All Legendary Weapons and Enhancements Locations in Borderlands 4

In Borderlands 4 you will find many legendary weapons as Enhancements all over the map. Since most of the weapons are dropped from bosses a few are also dropped randomly. As for the enhancements you will get them as you get more weapons. In this guide we have located all the legendary weapons that we have found till now, tips on how to defeat the bosses and all the legendary weapons that we have found till now. 

All Legendary Weapons and Items Locations & Effects

Legendary weapons can increase your build stats and make the game easier. It’s super helpful to know where to find them. Most of the Legendary Weapons are tied to certain bosses, and each time you defeat them, there is a small chance they will drop that exact item.

Below are all legendary weapons and Items along with their Locations & Effects, we have found so far. We will update all the remaining information as soon as we get to know about it. 

Splashzone

You will run into Splashzone during the Recruitment Drive main mission, where he shows up as a boss fight in Riptide Grotto, found in the Coastal Bonescape area of The Fadefields. Once you’ve finished that mission, you can go back and farm him as many times as you want for his drops.

How to Defeat the Splashzone

Splashzone has a flesh health bar, so Incendiary weapons work best. If you don’t have them, Kinetic, Cryo, or Radiation weapons will also be useful. Avoid Shock and Corrosive weapons, they do not deal much damage to flesh. Splashzone likes to charge at you and hit you with melee attacks. 

The best way to stay safe is to run around the arena. Watch out for other enemies and make sure you don’t fall off the edges. Shoot the explosive barrels in the arena to deal extra damage. They’re great for taking out smaller enemies quickly or giving Splashzone damage.

Splashzone Rewards

When you take down Splashzone, you’ve got a chance at some great loot. The main prize is the Lead Balloon, a powerful legendary shotgun. On top of that, Splashzone can also drop the Firewerks legendary shield and the Jelly Jelly legendary grenade, so it’s always worth the fight if you’re hunting for rare gear. 

If it doesn’t drop the first time, don’t worry, you can use Moxxi’s Big Encore just outside the boss arena to make Splashzone appear again. Keep in mind, the Encore costs cash, and the price goes up as you level.

Voraxis

Voraxis is an optional boss you can fight inside Timid Kyle’s Neglected Opening, found in the Abandoned Auger Mine over in the Coastal Bonescape area of the Fadefields. You will only be able to access this mine after finishing the Shadow of the Mountain main mission.

Once you’ve beaten Voraxis, you’re free to farm it again whenever you like. Just head back to the same spot and use Moxxi’s Big Encore Machine near the arena entrance to spend some cash and trigger the fight again.

How to Defeat the Voraxis

When you’re fighting Voraxis, try to aim for its eyes; that is its weak spot, and hitting them will drain its health much faster. Watch out for its charging attack too. Voraxis winds up before it bolts straight ahead, so be ready to dash to the side at the right moment. 

On PS4, that’s the left stick plus Circle, on Xbox it’s the left stick plus B, and on PC you will want to hit Shift while moving. It also likes to throw molten boulders that explode on impact. These hit hard, so keep your distance and stay on the move to avoid getting caught in the blast.

Voraxis Rewards

Beating Voraxis is worth the effort because it can drop some really strong gear. You might get the Darkbeast legendary SMG, the Potato Thrower IV legendary assault rifle, or even the Buoy legendary grenade. Each drop feels like a solid reward for taking down this tough boss.

The Oppressor

You will face The Oppressor during the main mission A Lot to Process, where it shows up as the boss fight in The Killing Floors, found in the Dissected Plateau area of the Fadefields.

After you finish that mission, you can go back and farm The Oppressor whenever you want. Just return to the arena and use Moxxi’s Big Encore Machine near the entrance to spend some cash and trigger the fight again.

How to Defeat the Oppressor

Since The Oppressor is almost always airborne, you will want to bring along scoped weapons like sniper rifles or certain assault rifles. That way, you can reliably hit its weak spot from a distance without wasting shots.

Another thing to watch out for is its cluster missiles. These can quickly overwhelm you if you ignore them, so try to shoot them down as soon as they’re launched. Taking them out early will save you from getting caught in a storm of explosions.

