It seems like every Borderlands 4 boss can drop some game-changing gear, but Rocken Roller is one of the best bosses to farm for any build. Rocken Roller is a challenging fight, and it's worth the effort since you can walk away with some of the best items in Borderlands 4.
Rocken Roller is an Auger Mine boss, so you'll need to make some progress in the main story before you can reach it. It's also located in a high-level area, discouraging new Vault Hunters from farming even further. Once you have a decent build going, however, you can steamroll Rocken Roller until it drops what you need. Here's how you can farm Rocken Roller in Borderlands 4 and get all its legendary drops.
How to Farm Legendaries in Borderlands 4
Legendary items are extremely valuable in Borderlands 4, and if you're having trouble getting some, try these spots out.
How to Find and Beat Rocken Roller in Borderlands 4
Rocken Roller is located at the end of Trinket Crevass, an Auger Mine in the Ruined Sumplands region of Carcadia Burn. To reach it, fast travel to any safehouse in Carcadia Burn, and then head to the northwestern edge of the map. The entrance to Trinket Crevass is near the ocean.
Auger Mines are unlocked after completing the Shadow of the Mountain main quest in Terminus Range.
Trinket Crevass is infested with Pangolins, armored enemies that can ball up and give themselves armor when they're near death. Bring a corrosive weapon to melt away their armor and a fire weapon to deal with their regular health bars. After a few Pangolin encounters, you'll reach a checkpoint with a vending machine outside of Rocken Roller's arena.
Rocken Roller is covered with Vile crystals, preventing you from damaging it until they're shattered. Focus on the glowing crystals attached to its body, then use a fire weapon to maximize your damage output against its red health bar. Repeat until the boss goes down to complete the Auger Mine.
Rocken Roller Legendary Drops
Rocken Roller can drop two legendary items once defeated in Borderlands 4:
|
Legendary |
Effect |
|---|---|
|
AF1000 (Repkit) |
Time Dilation: Duration increased by 100% and Cooldown Duration decreased by 50%. |
|
San Saba Songbird (Pistol) |
Dueling Pistol: Deals +100% damage for 5s after swapping guns. |
Both of these items are incredibly strong for different reasons. The AF1000 is one of the best Repkits in the entire game, especially if you don't want to micromanage buffs. It heals over time, but it has a greatly increased healing duration and a super short cooldown. It's basically like having permanent health regeneration.
San Saba Songbird, however, is completely broken. It's a Jakobs revolver that deals double damage for a few seconds after you draw it. Paired with crit-boosting perks and items, it can decimate anything you put in front of it. You can even one-shot bosses with the right setup!
Since there are only two legendary items in Rocken Roller's loot pool, you'll have a higher chance of pulling the gear you want. Still, legendary drop rates are low enough in Borderlands 4 that you'll want to bring a ton of cash just in case you need to pay for Moxxi's Big Encore more times than you planned.
