Hi,
my first real Barb in Diablo 4. And i have to say, english is not my first language, so please be calm. 
I wanted to try out the new mythic item Shattered Vow with Andariel’s Visage and a Rend/Overpower build.
My damage output in the pit lvl 45 is underwhelming. I use fist of fate with GA lucky hit and GA random effect.
Aspects: LH: bleed stuns vulnerable, stunned enemies tale bleed damage as physical, berserking deals bleed, creeping death and rupture oil.
Armor is a Tyraels so survivability is no problem. Shoes are Yens blessing at the moment and pants are Tibaults. Most gear masterworked 4-8.
Skills: Rend, Rupture and as passive Gushing Wounds. Also the passive Skills which increase the bleeddamage.
I tempered Rend hits twice and critical strike damage on my wepons and at the moment critical strike damge also on rings/amulet.
Armor is a Tyraels so survivability is no problem.
GS chance is at the moment 40% Crit damge 1200%. Damage with bleed 1140 %.
What i’m missing? Like i said, the output is really underwehelming to puit it mildly.
The paragon board seems also not to much improvement for bleeding.
Andariels triggers constantly but not enough for tons of damage. Attack speed is only 61%. I attack with the 2 handed weapon. Also bleed damage seems so little and i would say, that after casting rend several times in a row, the bleeding damage does not seem to stack, it is constantly 3-4 mm of the monsters (elite/boss) health bar.
I’m not using any guides or youtube videos so is it maybe only one item i miss, which i haven’t found. A unique of a lair boss or why is the damage output so low?
Thx for answers and help
40% crit chance is way to low and crit damage doesn’t matter or shouldn’t be that important i tried to make gushing wounds work last season but couldn’t i haven’t tried yet this season quite the mystery to unlock. i dont understand if it procs whenever you apply a bleed or stack them or just when you first make them bleed because the wording is horrid. i tried using 2h sword and whirlwinds bleed change and lunging strikes bleed at the same time rend performed the best but was always bad damage vs any other key passive.
If you wanna run a bleed build you need 100% crt chance and damage over time
Your build is conflicted. If you want to scale Andy’s, you want to stay away from bleed mods/multipliers, except for damage vs bleeding.
Your best bet is to stack generic damage multipliers, vulnerable, close, and dot damage. The thing is, Barbs have zero multipliers for dot, only bleed.
Gushing Wounds only applies to bleed, so you’d be better off with Unconstrained.
If you’re dead set on mixing bleed and poison, it’s more effective to use Ravenous ring to apply Rend, and use Lunging to proc Andy’s.
i heard lunging strike works extremely well with stacking lucky hits per application or per tick can it proc xfals?
Do you want to try to build Damage Over Time using Andariels and Shattered Vow? You could try Hellhammer, Inevitable Fate, Creeping Death, Elements maybe.
The problem with Andariels is the Poison Nova has very little synergy and support for Barbarian to make it deal respectable damage. If the Poison Nova scaled with Strength similar to how Burning Damage with Hellhammer - it would be more interesting. Rupture also scales well with Strength. You might have something there then with Rupture and Upheaval. IAS from Rupture works well with Upheaval.
Thx for the thoughts.
I know, that Andy is not pushed by any Skills or Passives. Even the glyphs are phys damage over time.
I wanted Andy as support for bleed. The last two seasons Andy was great even for chars/builds, that didn’t push poison damage. But here the damage is way to low at the moment for me and it procs constant but not often enough. I have nearly 100% lucky hit with flay and 70 % with rend.
But the main problem is my way to low bleed damage. And yeah 40% crit chance is too low, i know, working on that, but didn’t find any good amulets or rings with this affix so far.
Why is crit damage not important? In gushing wounds, the bleed damage is increased by 70% multiplicative and then 100% of crit damage additive. I’m not exacty sure, how the math works here but i would assume for example: if bleed damge is 30000 the damage should be ((30000 * 1,7+30000 *12 (crit dmg 1200%) * (damage multiplier of main atttribute).
That should not be billions of damage but at least some millions, which over the duraion should be several hundredthousend of damage / s.
Right?
That should be in 40% of cases (my crit chance) the case for every time i inflict bleed damage.
As extra damagei.
But i cant in median get over 200,000 dotdamage. For some rare secs it reaches 600k but like i wrote in median 200k. That is not enough for a smooth gameplay.
And it seems, that even with constant rend spamming and the andys procs and the overpower procs (rupture+overpower glyph), the dot damage is not really stacking.
Edit: got the ring and the other uniques for the barb and hmmmm. The damage is not really incresing. Even with the 2 stacks from brawling skills. Maybe if kick as core skill had no cooldown like touch of death. But yeah, so it is not really working.
Try Locran’s amulet.
Stack enough vuln to hit 45% on Hemmorhage, then stack crit everywhere else. A big issue you’ll run into is that Grandfather is BiS for maximizing crit damage and Gushing Wounds, so Shattered Vow is gimping you there.
Locran’s and Grandfather with maxed Hemmorhage, maxed Blood Rage, and Flay Duration are your best bets. You’ll have to use Shard of Varathiel, Adaptability, and Moonrise to max your bleeds with all the other things I’ve mentioned. Applying Rend stacks from Ravenous with Leap, and using Rumble and the EQ runeword to get keep 5 quakes up.
This means you need mad leap cdr and a good way to proc eqs with the runeword. Shako would be better than Andy’s.
So much maintenance and high requirements.
Thx and i see the reasons for the items and the skills, but i think, i will bury my idea with bleed and shattered vow/andy at this moment.
A bleed build without spamming rend and rupture and some shouts doesn’t feel right for me. 
If Wanton Rupture would be below 5 second cooldown, this Mythic would be amazing.
I’d put Rupture in there for AOE and attack speed.
You don’t have to use Leap and Ravenous for a good Flay build. It’s just not what it was 2 seasons ago, and Shattered conflicts with maximizing crit.
I’d at least try crit tempers and Locran’s before you toss the build completely. Are Hemmorhage and Blood Rage maxed out? You can still use Rumble with runeword eqs to get the 50x.
Rend is trash compared to Flay. Very hard to make it work.
