How Reflux Works in Borderlands 3

Reflux is a Hyperion Shotgun. It is very similar to the other weapon called Brainstormer. It is also a Hyperion shotgun, but Reflux is considerably stronger. Brainstormer is locked to the shock element and does okay damage, but reflux is locked to the corrosive element and deals a lot more damage.

Its special ability is that the bullets create corrosive chains between the enemies in the area. With FL4K, for example, you could chain the shots between nearby enemies, and if your Megavore would proc, then you could get your Action Skill Cooldown down in no time.

It has a Biohazard projectile pattern and comes in 2 variants. The first is times 7 and the shots will cost only 1 ammo, and the second is times 14, but the shot cost increases to 2 ammo per shot.  Now let's see the specifications of the weapon, and then I will tell you how to get Reflux in Borderlands 3.

How to Get Reflux in Borderlands 3

In order to get the weapon, you must play on Mayhem Level 6 or above. You want to finish the main mission from the base game: "The Family Jewel".

After completing the mission and defeating GenIVIV, you will be able to return to this map and farm the enemy for the Reflux Shotgun. It is a boss that has mostly armor and shields. You will need to use shock or radiation elements effectively to get rid of the shields, and corrosive or cryo to get through armor and defeat the boss. After doing so, there is an 11.4% chance of getting the Reflux Hyperion Shotgun.

It is a dedicated drop that has a pretty low drop chance, especially if you are looking for a specific anointment. However, on April 8th, in the new patch to Borderlands 3, you will be able to reroll anointments on weapons for the right price [eridium]. It might make farming for the perfect Reflux a lot easier, but you definitely know everything you need on now how to get Reflux in Borderlands 3.

Is Reflux Worth the Effort?


This is one of the best weapons in Borderlands. The shotgun’s special effect makes the gun very good against large groups of enemies. It is a little bit weaker against bigger or isolated opponents and bosses but it is still a decent choice to supplement your build. Every Vault Hunter can make use out of the Reflux Shotgun. Hopefully, after this article, you know exactly how to get Reflux in Borderlands 3.
