This [Limbo] build is primarily built for finding Syndicate medallions, Voidplumes, hidden resource caches and Ayatan sculptures.
With a good companion and an eye on your mini map you'll be snooting up the loot faster that Tony Montana.
Cast his 4 to break all the containers around you in a large radius, collect the loot, look for loot containers on the map that didn't get sucked up by your companion's [Vacuum] ability.
For companion I use [Oxylus] for the plant scanning, [Animal Instinct] and [Vacuum] mods.
I put Gauss' 3rd ability on for large area room clearing since this is NOT a steel path build it should only take 1-2 casts to clear all enemies. Hold for heat, press for cold and together you get blast damage.
Stasis and Rift surge are never used, feel free to find a use for them yourself. If shields go down, jump into the void and get out of there.
