Choosing a Repkit for your build
The listed effects point to different uses rather than a single best choice. Consider whether you need recurring recovery, emergency healing, a response to elemental damage, or a boost that helps you deal damage or move faster.
#1 Best Overall
- Repeat or passive sustain: Pacemaker restores HP over time, with a faster rate at low HP. Triple Bypass offers three charges and a chance to regain one on a kill. Blood Moon instead bases healing on recent damage taken.
- Recovery tied to combat events: Adrenaline Pump triggers on Second Wind, Defibrillator can replenish a charge below 20% HP, and Vitae heals on critical damage dealt.
- Elemental defense or retaliation: Blood Analyzer grants brief immunity to the last elemental damage type you took; Geiger-Roid turns expiring stacks into elemental novas.
- Team support: Kill Spring sends healing orbs toward allies, while Healthraiser spawns Health Boosters at the beginning and end of its duration.
- Offense and movement: War Paint increases fire rate and movement speed; Hugger damages nearby enemies and reflects bullets while active; Outburst adds damage and healing when Torgue Stickies are used.
- Ammo and duration utility: Oxidation returns ammo in proportion to the health restored, while AF1000 offers increased duration and reduced cooldown.
These comparisons describe the reported mechanics, not a ranking: Mobalytics’ September 12, 2026 catalogue does not establish which Repkit performs best across builds or activities.
How to farm AF1000
- Discover Ruined Sumplands in Carcadia Burn and travel to its central Fast Travel Station.
- Go to Trinket Crevass, the nearby abandoned Auger Mine, and defeat Rocken Roller.
- Use the nearby Encore Machine to reset the fight, then repeat the encounter until AF1000 drops.
Mobalytics lists AF1000’s effect as +100% duration and -50% cooldown. See its AF1000 guide for the route.
Rank #2
- Out-of-This-World Adventure – Stranded on a lunar space station, Hugh encounters Diana, a mysterious android resembling a young girl. While searching for a way back to Earth, they fight to survive against Bots directed to “neutralize” intruders.
- Hack & Shoot – Use each character’s distinct abilities to take down enemies. In combat, Diana can hack foes to expose weaknesses so Hugh can blast them with weapons. This unique fusion of gameplay offers an action-packed experience like no other.
- Space Exploration – Teamwork also extends to traversing the station. Utilize the thrusters in Hugh’s futuristic suit to dash and hover around while Diana hacks security systems to solve puzzles. Only together can they overcome all obstacles.
- Collect and Customize – Gather materials while exploring the station to unlock upgrades, build out a diverse arsenal of weapons, obtain new outfits, and more. Once you’re ready, use the new gear in battle and take on even greater challenges!
How to farm Triple Bypass
- Progress the campaign into Terminus Range and complete Shadow of the Mountain to access abandoned Auger mines.
- Travel to The Claim abandoned Auger mine in the Dissected Plateau, Fadefields. The Backhive is beside Zadra’s hideout.
- Defeat Backhive. Use the Moxxi Big Encore machine to respawn the boss and repeat the fight.
PC Gamer’s guide identifies this route and reports that Triple Bypass has three charges with a 30% chance to recover a charge on a kill. The Mobalytics catalogue lists the same location and mechanics. See PC Gamer’s Triple Bypass guide.
How to farm Kill Spring
- Unlock Dominion by completing the main missions in Fadefields, Terminus Range, and Carcadia Burn.
- Go to the Toil of Spoiling Vis mine in the center of Dominion’s Carcadia District, near The Lockaway safehouse.
- Fight through the mine and defeat Axemaul at its end. Repeat the boss encounter if needed to pursue the drop.
PC Gamer describes Kill Spring’s effect as converting 100% of excess damage on kills into healing orbs that seek allies. Its route is detailed in PC Gamer’s Kill Spring guide.

Kill Spring orb behavior and patch notes
Borderlands Support’s October 23, 2025 update notes say that healing orbs spawned by Legendary Repkit Kill Spring can no longer heal enemies. The notes were published October 14, 2025, and updated July 2, 2026. This documents a correction to orb behavior; it does not establish that every Repkit entry or drop route in Mobalytics’ September 12, 2026 catalogue remains unchanged in later patches. See the official update notes.
