InWarframe, we travel through the Sol System as one of the Tenno, survivors of an interdimensional incident that can now wield psychic powers that allow them to fight through space through their Warframes. However, those are not the only weapons you will find in the game, and in a space as vast as this, your arsenal will always grow.
One of the many weapons you may obtain in the game is the Quellor, an assault rifle that comes as a relic from the Old War. Used by the Dax soldiers during Railjack missions, this rifle can annihilate any enemies with ease, and we’ll tell you why.

What Is The Quellor?
The Quellor is an assault rifle issued to Dax Railjack soldiers during the Old War. This rifle hasa Primary Fire mode with fully automatic shots that deal Puncture-type damage, whilethe Alternate Fire mode shoots a single charged, Cold-infused projectile.
To be able to use the Quellor,you must reach at least Mastery Rank 12 and have played the Rising Tide Questto be able to host missions in your Railjack.

You can, however, join other players' Empyrean missions once you have finished The Archwing Quest.
How To Get The Quellor
To get the Quellor, you must obtain the blueprint from defeating the following captains in Empyrean missions:
7.31%

Lektro Commander
Pyr Captain
Once the blueprint drops, you must build the Quellor following the next crafting recipe in your Orbiter Foundry:
Tellurium x4
Rubedo x6,250
Circuits x3,600
Alloy Plate x15,350
Best Quellor Builds
What makes the Quellor shine is its high Magazine and Maximum Ammo, a high Status Chance, and on its alternate fire, a great Crit Chance as well. However, it would be best to keep in mind that the Primary Fire mode does not share that same percentage of Crit Chance, and it also has a very low Reload Speed, so you must mitigate its low points when making a Quellor build.
Malignant Force
On the Arcane side, and given the Magazine size of the Quellor, Plated Round makes sense the most, as it will easily improve the damage of this rifle. However, no Exilus mod is needed here.
On the Mods side, Primed Fast Hands helps a lot with the low reload speed, which the Quellor sorely needs. With such a high Status Chance, Hunter Munitions and Galvanized Aptitude shine great here, and Malignant Force supports this and turns the Cold Damage into Viral Damage, which works great against Orokin enemies.
While the normal fire mode doesn’t boast a good Crit Chance, Galvanized Scope and Vital Sense work amazing while you’re using the Alternate Fire mode, and finally, Galvanized Chamber adds a useful Multishot boost.
