The Core Observer boss fight in Borderlands 4 is optional, but does drop some pretty amazing legendaries, once you get there. In order to take part in this fight, you must at least have completed the One Fell Swoop main story mission, so you can start cracking the various Order Bunkers.It’s pretty easy to get to, and it’s not a terribly challenging boss to overcome, provided you have electrical damage. This is a boss with two sets of shields, so you’ll want to come packing a gun that can shred through those. Here’s everything you need to know about the Core Observer boss fight.Where to find Core Observer boss in Borderlands 4The Core Observer boss fight is found in Borderlands 4’s Fadefields Region, specifically Blacklime Bunker in The Howl. You’ll have to do some double jumping and gliding to get there, but if you follow the quest marker from the Rootdown Estates Fast Travel, it won’t take long to reach.Here’s where you can find the Core Observer: Blacklime Bunker (Image via 2K Games)You’ll have to also use one of the nearby platforms and throw the gunk bomb at the door, so you can get in. It’s a relatively short dungeon, as far as Bunkers go, and there’s lots of Order minions in it. That’s another reason you should bring electrical damage if possible; it also makes quick work of them and their shields.Core Observer’s attacks in Borderlands 4Core Observer can shoot a bombardment of basic laser attacks at you.The Core Observer can summon a swarm of Corroborating Witness enemies with a variety of elemental attachments. These explode if they get too close.The Core Observer can spin wildly in place, and fire lasers in every direction at once.Compared to fights like the Rocken Roller in Borderlands 4, the Core Observer isn’t terribly difficult to deal with. It only has a few attacks, and you can hide behind cover to deal with two of them. It’s going to likely show up as just a single level higher than you (37, when I arrived at 36).Tips to defeat Core Observer in Borderlands 4Core Observer has a Shield Health Bar, Normal Health Bar, then a Shield Health Bar again in Borderlands 4, so I cannot stress enough how great electrical damage is here. The first time I fought it, I had an Electric/Cryo version of the Sweet Embrace legendary from Moxxi’s Tip Jar, so I swapped to Cryo for the yellow health bar and it vanished into thin air in no time. This is without an infinite damage build for Vex, mind.Pew pew pew pew! (Image via 2K Games)The normal laser attacks aren’t anything to be threatened by, honestly. It’s the swarm of Corroborating Witnesses that are the threat in this Borderlands 4 boss fight. They act as grenades that fly straight at you.Thankfully, you can just shoot them down. In the final moments of the fight, it might start spinning in place wildly. If so, immediately take cover. The lasers ricochet and fly everywhere, and they can certainly hurt. If you take cover, there’s no threat, though. Other than that, just shred through its health and it drops pretty quick.Noteworthy drops from Core Observer in Borderlands 4There are several Legendaries that have a chance to drop from the Core Observer boss fight in BL4. Divided Focus is one of my favorite guns in the game, and if I had an updated version for my level, I might use it as a swap from my shotguns.The Defribillator is also fantastic for its ability to automatically replenish a Repkit Charge when your health drops. It’s a 50/50 shot, but it can sure be a lifesaver. Bully is just a great pistol with extra damage, thanks to the Drones it can unleash:Bully (Pistol): Defense Shield: When Gun Shields are activated, launches an Attack Drone every 14s.Defibrillator (Repkit): Cardiac Shock: When Health goes below 20%, there is a 50% chance to replenish a Repkit ChargeDivided Focus (Assault Rifle): Conqueror – Fires bouncing Projectiles that pierce enemiesCheck out our other Borderlands 4 guides and featuresAll Weapon Manufacturers in Borderlands 4Who is the villain of Borderlands 4?What are Enhancements in Borderlands 4?Does Borderlands 4 have co-op and crossplay?
