Wanted to showcase my Dual Strike of Ambidexterity Berserker in a T16 with 48% more monster life, Deli mirror, and around 3.4k league mechanic juice.
Current PoB: https://pobb.in/vxqhmw3IVoGN (using normal dual strike since new gems aren't in PoB yet)

Doesn't seem like many people are playing/talking about this skill, but I'm overall very happy with my league start. This skill scales damage very easily so single target has never been an issue at any part of my progression.
Basic concept is using a main hand weapon that does double damage (I used Frostbreath + Ichimonji into T16s before switching to Paradoxica). Flat damage comes from Added Lightning Support + Wrath + Smite. This lightning damage is then scaled by Volatility and the Dance With Death keystone from Brutal Restraint.
