Okay, I’m gonna tell you to get the Bee shield, the most broken shield in the whole game. Good news, if you’re up to farm, it’s easy to get. Bad news, you’re gonna have to touch the Tiny Tina dlc, which has major spoilers. What you do is go through the campaign until you get to the forest, and farm the treants. Eventually you’ll get a shield that adds a flat out damage bonus to each projectile fired by your guns, it’s amazing but broken as hell. It’s the only way I could complete UVHM.
