Not my build! This is working from Ruetoo's build and just where I'm at. Current PoB https://pastebin.com/bBY0ddA3 with about 30 ex investment.

My set up is very unoptimized, considering I have to take multiple nodes for just accuracy. This build is extremely tanky and for people who want to play a very tanky LS Zerker without forking out the cost for Omni and building the gear for it. The one caveat to this build is it is more of an active playstyle which is similar to Omni LS Zerker, you want to make sure your Anger aura is always up pop Berserk for max DPS. During mapping I never feel like I have to use Berserk or even the totem unless I am using sentinel on a huge Expedition pack.

The combination of Transcendence and Loreweave/Leadership's Price ignores the -15% max resist which makes our armour even more effective.

In terms of gearing, thanks to the Tasalio's jewel and Purity of Elements we can pretty much focus on just getting lightning/cold res & chaos res to get overcapped.

For the effective hit pool I set it as 20k for each element except chaos.

PoB settings for this are elusive at 150% even though maximum is 220% for me, but we are not always at maximum. Rage is 30 out of 50 because same thing. I do not have the optimum cluster jewel as you want to replace Haunting Shout with Lead by Example for constant onslaught.

At the time of me building up the gear, the biggest purchases were the double phys taken as ele Watcher's Eye which I got for about 11ex and the two needed jewels for 6ex at the time.

Claw was one I got for 2ex with room to craft ele pen on it, since ele pen is a huge increase to our damage. You don't need triple ele damage on the claw, just two high rolls and good attack speed is better since you don't actually have to do cold damage to get brittle thanks to Leadership's Price.

I highly recommend this build, it is great for bossing, expedition, and one of the faster mappers I've played in a long time. The build has a simple rotation of using Anger at the beginning of the map, Gen's Cry, and then go blast. You only need to pop Anger again every like 20 secs and Gen's Cry whenever you want.
