I saw someone doing something similar on ninja (user: mlodysfider_goat_hooves) so I thought I'd try it out. It's a high budget, boutique? build.

Cool things about the build:

Omni/Heatshiver to scale Herald of Ice + Oriaths End

Annihilating Light - 3x dmg for everything elemental

Abberaths Hooves for autobombing (linked to 4 support gems including added lightning which surprisingly shocks pinnacle bosses for a bit)

4L Herald of Ice socketed in +3.5% crit chance gloves

Phase run to move fast

Progenesis + bloodnotch tech + utulas hunger for tankiness

Oriath's End + Herald of Ice + 8% explode from tattoos for clear

Hydrosphere + Vortex functioning as a 5L, from my testing its way more dmg than using either skill with another dmg link

One Step Ahead Forbidden jewels for +8% action speed, can be replaced for whatever, I just like move speed

It's not the greatest or fastest mapper, more of a concept build to have big explosions. That being said, it's surprisingly tanky with the Bloodnotch tech, and playing conservatively I don't die very often. POB: https://pobb.in/LxsyUa-yWWEA