The Oppressor Rewards

Taking down The Oppressor can really pay off, since it has a chance to drop some excellent legendary gear. You might walk away with the Asher’s Rise sniper rifle, the Onslaught SMG, the Blood Analyzer repkit, or even the Streamer heavy weapon. Each one is a powerful reward that makes the fight worth farming.

Bio-Bulkhead

You will come across Bio-Bulkhead as the boss fight in the One Fell Swoop main mission, set in the Synthetic Nave within the Dissected Plateau area of the Fadefields.

Once that mission’s done, you can go back and farm Bio-Bulkhead whenever you like. Just head back to the arena and use Moxxi’s Big Encore Machine near the entrance to spend some cash and start the fight again.

How to Defeat the Bio-Bulkhead

At the start of the fight and whenever Bio-Bulkhead begins a new health segment, it becomes immune to all damage. During these moments, grab a Locust Sample from around the arena and throw it at the boss. This will temporarily break its immunity and let you start dealing damage again.

When its armor is exposed, your best bet is to use Corrosive or Cryo weapons, as they deal extra damage to armored enemies. Weapons that do Shock, Radiation, or Incendiary damage won’t be very effective, though Kinetic weapons can serve as a backup if you run out of Corrosive options. Be careful of its AOE ground slams, which send out powerful shockwaves. Keep moving and jump at the right moments to avoid getting hit.

Bio-Bulkhead Rewards

Defeating Bio-Bulkhead can net you some really valuable loot. You might get the Budget Deity legendary pistol, the Sho Kunai legendary grenade, or the Waterfall legendary grenade all solid rewards that make taking down this boss worth your time.

Primordial Guardian Inceptus

You will face Primordial Guardian Inceptus in the Arch of Inceptus, located in the Dissected Plateau area of the Fadefields. This boss guards the Vault of Inceptus, which you can access after collecting and placing all the Fadefields Vault Key Fragments.

After you defeat Inceptus, you can farm it again as many times as you like. Just return to the arena and use Moxxi’s Big Encore Machine near the entrance to spend some cash and start the fight again.

Primordial Guardian Inceptus Rewards

Defeating Primordial Guardian Inceptus can reward you with some impressive legendary loot. You might walk away with the Lucky Clover pistol, the Husky Friend shotgun, the Extra Medium shield, or the Ravenfire heavy weapon. On top of that, there’s a chance to get powerful class mods like the Firey Elementalist, Rewarding Filantropo, Reactor or the Electric Avatar, making this boss fight well worth the effort.

Backhive

Backhive is an optional boss you can find in The Claim: Abandoned Auger Mine, located in the Dissected Plateau area of the Fadefields. This area becomes available after you finish the Shadow of the Mountain main mission.

Once you beat Backhive, you can come back and farm it as many times as you want. Just head back to the same spot after the mission and use Moxxi’s Big Encore Machine near the arena entrance, spend some cash, and you can fight Backhive again for more loot.

How to Defeat the Backhive

During the fight, Backhive will keep summoning Nitro Kratches, take them out as soon as they show up because they explode and can do a lot of damage fast. Backhive also uses AOE (area-of-effect) attacks like ground slams and shockwaves. When you see it winding up, time your jump to dodge the damage.

If you try to keep your distance, it will charge straight at you. This can hurt a lot, so be ready to dash to the side to avoid it. But don’t let your guard down; if the charge misses, Backhive will immediately follow up with a ground slam, so be prepared to dodge again right after.

Backhive Rewards 

Defeating Backhive will reward you with Cindershelly (Legendary Shield).

Horace 

You will find Horace in Horace’s Oversight, located in the Hungering Plain area of the Fadefields. He shows up as a boss during the main mission, Down and Outbound.

After you finish the mission, you can go back and farm Horace for loot. Just return to the same spot and use Moxxi’s Big Encore Machine near the arena entrance, spend some cash, and you can fight him again whenever you want.

How to Defeat the Horace

During the fight, Horace will summon either a flying Witness or a homing mechanical projectile. Take these out as soon as possible; they can sneak up on you and deal a lot of damage if you ignore them. Try to leave a few ground enemies alive; they can actually help you. If you get knocked down, you can kill one to trigger Second Wind and get back into the fight.

