You all know the quest “Guardian Hunter” and how to farm exp, gold and moonstone with it.
But you didn’t know that you can do anything you want in teh meantime when playing as Jack.
Use the Merger-Glitch --> causes your wristlasers to be on forever, point them at the Guardians that spawn…
used this with my brother to get our 3rd alts up to 60. just remember to make sure your system doesn’t auto shut-off after a certain time! and if you have a system prone to crashing you can have your buddy run around save points every 20 min or so to keep your progress safe.
