For this loadout, I have this equipped: energized neck coil, ahanae crystal, timekeeper's jewel, stone of malevolence, and burden of the destroyer. Since the latest patch 448,817, eruption may be better than miasma with more focus in skill damage compared to status damage and duration. I wouldn't say this is entirely optimal for boss rush because of how annoying long rage bosses can be while using sparkfire and nebula. Right now I am using the build found on the Chaos Gaming farming build video, which makes use of Invoker Way of Kaeula + Archon Havoc Form, cost of betrayal, burden of the sciolist, burden of the destroyer, burden of the gambler, and sapphire dreamstone. Of the 200 hours I have played Remnant 2 this has to be the best and easiest build I have tried.
