Hi everyone, wanted to share a build I cooked up. This is a dual strike of ambidexterity endurance charge stacker. I've reached 30M pob dps with what I think is a pretty modest config. I pretty regularly get better shocks than I have in the file. Anyways here's how it works:

grab as many endurance charges as you can
Watch poe trade all day for a hard to find precursor's emblem to appear
Deal a ton of damage
Get enough defense to not explode when elemental damage touches you because you use replica abyssus

The Precursor's emblem is doing the heavy lifting in this build. In case you're unfamiliar with the ring it gets 3 mods vary between power, frenzy and endurance charge modifiers. The mod we're after adds flat fire damage per endurance charge. We can actually get 2 of this mod on the same ring to double the flat fire damage. Then we use kalandra's touch to mirror it since these rings are hard to get. Ultimately, with 10 endurance charges were getting 320-640 added fire damage just from our ring slots. We pair this crazy flat damage with paradoxica for double damage and an off hard claw for crazy attack speed.

The total bonus we gain from our 10 endurance charges is:

• 50% Increased Armour
• 50% Increased Stun duration
• 30% increase AoE (useless for us)
• 110% Increased damage
• 320-640 added fire damage
• 120% increased critical strike chance
• 40% physical damage reduction
• 40% elemental damage reduction
• 100% reduced extra damage from critical strikes against us
• 2% life regen

10 endurance charges brings this build from 9M to 30M dps

For mapping we have increased additional strike range from the ascendency and annoiting Sione's so this build hardly plays like melee, I'm basically hitting the whole screen, which makes it feel really smooth and gives some safety in boss fights. Speaking of boss fights, with the exception of the tincture we have really consistent dps uptime.

Note on defenses: this is definitely not a hardcore build, but with some adjustments it could be, dropping the replica abyssus and stacking max res could make it a lot tankier, but it would probably half the dps.

Here is what I've done on the build:
All pinnacle bosses
Uber shaper
T17 full clear with bosses on Citadel and Fortress
Feared 70+ quant farming

Overall cost probably in the 50 div range + the cost of the ring of which there are none for sale online at the time of writing this. You could get a single mod ring (10-16 added fire) which I was doing for a while and get plenty out of the build
