Starting Location: Raiders of the Lost Rock
Talk to Miles Brown
Claptrap has another mission from his job list for you – we need to head to Eden-6, Floodmoor Basin to the Reliance camp. There you can talk to the guy who posted the job. He stands next to the ammo dump / meds vending machines.
He says some jabbers stole his rocks. We must head to Ambermire to track the thief. Quickest way is to teleport over there, but you can also enter the Ambermire through Floodmoor Basin. Pick up the rock on the floor at the Ambermire entrance.
Go from one waypoint to the next, picking up each of the same-looking rocks along the path.
At the end of the rock trail, a door opens and some jabbers spawn. Kill them.
Collect Brownrocks 0/4
Enter the area where the Jabbers spawned. This also counts as a named location that is not available without this quest.
Kill King Gnasher
A type of miniboss spawns – a larger version of Jabber. Some small Jabbers also spawn along with him. Headshots are their weakspot. Clear the small jabbers out first, then focus fire on the big one.
Pick up the rock that the King Gnasher drops. Miles named this rock Abigail, it’s his favorite rock.
Return to Miles Brown
Return to the job giver in Floodmoor Basin. Give him his rocks. A rock collector made happy and you earn the unique grenade mod “Porcelain Pipe Bomb”.
Special Note: In the unpatched version 1.00 of Borderlands 3, the Porcelain Pipe Bomb instant-kills all enemies in one hit regardless of their level or health. This is somewhat game-breaking and can be exploited against bosses to boost XP. However, it only works if you have the disc and stay offline so it doesn’t download the latest patch and can’t download the hotfix. When you boot up the game while connected to the internet it will automatically download a small hotfix (then even if your game is version 1.00 the grenade exploit is fixed). If you’re playing completely offline from the beginning of the story you can use this grenade exploit.
This finishes Raiders of the Lost Rock side mission in Borderlands 3.
