What to know
- There are 8 confirmed legendary Repkits in Borderlands 4.
- Each one drops from a specific boss or area, tied to a named mission or location.
- Repkits grant healing and unique perks like cooldown reduction, elemental immunity, or charge replenishment.
- Farming them requires targeting their associated bosses or regions.
In Borderlands 4, Repkits are a new type of gear that act as advanced healing modules with extra perks.
Unlike regular health kits, Repkits don’t just restore HP — they add unique survival mechanics that can completely change how you play. Think of them as a hybrid between healing items and modifiers: they keep you alive, but also grant buffs or situational bonuses.
What makes Repkits special in Borderlands 4
Cooldown-based use
Instead of being consumables you pick up, Repkits have charges or cooldowns you can trigger during combat.
Legendary variants
Legendary Repkits add powerful effects like elemental immunity, charge replenishment on kills, or turning excess damage into healing orbs.
Synergy with builds
The right Repkit can complement your skill tree or weapon setup — for example, War Paint boosts speed and fire rate, perfect for aggressive builds.
Dropped like loot
You get them the same way you’d farm for legendary guns or shields — by targeting bosses, missions, or red chests.
So essentially, Repkits are Borderlands 4’s way of making healing gear just as build-defining and farm-worthy as legendary guns or shields.
All legendary Repkits in Borderlands 4
Adrenaline Pump
Dropped by Radix during the Vault Fragments mission in the Arch of Radix (Carcadia Burn). This Repkit automatically restores your HP whenever you trigger a Second Wind, making it a great safety net in tough fights.

AF1000
Found from Rocken Roller in the Auger Mine, Trinket Crevass area of Carcadia Burn. Its perk doubles duration but halves cooldown, giving you more uptime on healing effects.

Blood Analyzer
Dropped by The Oppressor in A Lot to Process on The Killing Floors (Fadefields). When used, it grants immunity to the last type of elemental damage taken for 7 seconds—perfect against bosses with mixed elemental attacks.

Defibrillator
Drops from Core Observer in the Order Bunker mission at Blacklime Bunker (Fadefields). If you’re below 20% HP, there’s a 50% chance it will replenish a Repkit charge, keeping you alive in critical moments.

Kill Spring
Obtained from Axemaul in the Auger Mine (Carcadia District). It converts excess damage from kills into healing orbs that track and restore allies, making it a must-have for co-op runs.

Pacemaker
Dropped by Horace in Down and Outbound at Horace’s Oversight (Fadefields). It passively regenerates HP, with faster recovery when you’re low on health—excellent for sustained fights.

Triple Bypass
Farmed from Backhive in the Auger Mine’s Claim area (Fadefields). This Repkit has 3 charges and a 30% chance to replenish one whenever you score a kill, rewarding aggressive play.

War Paint
Dropped by Saddleback at the Ripper Drill Site in Old Scrape (Terminus Range). It boosts fire rate and movement speed by 30% for 15 seconds, with a cooldown reduction when you take damage. It’s ideal for fast, aggressive builds.

How to farm legendary Repkits
Step 1
Pick the Repkit you want and identify its boss and mission (e.g., War Paint → Saddleback at Old Scrape).
Step 2
Travel to the listed location in the right region. For some (like Auger Mine), prepare for heavy resistance.
Step 3
Defeat the boss and check drops. Legendary Repkits aren’t guaranteed, so expect multiple runs.
Step 4
Use luck-boosting modifiers or farm in co-op for better chances.
Step 5
Once acquired, experiment with the Repkit’s unique perk to see how it fits your build.
Why legendary Repkits matter
Unlike standard healing kits, these add build-defining perks. For example, Pacemaker is great for sustain-focused builds, while War Paint gives a speed and DPS boost perfect for aggressive players. The right Repkit can be the difference between surviving UVH2 and wiping on a boss run.
Final thoughts on Repkits
Legendary Repkits in Borderlands 4 aren’t just backup heals — they’re tactical tools that can define your survivability and playstyle. Whether you want elemental immunity, ally-healing orbs, or passive regen, farming the right one pays off.