In phase two, Horace starts using his Scythe. When he swings it, quickly dash left or right to dodge. You can even dash in midair, which helps avoid combo attacks or shockwaves on the ground. Horace will also shoot waves of projectiles at you often. Use the pillars in the arena for cover to block these and stay safe.

Horace Rewards

Defeating Horace will reward you with Aegon’s Dream (Legendary Assault Rifle), Lucky Clover (Legendary Pistol), Whiskey Foxtrot (Legendary Assault Rifle), Pacemaker (Legendary Repkit), and Sho Kunai (Legendary Grenade).

Sydney Pointylegs

Sidney Pointylegs is an optional boss you can find at The Prospects Ripper Drill Site in the Hungering Plain area of the Fadefields. You can access Ripper Drill Sites as soon as you discover them on your map, with no mission requirements.

After you beat Sidney, you can farm the boss for loot anytime. Just come back later and use Moxxi’s Big Encore Machine near the arena entrance. Spend a bit of cash, and you will be able to fight Sidney again.

How to Defeat the Sydney Pointylegs

When Sidney Pointylegs starts spinning, it summons two types of smaller enemies, Skitter Balms (mini versions of itself) and Sploders (explosive ones that chase you).

Take out the Skitter Balms first, because if you leave them alone, Sidney will absorb them to heal herself. Also, make sure to destroy the Sploders before they get too close; they explode and can deal a lot of damage.

Sidney’s legs are her weak spots, so aim for them whenever you can. Hitting the legs deals extra damage and can stagger her, making the fight a lot easier and faster. Keep your shots low to get the best results.

Sydney Pointylegs Rewards

Defeating Sydney Pointylegs will reward you with Noisy Cricket (Legendary Pistol), Swarm (Legendary Grenade), and Disc Jockey (Legendary Heavy Weapon).

Sludgemaw

You will find Sludgemaw at Watershed Gate in the Idolator’s Noose area of the Fadefields. This boss shows up during the side mission All Charged Up, but you will need to finish another side mission called Null and Void first to unlock it.

Once you’ve completed All Charged Up, you can come back and farm Sludgemaw for more loot. Just head to the same spot and use Moxxi’s Big Encore Machine near the arena entrance, pay some cash, and you can fight Sludgemaw again.

How to Defeat the Sludgemaw

Climbing onto the nearby cargo container is a smart move during the fight with Sludgemaw. It gives you a clear view to keep shooting and deal steady damage, while also helping you stay out of range of most of its melee attacks.

Sludgemaw Rewards

Defeating Sludgemaw will reward you with Birt’s Bees (Legendary Submachine Gun), Kickballer (Legendary Shotgun), and Onion (Legendary Shield).

Idolator Sol

You can find Idolator Sol in Fortress Indomita, located in the Idolator’s Noose area of the Fadefields. This boss shows up during the main mission Rush the Gate.

After you finish the mission, you can come back and farm Idolator Sol for loot. Just return to the same spot and use Moxxi’s Big Encore Machine near the entrance of the arena. Spend some cash, and you will be able to fight him again.

How to Defeat the Idolator Sol

When Idolator Sol becomes immune to damage, don’t panic, just wait for it to throw a bunch of rods around the arena. One of them will glow green. Find it, pick it up, and throw it back at Sol to break the shield and make it vulnerable again.

During the fight, Sol will also reveal green, blob-like weak spots on its body. When you see them, focus your attacks there to deal extra damage and finish the fight faster.

Idolator Sol Rewards

Defeating Idolator Sol will reward you with Onslaught (Legendary Submachine Gun), Goremaster (Legendary Shotgun), Golden God (Legendary Shotgun), Ultimate Bio-Robot (Gravitar Class Mod), Perpetual Dancer (Exo-Soldier Class Mod), Excitable Technomancer (Siren Class Mod), and Melting Furnace (Forgeknight Class Mod).

Foundry Freaks

You can fight Foundry Freaks in The Pitter Stain Ripper Drill Site in the Fadefields. The drill site makes the battle intense, with narrow spaces, industrial hazards, and very little room to make mistakes. To get there, just move through Idolator’s Noose until you reach the drill site arena—this is where the fight starts.

