A recent update to how Arbitrations work in Warframe has seen Archgun Riven Mods being added to the game. Rivens are randomly generated mods that can offer significant bonuses to a weapon. They can increase a number of stats for the gun and can be rerolled using Kuva to get the best stats for that particular weapon. In this guide, I will show you how to get an Archgun Riven Mod.
How To Get An Archgun Riven Mod
Unlike other Rivens, which can only be earned from Sorties, you can specifically farm for an Archgun Riven Mod. By doing Arbitrations, you can obtain one Vitus Essence for each Rotation completed. You can then use these Vitus Essence to purchase things from the Arbiters of Hexis on any relay. One of the items that you can buy is an Archgun Riven Mod at the cost of 25 Vitus Essence.
All you have to do is visit the Arbiters of Hexis on any relay, and interact with the NPC on the left-hand side, just inside the door. Scroll to the bottom of the available rewards, and you will see the Archgun Riven.
How To Access Arbitrations
To get access to Arbitration Alerts, you need to complete every node on the star chart. This means completing each mission, on each planet, at least once. If you want to check which missions you have yet to complete, you can visit the Arbiters of Hexis on any of the relays. Just go to their Syndicate room and talk to the NPC on the left-hand side of the entrance. If you still have missions to complete, the NPC will tell you which ones they are.
If you are new to the game, there is no rush to get access to Arbitration Alerts. They will more than likely be too difficult for you to complete. Focus on ranking up, acquiring weapons and mods, and learning how to put together good builds instead.
Now you know how to get your hands on an Archgun Riven Mod. It is interesting that they have been added to the game now, they may be offering some hint of the new challenge that will face us when the Railjack expansion is launched. Best of luck, Tenno!
