this is a 0 forma [Khora] build that i use for steel essence farming and other resources in the steel path (SOLO). just do long survival missions and find a space deploy your 4th ability and spam 1.
arcane energize is mandatory sorry, and arcane [Fury] is a personal preference.
the vinari build can be any thing
for more loot try to bring 1 or 2 nekros in your party
https://overframe.gg/build/75388/ - this is the build for the stat stick that i use
ALSO a [Smeeta Kavat] with only the [Charm] mod on will really help you.
