What to know
- Triple Bypass is a legendary repkit in Borderlands 4.
- You unlock the ability to farm it only after you’ve reached the Terminus Range and completed “Shadow of the Mountain,” which opens up access to all the Auger Mines.
- It drops from The Backhive boss, located in an Auger Mine area called The Claim, which is inside Zandra’s Hideout near the Fadefields.
- Its special effect is called Heart Pump: it has three charges, and each kill has a 30% chance to replenish one charge.
The Triple Bypass repkit (or repair kit) is one of the more sought-after legendary repkits in Borderlands 4. If you’re trying to build up survivability or improve your resilience in difficult content, this repkit is especially useful because of its charging mechanic and strong heal. But getting it requires meeting certain prerequisites and defeating a mini-dungeon boss.
BL4 Triple Bypass location: Where to farm it
The Backhive boss is exclusive to The Claim, an Abandoned Auger Mine in the Dissected Plateau zone known as Fadefields. To reach this area and take on The Backhive, players must first progress far enough in the main story, completing the "Shadow of the Mountain" mission. This unlocks access to all Auger Mines, including The Claim.
BL4 Triple Bypass farming requirements
To farm Triple Bypass, you need:
| Prerequisite | Details |
|---|---|
| Reach Terminus Range | The region of the map you must unlock. |
| Complete Shadow of the Mountain mission | This unlocks all the Auger Mines. |
| Access to The Claim Auger Mine (inside Zandra’s Hideout) | The area where the Backhive boss is located. |
How to get Triple Bypass in BL4 [Step-by-step guide]
Here’s a detailed guide to getting Triple Bypass:
Step 1
Make sure you’ve progressed through the main story until after Shadow of the Mountain and that Terminus Range is unlocked. Without this, you cannot access the Auger Mines needed.
Step 2
Fast travel to Zandra’s Backup Plan in the Fadefields region.
Step 3
Open the map, locate The Claim (one of the Auger Mines) near Zandra’s Hideout. Set a ping or marker for The Claim so you know where to go.
Step 4
At Zandra’s Hideout, find the wall or barrier that leads into The Claim dungeon. There’s a passage through a wall at a dead end near Zandra’s Hideout that leads into The Claim.
Step 5
Enter The Claim. It’s a mini-dungeon with environmental hazards (poisonous water) and fights along the way.
Step 6
Proceed to the end of The Claim and defeat The Backhive boss.
Step 7
After vanquishing The Backhive, loot the chest afterwards. There's also a return point (via a grapple point) that allows you to exit and come back to farm the boss again if needed.
Step 8
Repeat as needed until Triple Bypass drops. Because of RNG, this might take several runs. Bring good gear and builds to make the fight efficient.
Boss fight: The Backhive
Here are the important details for the boss fight:
Attack Tactics
The Backhive has several attacks, including stomping (which sends out shockwaves), charging at you, and periodically spawning Kratch on its back, which fight you.
Avoid Waters
The arena has poisonous water in certain chambers; avoid staying in these areas as they deal environmental damage.
Best strategies
Long-range Ignite damage builds work well. Characters that can summon minions (or have pet/specter-like helpers) help control the Kratch while you focus on The Backhive.
How Triple Bypass is useful in BL4
Triple Bypass has several benefits:
| Feature | Effect / Why it helps |
|---|---|
| Legendary repkit rarity | Makes it more powerful than common or rare repkits; good for high-difficulty content. |
| Heart Pump effect | You have three charges, and each kill gives a 30% chance to recharge one charge. That means in fights with many enemies you can regenerate charges fairly often. |
| Long heal timer and amount | At level 50 it heals a large amount (with part of the healing over time). Useful for surviving burst damage or prolonged encounters. |
| Resurgence / farming potential | Because you can replay the boss and area, you can farm it to get better rolls or in case you don't get the desired stats or effects first time. |
Triple Bypass Repkit helps you when the going gets tough in BL4
Triple Bypass is one of those items in Borderlands 4 that rewards both patience and preparation. You’ll need to unlock the right area (Terminus Range, complete Shadow of the Mountain), go into The Claim Auger Mine, beat The Backhive, and then hope it drops. But when you get it, its recharge mechanics and healing power make it a strong choice for tougher content. If you build around its strengths (lots of enemies, Ignite or sustained damage, avoiding environmental hazards), it can really save your skin.
