Borderlands 4 features some returning weapons, and the Plasma Coil is one of those. It’s a legendary SMG that shoots elemental bursts. Being a Maliwan weapon, it can switch between one of two element options, so finding the one you require for a build can take some time. Moreover, it is something that you can only acquire at the end of the campaign.
The gun deals a significant amount of damage by itself and synergizes well with a lot of element-based builds. This guide will show you where to farm the Plasma Coil legendary SMG in Borderlands 4.
How to farm Plasma Coil in Borderlands 4

The Plasma Coil legendary SMG is a boss drop, meaning you can target farm the item in-game. However, you will need to complete the story campaign. The gun drops as one of the rewards for defeating the Timekeeper within the Upper Dominion.
To reach the arena, follow the ‘Timekeeper’s Order’ main quest. Reaching the boss isn’t enough, as you need to do it twice. The first one is his regular form, after which you’ll fight the Guardian Timekeeper. During the fight, you’ll face various AoE attacks, including the one where the boss will turn the entire arena into Shocked ground.

Use the grapple to climb onto temporary platforms in the air and avoid damage. If you’ve completed the campaign and defeated the boss, you may need to fight him again a few times, as the Plasma Coil isn’t a guaranteed drop.
Use Moxxi’s Big Encore to repeat the boss fight until you get the gun. Additionally, don’t forget to open the four red chests, as they also have a chance to drop the weapon you’re looking for.
