Borderlands 4 is full of bosses that test your skills while offering powerful loot, and Mimicron is one of the most memorable encounters early in the game. Located deep inside the Fadefields, this Order bot delivers a fight that demands awareness, elemental strategy, and quick decision-making. On the plus side, it also drops three excellent Legendaries worth farming.
Where to Find Mimicron
Mimicron is housed inside the Tipping Point Order Bunker, found in the southeast corner of Idolator’s Noose in the Fadefields. The front door is sealed when you first arrive, forcing you to solve a short environmental puzzle before gaining access.
How to Open the Bunker in Borderlands 4
- Locate the Fan Shaft – Stand with your back to the bunker’s locked entrance and head right. You’ll spot a massive ventilation fan. Enter it.
- Climb to the Canister – Inside, turn right again to find a ladder. Climb up to reach the Locust station holding an explosive canister.
- Blast Open the Door – Drop through the nearby hole, face the sealed bunker door, and throw the Locust canister to break it open.
- Power the Consoles – Deeper inside, you’ll encounter locked doors. Insert power capsules into nearby consoles and hit switches to keep moving forward.
- Scale the Elevator Shaft – Eventually, you’ll find a seemingly dead elevator. Instead of stepping inside, mantle up the walls to reach the top level. This path leads straight to Mimicron’s arena.
Boss Fight Overview
Mimicron is an Order bot with a simple but tricky gimmick:
- Invisibility: It turns invisible whenever it isn’t actively attacking.
- Melee Rushdowns: It lunges forward with spear strikes and leap attacks.
- Clones: Mimicron periodically spawns shielded copies, forcing you to split attention.
These mechanics make the fight feel chaotic, but with the right elemental loadout, you can cut through its defenses efficiently.
How to Beat Mimicron in Borderlands 4
- Use Shock First – Mimicron opens with a large Shield bar. Shock damage tears through it quickly.
- Switch to Corrosive or Cryo – Once the armor bar appears, swap to Corrosive for steady damage or Cryo if you want to slow its movements.
- Target the Head – Like most bots, Mimicron’s head is a weak point. Focus fire here whenever possible.
- Deal with Clones Immediately – The duplicates carry shield bars of their own. Clear them fast to avoid being overwhelmed.
- Avoid the Leap Attack – When Mimicron crouches, prepare to dash sideways. Timing a dodge prevents heavy damage.
- Use Explosives and Elementals – Grenades and damage-over-time effects help track Mimicron’s location when it vanishes.
The arena has decent cover, so move strategically to keep visibility on both Mimicron and its clones.
Legendary Drops
Defeating Mimicron gives you a chance at three dedicated Legendary rewards:
| Item | Type | Effect |
|---|---|---|
| Luty Madlad | SMG | Overheats rapidly but cools just as quickly, enabling near-constant fire. |
| Complex Root | Sniper Rifle | Fires a shot that spawns diverging fractal projectiles, ideal for mobbing or hitting large targets multiple times. |
| UAV | Grenade | Deploys a homing drone that rains explosives from above. |
These Legendaries cover different playstyles: Complex Root for precision mob control, Luty Madlad for close-quarters shredding, and UAV for area denial.
How to Farm Mimicron for Legendaries
Once defeated, the bunker becomes a repeatable farm spot:
- A purple orb spawns in the arena, teleporting you back to the entrance.
- Moxxi’s Big Encore Machine appears nearby, allowing you to pay for an instant respawn of Mimicron.
- A red chest before the teleport orb respawns each run, giving additional chances at world-drop Legendaries.
This setup makes Mimicron one of the most efficient early bosses to farm, both for gear progression and practice against shield-plus-armor mechanics.