How to Defeat the Foundry Freaks

Head to the Foundry Freaks and use Moxxi’s Big Encore Machine to start the fight with all three bosses. Make sure your loadout is good for quickly clearing mobs and hitting bosses from a distance; long-range and AoE attacks work best.

During the fight, take out waves of smaller enemies whenever the bosses aren’t attacking, and focus on the bosses’ weak points when they’re exposed. Keep moving between bosses so you don’t get trapped, and use cover and movement abilities to stay safe.

Once all three are defeated, grab your loot quickly and leave the arena. Respawn timers are short, and more mobs can appear if you want to farm them again.

Foundry Freaks Rewards

Defeating Foundry Freaks will reward you with Chuck, Bloody Lumberjack, and Chaumurky.

Mimicron

You will find Mimicron in the Tipping Point Order Bunker in Idolator’s Noose. The Tipping Point bunker in Idolator’s Noose, Fadefields, can be a bit confusing at first, but opening the door is actually straightforward. Stand with your back to the door and go right to find a giant fan. 

Go inside the fan, take another right, and climb the ladder to reach a Locust station. Drop down through the hole in the floor and throw the Locust at the door to unlock it. Inside the bunker, you will need to open a few more doors by finding buttons and batteries, which are all in the same room.  At the end, you face the boss Mimicron.

How to Defeat the Mimicron

Mimicron is unique because it creates shielded copies of itself. The main boss has both a shield and armor, so using Shock and Corrosive or Cryo weapons is highly recommended.

Mimicron Rewards

Defeating Mimicron will reward you with Complex Root, Luty Madlad, and UAV.

Core Observer

You can find the Core Observer hidden in the Blacklime Bunker, a heavily fortified area in The Howl region of the Fadefields. This bunker becomes accessible as you progress through the story and offers a side challenge separate from the main bosses. To get there, head to the rocky outcrops near the bunker entrance on your map. You will need to navigate some natural platforms and gaps, so be ready for a bit of platforming.

Getting into the Blacklime Bunker requires careful movement and use of your abilities, so make sure you’re ready before the boss fight. First, you need to complete the main mission One Fell Swoop to unlock access to Order Bunkers across Kairos, including Blacklime.

To reach the bunker in The Howl, follow your map to a rocky platform near a unique rock with a tree growing from it. Jump across to a lower platform, then use your double jump and mantle to climb to a higher ledge where a Locust station is waiting. Grab the Locust and throw it at the bunker door to unlock it, then glide over and enter the passage.

Inside the bunker, crouch under a low pipe, cross a flooded room by gliding or swimming, and press the button to open the next door. Head up the stairs to a room with vending machines to restock ammo or health, then proceed to trigger the Core Observer’s appearance in the arena.

The boss has multiple phases, so choosing the right weapons is key. Its first and last phases have shields that are weak to Shock damage, while the middle armor phase is best handled with Corrosive or Cryo attacks. Before the fight, stock up on shock pistols or SMGs to strip shields quickly, and switch to corrosive rifles or cryo shotguns for the armor phase.

Bring high-mobility gear to dodge attacks and consider mods that boost elemental damage or health regeneration to make the fight easier and faster.

How to Defeat the Core Observer

Fighting the Core Observer is all about staying mobile and using cover while targeting its weak spots for big damage.

When you enter the arena, start circling left and right to avoid the boss’s initial attacks. Focus on its central eye with sniper shots or precise attacks while dodging thrown mines, hide behind cover if needed. Use Shock weapons to break the first shield bar, gliding sideways to make yourself a harder target, especially at long range.

When it enters the armor phase, switch to Corrosive or Cryo weapons and focus on the exposed core. Deal with small enemies that spawn so they don’t distract you. Watch out for the tractor beam attack, strafe or glide to escape its pull while continuing to chip away at the armor.

Once the armor is down, switch back to Shock weapons for the final shield phase. Keep moving, hit the eye whenever it’s exposed, and take the boss down to claim your rewards.

After defeating Core Observer, you can reset the fight quickly to farm for legendary loot. Teleport to the south exit of the bunker, fast travel back to the entrance, clear nearby enemies, and repeat the fight. Higher difficulty levels like Ultimate Vault Hunter give better drops.

