Borderlands 3Going Rogue

"Going Rogue" is the 15th Main Story Mission and is unlocked when you complete "The Family Jewel".

The Rogue Sight Pistol is bound to the "Going Rogue" quest. It scales with your level, but disappears after the quest is turned in.

The good news: Clay already found the next Vault Key fragment. The bad news: he subcontracted the work to another smuggling crew and now he can’t get a hold of them. Looks like you’ll have to track them down if you want that fragment.
