This build is the ultimate gas setup for a sniper rifle. Sniper rifles are great for gas procs as they usually hit for large numbers which subsequently make the proc actually pretty ok, unlike a full auto primary such as the [Baza]. With this build guide you'll be killing groups of enemies with a single shot and any others that walk through the lingering proc, even way into lvl 200+.

My goal was to get the most out of the gas procs and that's why I chose the [Vectis Prime] as my go to sniper for the occasion. The [Vectis Prime] has a couple of pros going for it with the larger number of multiplicative damage mods it has, such as [Primed Chamber]. These multiplicative damage mods all boost the [Vectis Prime]'s damage to the highest compared to any other sniper, which subsequently makes the gas procs that much stronger, something other builds aren't able to do.

On top of the mods, the [Vectis] itself is granted some secondary bonus's including the headshot bonus and the combo multiplier, which will be huge benefits in higher level endurance!

Now the hardest enemies by far to be affected would be grineer, of course, due to their armor double dipping onto our gas procs. So to mitigate this, we can either go for armor stripping or just ignore the armor and go for headshots with huge numbers, your choice really. That is where my favorite warframe and probably the best for the latter option comes into play, [Ivara]!

[Ivara]'s cloak and wire augment provides huge damage bonuses to boost the areas we lack in mod space. On top of [Ivara], the helminth system can be used to further buff our gas procs with abilities like Roar or armor stripping with e [Ash]'s shuriken augment.

Without buffs you'll end up getting 1million+ damage headshots and with buffs you'll end up getting 20million+ damage headshots with gas procs dealing 6million+ damage each tick. To assist with this build I usually run Corrosive damage and/or Viral damage on my melee/pet and then [Energizing Shot] on my secondary, to help with long periods of time you'll be sitting on [Ivara]'s wire.

A riven like this will go for ~900 plat and [Primed Chamber] will go for ~800 plat.