With practice, the Core Observer becomes a reliable source of top-tier gear, making your adventures across Kairos much easier. This fight is a perfect mix of movement, strategy, and loot hunting in Borderlands 4.

Core Observer Rewards

Defeating Core Observer will reward you with a Defibrillator, Bully, and Divided Focus.

Skyspanner Kratch

Skyspanner Kratch is a huge bat-dragon boss you face during the Shadow of the Mountain mission. The fight mostly revolves around managing its constant movement and dealing with the minions it keeps sending at you.

How to Defeat the Skyspanner Kratch

The Skyspanner Kratch fight in Borderlands 4 isn’t too complicated, but its attacks can be really annoying. The boss has two health bars, but the second phase doesn’t add anything new, which makes things a bit easier. Playing as Vex helps a lot since your Specters can shoot and deal different elemental damage. The boss is fleshy, so its biggest weakness is Ignite.

Most of the fight is about dodging its attacks and minions. It launches a sonic blast repeatedly, trying to knock you into the poisonous water below. It spawns mini-Kratch enemies, which damage you on contact. Sometimes it flies in circles, releasing balloon-tied mini-Kratches that explode with different elements.

Its most dangerous attack is when it curls up its tail and spits out a bunch of tiny Kratch “missiles.” When you see this, double jump and glide away to avoid taking heavy damage. Another tough attack is when it floats around and releases balloons with mini-Kratches, they slowly drift toward you and explode for elemental damage.

Throughout the fight, stay mobile: jump between platforms, keep moving, and hit Skyspanner Kratch whenever you can. Watch out for the poisonous water, if the boss falls in it, loot can sometimes disappear, so keep that in mind. The key to this fight is dodging, mobility, and hitting its weak spots as often as possible while avoiding the mini-Kratches.

Skyspanner Kratch Rewards

Defeating Skyspanner Kratch will reward you with Hellfire, Hoarder, and Linebacker

Saddleback and Immortal Boneface

When you enter the Terminus Range, you will arrive at Cuspid Climb. To the east, you will spot a large Ripper hideout. If you explore deeper into this area, you will come across the Ripper Drill Site called the Old Scrape, marked by a metal drawbridge and the bones of a giant creature.

As with other Ripper Drill Sites, you will need to provoke the boss by defeating the waves of Rippers in the area. Once you do, the bosses Saddleback and Immortal Boneface will appear, ready for battle.

How to Defeat the Saddleback and Immortal Boneface

When facing these bosses, your main focus should be on Saddleback, the large Meathead carrying Immortal Boneface. Saddleback has an Armor bar and a Flesh bar, so using Corrosive or Cryo for armor and Incendiary for flesh works best.

Once you take down Saddleback, Immortal Boneface loses his immortality buff and becomes vulnerable. At this point, use Shock weapons for his shield and Incendiary for his flesh to deal the most damage.

Saddleback and Immortal Boneface Rewards

You will get Lucian’s Flank, Hellwalker, and War Paint after defeating both the bosses. 

Shadowpelt

Shadowpelt is an optional boss you can find in the Whistler’s Maw Abandoned Auger Mine, located in Cuspid Climb within the Terminus Range. You will be able to access this area after completing the Shadow of the Mountain main mission.

Once you’ve defeated Shadowpelt, you can farm it again anytime. Just return to the arena and use Moxxi’s Big Encore Machine near the entrance to spend some cash and start the fight over.

How to Defeat the Shadowpelt 

When fighting Shadowpelt, its shield makes it invisible, so your first priority is to take down the shield quickly using Shock damage. Once you hit it, Shadowpelt will turn visible and take damage, but the shield will reactivate soon after, so be ready to destroy it multiple times fighting it while invisible is much harder.

Shadowpelt also fires projectiles that explode on impact. These AOE blasts deal heavy damage if you stay too close, so keep moving and maintain a safe distance to avoid getting hit.

Shadowpelt Rewards

Defeating Shadowpelt can reward you with some valuable legendary loot, including the Vamoose sniper rifle, the Sparky Shield, and the Slippy legendary grenade, making the fight worth taking on.

Skull Orchid 

You can find Skull Orchid in the Grindstone of the Worthy, a cave located deep within Embossed Faults. To reach its lair, you will need to progress through the main story missions up to at least A Lot to Process. The fight takes place in the heart of an Abandoned Auger Mine called The Pigeonhole, right inside the cave.

