Borderlands3 (PC Only) how to farm "the pearl of ineffable knowledge"

Hello guys, In this video I show how to farm this item, note I¬ the finder of this trick but I hope its useful :) the same method can be used to dupe items by backing up the save file with your item in your inventory which you wanted to dupe and then you can repeat the steps of putting it on your bank and restoring the save.
