Since there is probably like no one playing this i just to want to leave this here in case anyone is interested in an off meta build:

This is no overly optimized Build but just my own Character I played in the Archnemesis League. In that league i completed 36 Challenges with it. After that i took a break for the last league.

It currently makes use of petrified blood for the overleech and for life regeneration to have a bigger impact as well as to increase the damage through pain attunement on Skin of the Lords to save the passive tree points. Being Chieftain and utilizing the Melding Flesh Jewel while running Purity of Fire requires all gear to pretty much only need Cold and Lightning Res, making room for other suffixes like Chaos res.

Damage-wise the goal is to just increase the Gem level of Tornado as much as possible to scale it's damage and to make it faster for a decent feeling of the skill. With scaling physical skill gems Holy Flame Totems make a nice addition for mapping as well as bossing as they shoot projectiles hence feeding the Tornado in it's initial state with some extra damage (and make it much more visually appealing :D)

The 3.19 changes to Melding of the Flesh having -4--6% to all Maximum Elemental Resistances now might have killed the use of rf for even more damage though. It isn't used all the time, but having the option to activate extra damage was nice in some cases. It also lost Zealotry due to the removal of the aura mastery, so i already replaced it with Herald of Purity for the time being.

It was quiet good for what it is, as it isn't really that expensive. It is utilizing mostly niche items aside from maybe the Ashes amulet. So it might make an okayish league starter but i can't guarantee this.

I would appreciate any input to spice this build up a bit.