How to Defeat the Skull Orchid

To make things even trickier, Skull Orchid is a Creep, meaning it can randomly change its elemental type to counter the damage you’re dealing. It has a Flesh health bar, which is most easily damaged with Incendiary weapons.

For its weak spot, aim for the tendrils hanging from its mouth its large eyes and bulbous head are protected by a hard shell, so attacking them won’t do much.

Skull Orchid Rewards

You will get Faulty Detonator, Spied Dextrous Oak-Aged Cask and Roach after defeating the boss. 

Callous Harbringer

Callous, Harbringer of Annihilating Death is an optional boss you can find in the Craven’s Nook Order Bunker, located in the Heart of the Mountain within the Terminus Range. You will gain access to this bunker after completing the One Fell Swoop main mission.

Once you’ve defeated Callous, you can farm it again anytime. Just return to the arena and use Moxxi’s Big Encore Machine near the entrance to spend some cash and start the fight over.

How to Defeat the Callous Harbinger

When fighting Callous, watch out for his ground slams, which send out damaging shockwaves across the arena. Time your jumps carefully to clear the waves and avoid taking damage. He also fires barrages of projectiles. When this happens, quickly move behind the elevated platform for cover this keeps you safe while giving you a chance to peek out and fire back.

Once his shield is gone, Callous becomes more aggressive and will occasionally charge at you. Keep moving and dash to the side at the right moment to avoid taking heavy damage. On PS4, dash with the left stick plus Circle, on Xbox it’s left stick plus B, and on PC it’s Shift plus movement keys.

Callous Harbinger Rewards

Defeating Callous, Harbringer of Annihilating Death can reward you with some impressive legendary weapons, including the Hot Slugger shotgun, the Kaleidosplode shotgun, and the Atling Gun heavy weapon, making the fight well worth your effort.

Battle Wagon

This enemy appears in the middle part of Stoneblood Forest in the Terminus Range. They spawn immediately after you defeat the bandits at The Lowering March Ripper Drill Site, which is just above the Snowy Wells Safehouse.

How to Defeat the Battle Wagon

The Battle Wagon is a massive elephant-like creature covered with Ripper riders, turrets, and rocket launchers. It has a thick Flesh health bar, so using Incendiary weapons is your best bet for dealing damage. While attacking the boss, don’t forget to target the enemies on its back, as they can cause trouble. The Battle Wagon takes quite a few bullets to bring down, and even after it’s defeated, you will need to eliminate the riders to claim its loot.

Battle Wagon Rewards

You will get Finnity XXX-L and Compleation after defeating the boss. 

Primordial Guardian Origo

You will need to collect all Terminus Range Vault Key Fragments first. Find Origo at The Low Leys, Arch of Origo.

How to Defeat the Primordial Guardian Origo

Origo has two Shield health bars and a wide range of attacks, which it can use in any order. During the fight, it will spawn Kratches, which you can kill to trigger a Second Wind if you get downed.

Origo cycles its elemental damage between Cryo and Incendiary. Its moves stay mostly the same, except for Ice Spikes, which become Fire Bursts when it switches to Incendiary form. The arena has grapple points some can save you if you’re knocked off the map, while others on the ground can launch you into the air.

Primordial Guardian Origo Rewards

You will get the Kaoson, Watts 4 Dinner, Bottled Lightning, Buster, Shatterweight, Driver, and the Kindred Spirits after defeating the Origo.

Vile Prototype

After completing the mission, you can farm Vile Prototype as many times as you like. Just return to the arena and use Moxxi’s Big Encore Machine near the entrance to spend some cash and trigger the fight again. 

How to Defeat the Vile Prototype

At the start of the fight, Vile Prototype is invulnerable because of the Eridium crystals covering his body. Take out these crystals first to make him vulnerable to your attacks.

After destroying a crystal, a Vile Ordonite will appear. Be sure to eliminate it quickly, or it will restore the crystal and make him invincible again.

When attacking, aim for his head. This is his weak spot, and hitting it will deal extra damage, helping you bring down his health faster.

