Borderlands 3 is an FPS and an RPG in equal measure, and farming is a crucial part of the experience. The catch is that players will always try to optimise their XP farm, and it just so happens that Borderlands 3 has an offline XP glitch that's still working.
There's no way of telling when will Gearbox fix this Borderlands 3 offline XP glitch, but we thought you, too, might make good use of this technique in the meantime. Find all the necessary steps for this XP farming method below, and good luck.
Borderlands 3 Offline XP Glitch
What you want to do for this XP farm to work is disconnect your Internet at just the right time, after killing the boss you'd like to farm in the first place. It's important to mention that this method is only available to players who have already completed the story, as it requires Mayhem Mode. After reconnectign online, you will notice that your Mayhem counter has exploded to a significant 900% increase in XP, Cash, and Eridium drops.
That's all there is to it, according to our sources. Do keep in mind that this very well could get disabled with the next hotfix, but there's been no official confirmation of that just yet. Enjoy it while it works, we suppose.
You might also be intrigued by the prospect of upgrading low-level weapons you liked early in the game. You may be disappointed if that's the case.
