Build Overview

This build is centered around the Amon Calamity tree and Hellfire. It plays as a straightforward status hybrid crit setup. Early on you only really need two legendaries Hellfire & Firewerks. But as you climb the Vault Hunter rinks you're going to eventually look for more items to really bring the build together. Overall the build is extremely powerful and all the information you need to build it is down below !

Equipment

Weapons

Repkit & Ordnance

Utilities

On Hellfire we want The biggest magazine that we can find ideally something with a barrel attachment that gives you double barrels or Jacobs but if you can't get either it's fine.

on Complex Root we want Corrosion and shock as the elements on this sniper

on Super Soldier aim for Siphon Tolling and Vagebond Meandering

on Triple Bypass look for Enrage or Elemental Affinity

On your enhancement you're looking for SMG damage, SMG Fire Rate, and SMG magazine or Gun versions of said stats! Any mixture of any of those works!

For mobbing you can pick up Blockbuster & Firewerks But it's not mandatory but it will help with wave clear .

Gameplay

The gameplay is extremely simple and straightforward. All you need to do is simply go in and shoot things with your gun. Whenever you're facing off against a boss, activate your Fulminating Fist. If you're not too bothered to do it, you can swap over to Pyroclast when you're mobbing, but it's not necessarily that important to do so if you don't want to. For the most part, your gun should just shred everything, and your firewerk armor missiles should deal with pretty much anything mob related. Use your Stormcutter to help maintain either cool down or keep the active going during a fight, and besides that, it is a extremely straightforward build.

when going against any form of shielding or corrosion that is too much for your Hellfire swap to Complex Root And nuke everything it can easily kill everything by itself you have tons of gun damage so the sniper is highly effective.