Vile Prototype Rewards

Defeating Vile Prototype can earn you some top-tier legendary loot, including the Rangefinder pistol, the King’s Gambit pistol, and the Heavyweight shield. These powerful rewards make the fight well worth your effort.

In the second phase, he will sometimes trigger a huge explosion in the center of the arena that can deal serious damage. To stay safe, quickly grab onto one of the floating rock platforms until the blast passes.

Vile Lictor Rewards

There’s also a chance to score powerful class mods like Injected Undead Eye, Precise Instigator, Universal Generator, or Ember Blacksmith, making this boss fight well worth the effort.

Moon-Maddened Callis

You will run into Moon-Maddened Callis at the very end of the Elpis Orbital Shatterfield. This spot becomes available as a fast travel station in the upper-left part of Carcadia Burn once you’ve completed the main mission “Another Day, Another Universe.”

How to Defeat the Moon-Maddened Callis

When you fight Moon-Maddened Callis, you will notice she comes with two Armor bars followed by two Flesh bars. This makes Corrosive or Cryo weapons perfect for the first phase, and then you will want to switch over to Incendiary to finish her off. 

Callis fights like a jumpy scorpion, keeping her distance while striking out with her tail and covering the arena in a dangerous red web that damages you if you touch it. As for loot, don’t expect much consistency she doesn’t seem to have a set legendary pool and instead drops random legendaries, and even then, the drop rate feels pretty low.

Moon-Maddened Callis Rewards

You will get the Ohm I Got and the Gamma Void as a reward after defeating her. 

Queen Callis

How to Defeat the Queen Callis

When fighting Callis, the Ripper Queen, she will summon a flying support drone that drops bombs across the arena. Take it out quickly, or the arena will become a hazardous mess.

After her shield is broken, Callis will leap out and become immune, summoning red constructs that slow and damage you if you touch them. During this time, focus on defeating the other enemies. Once most of them are gone, Callis will return to the arena and become vulnerable again.

She also has a leaping tail slam attack her tail glows red just before she jumps and spins, so use that as a cue to dash out of the way. On PS4, dash with the left stick plus Circle, on Xbox it’s left stick plus B, and on PC it’s Shift plus movement keys. Timing your dodge will help you avoid heavy damage.

Fractis

The Crawlcroft is hidden in Carcadia Burn, inside the Grindstone of the Worthy. To get there, head into the Order base shown on the map and look for a cave that leads deeper inside. This cave will eventually take you to the Crawlcroft Bunker. 

To open the bunker door, go to the opposite side of the main entrance and check beneath the grapple platform you will find a Locust station under some metal bars. Grab the Locust and toss it at the door to unlock the way forward. From there, it’s a straightforward path. Just push through the half-open doors, crouch through the gaps in the walls, and stick to the left side until you reach the boss, Fractis.

How to Defeat the Fractis

Fractis can be a bit trickier than he first appears. Partway through the fight, he will summon a golden copy of himself that comes with a Shield.

All three of these bosses fight the same way. They stay airborne, start with Shields that are best taken down with Shock weapons, and then have a Flesh bar that melts under Incendiary damage.

When fighting Rocken Roller, watch out for its rolling spin attacks, which sweep across the arena. Staying on higher rocks keeps you safe while letting you keep firing.

To actually damage Rocken Roller, target the glowing Eridium Crystals on its back these crystals make it immune to attacks, so you need to destroy them first.

Driller Hole

You will face Driller Hole during the main mission Unpaid Tab, located in Queen’s Cradle, Tonnage Peel in Carcadia Burn.

After finishing the mission, you can farm Driller Hole as many times as you like. Just go back to the arena and use Moxxi’s Big Encore Machine near the entrance to spend some cash and start the fight again.

How to Defeat the Driller Hole

When fighting Driller Hole, watch out for the missiles it launches from underground. These track your position and explode when they surface, so stay on the move jump, glide, or climb onto crates, and use enemies or objects around the arena as cover to avoid taking damage.

It also fires a barrage of missiles from above. Keep strafing and use the ripper machine in the center of the arena as a shield to block them.

Finally, Driller Hole will sometimes charge at you if you’re far away. Pay attention to its wind-up animation and dash to the side at the right moment to avoid getting hit. On PS4, dash with the left stick plus Circle, on Xbox it’s left stick plus B, and on PC it’s Shift plus movement keys.

