg when consuming fully broken armor. I can’t get the build to work or I’m missing something major… I’ve pretty much given up and am waiting for the next update to see if anything changes.
