This build ain’t cheap, its expensive and efficient, I’ve been using this for a few weeks and nothing standing on the wrong side of the barrel survives for very long, works in Steel Path very well and can oneshot acolytes very easily
Against Corpus switch the Bane Mod
Against Infested Switch the bane mod to a [Serration] or a Hunter’s Munitions
Replacements
Primed Bane > Bane or [Serration]
Riven > Hunter’s Munitions or Serration(both work I’ve found much more success with Munitions)
Primed Cryo Rounds > Cryo Rounds or 60/60 cold mod
[Primed Shred] > [Vile Acceleration] or [Shred] (I’ve found [Shred] is better in my own tests)
[Galvanized Chamber] > [Split Chamber]
[Galvanized Scope] > [Critical Delay] or [Point Strike]
[Stabilizer] > Exilus is up to you I just don’t link the initial recoil of firing the [Trumna], [Vigilante Supplies] is a very good alternative
I have used the super budget version of this build with all the cheaper mod options and still found success in SP and Arbitrations but as one can expect the actual build preforms better in longer runs
Tips for Secondary Fire
You’ll get more bounces and therefore more damage if you aim at the ground in front of your desired target, imagine you’re skipping a stone, you want the grenade to bounce into them, not directly at them, this way you’ll get more predictable and accurate secondary fires