How to Defeat the Axemaul 

When you face Axemaul in the Toil of Spoiling Vis, keep in mind that the fight has two phases. The second phase kicks in as soon as you reduce Axemaul’s health bar to zero the first time. Don’t be fooled Axemaul survives the first phase because you’re mainly tearing through its armor, not its true health.

Axemaul Rewards

You will get the Kill Spring, Buzz Axe and the Bod as a reward afyer defeating it. 

Bio-Thresher Omega

How to Defeat the Bio-Thresher Omega

Bio-Thresher Omega is a bigger, glowing version of its kind. It’s heavily armored, so you will need to throw gas canisters at it before you can deal any real damage. The fight is a cycle: the boss will repeatedly pop in and out of the ground, becoming immune each time. As soon as it surfaces, throw a gas canister and then start shooting to chip away at its health. Keep repeating this process until it’s defeated.

Bio-Thresher Omega Rewards

You will get the Bug Bear and the Truck after defeating it. 

CorrupTed, Experiment 42, and Experiment

This boss appears during the side mission “Below the Surface” in Terminus District.

Primordial Guardian Timekeeper

You will find The Timekeeper in the Tower’s Control Room, the farthest area from Upper Dominion in the Terminus District of Dominion. Once you reach this spot, you can take the elevator up to face the final fight, which is actually a battle against two bosses at once.

How to Defeat the Timekeeper 

First, you will face The Timekeeper, who mixes things up with teleportation, blinding attacks, and energy beams to try and take you down. During this fight, he has three types of health: Shield (weak to Shock), Armor (weak to Corrosive or Cryo), and Flesh (weak to Incendiary).

Once you take him down, he moves into his second phase as the Primordial Guardian Timekeeper. He still has the same three health bars, but now he stomps around the arena, making it even trickier for Vault Hunters trying to farm his loot.

Timekeeper Rewards

You will get the Timekeeper’s New Shield, Borstel Ballista, Symmetry, Plasma Coil and the Star Helix as a reward for defeating it. 

Directive-O

To access Ironwall Resolve, you first need to have Dominion unlocked. Start by heading to Beth at Lakeside Properties in the Fades District and complete her side mission, One Gassy Issue. After that, make your way to the Terminus District to find Ironwall Resolve in the Praetor’s Lecture.

Before going up the stairs to the door, check to the left for a Locust station hidden in a pile of trash. Grab it, carry it upstairs, and throw it at the door to progress. The bunker itself is a bit tricky, but just move through the open rooms, use platforms to deactivate the forcefields, and repeat in the other room. Once that’s done, the path to the Directive-O boss fight will be open.

How to Defeat the Directive-O

This boss isn’t too dangerous. Focus on breaking its Shield bar with Shock weapons first, then switch to Corrosive or Cryo to melt through its Armor.

Directive-O Rewards

You will get the Bonnie and Clyde, Whiskey Foxtrot, and the Rowan’s Charge as a reward after defeating it. 

Bramblesong

Bramblesong is an optional boss you can find in the Bittervein Abandoned Auger Mine, located in Stoneblood Forest within the Terminus Range. You will be able to access this mine once you’ve completed the Shadow of the Mountain main mission.

After defeating Bramblesong, you can farm it again anytime. Just head back to the arena and use Moxxi’s Big Encore Machine near the entrance to spend some cash and start the fight over.

How to Defeat the Bramblesong

When fighting Bramblesong, watch out for its sweeping melee attacks if you get too close, it can deal a lot of damage. Luckily, there’s a boulder in the arena you can use as cover, giving you a safe moment to heal or fire back. Bramblesong also launches volleys of projectiles that explode on impact. 

Make sure to keep moving and avoid the blast zones, or you will take heavy damage. It’s also smart to leave a few enemies alive around the arena. If you get downed during the fight, killing one of them can trigger Second Wind, letting you get back on your feet and continue the battle.

Bramble Song Rewards

Defeating Bramblesong can reward you with some solid loot, including the Convergence legendary shotgun and the Disco legendary grenade. Both are powerful drops that make taking on this optional boss worthwhile.
