Eldrun Conjurer
The Eldrun set is in a kind of weird design space in my opinion since it turns Occultist's Summon Familiar into a player scaled pet. So my thought was: why don't we triple down on those?
Presenting: The Eldrun Lightning Pet (but not really) Conjurer
https://www.grimtools.com/calc/ZDML5WWN
Archetype: Lightning Caster with a bunch of player scaled pets
Main Damage Skill: Storm Totem
Auxiliary Damage Skills: Wind Devil (4 of them), Summon Familiar (2 of them)
Resistance Reductions:
Curse of Frailty-Vulnerability (-26% Elemental)
Wind Devil Raging Tempest (-37%/-38% Elemental, depending on the Relic completion bonus roll)
Arcane Bomb devotion proc (-35% Lightning) linked to Curse of Frailty
Elemental Storm devotion proc (-32 Elemental) linked to Wind Devil
Hand of Ultos devotion Proc (20% reduced Elemental over 2 seconds) linked to Storm Totem
The idea behind the build is that we drop 5 totems at once (+4 Summons and +2 to max totems does that) and kite enemies while our 11 player scaled pets do their thing and we keep on applying Curse of Frailty to keep the crit chance high-adjacent and the enemy res low for the 5 totems to shotgun the hell out of your enemies
Admittedly the build feels a little squishy at times while pushing SR and farming SR 30-31 (though I'm coming off of a Worldkeeper acid Conjurer and Dawnkeeper Retaliation Warder which both are very tanky builds and the only other ones I've pushed into this "endgame" to date) but if you know how to interact with different Nemesis mechanics it's not all that critical and the damage output is solid while the playstyle is very different compared to most other builds
