The Borderlands franchise is famous for its wild arsenal of weapons, and among the fan favorites that have made a triumphant return in Borderlands 4 Items is the Kaoson. First introduced in Borderlands 3 as a Children of the Vault assault rifle with insane splash damage potential, the Kaoson is back and more powerful than ever. Whether you’re a returning Vault Hunter who remembers melting bosses with it in BL3 or a new player curious about why this gun gets so much hype, the Kaoson is worth hunting down.
In this guide, we’ll cover everything you need to know about obtaining the Kaoson in Borderlands 4: its stats, unique perks, farming sources, dedicated drops, Mayhem scaling, and how to build around it for maximum destruction.
What Is the Kaoson?
The Kaoson is a Legendary Dahl Assault Rifle. Like most Dahl weapons, it retains the manufacturer’s signature traits: burst fire, fast reload speed, and tight accuracy. But unlike typical Dahl rifles, the Kaoson has two features that make it stand out:
Explosive Splash Damage – Instead of firing ordinary bullets, the Kaoson’s projectiles explode on impact, dealing both bullet and splash damage simultaneously.
Sticky Bomb Mechanic – Some variants allow bullets to stick to enemies and explode shortly after, multiplying damage when several rounds attach before the detonation.
These mechanics make the Kaoson an incredibly strong hybrid weapon, excelling at mobbing crowds of enemies and chunking bosses alike. It deals both direct hit and AoE damage, making it scale exceptionally well with splash-based skills and elemental builds.
Why You Want the Kaoson
Before we jump into the farming details, it’s worth emphasizing why the Kaoson is worth your time:
Versatility – Works in both close-quarters and mid-range combat.
Elemental Variety – Drops in all elements, including Cryo, Shock, Corrosive, Fire, and Radiation.
Burst DPS – Can shred bosses by stacking sticky rounds before the explosion.
Splash Synergy – Synergizes with splash or grenade damage bonuses, turning it into a mini-rocket launcher in AR form.
If you’re a player who loves high-damage rifles that can clear mobs and still hold up in boss fights, the Kaoson belongs in your arsenal.
Where to Get the Kaoson in Borderlands 4
The Kaoson is a world-drop legendary, which means in theory it can drop from any loot source in Borderlands 4. However, just like in BL3, it also has dedicated drop sources that make farming it much more efficient.
Dedicated Drop Source: General Taiven
Location: The Blacksite Barracks on Roguehaven Prime.
Mission Requirement: Must complete the main story quest Rebel Yell to unlock the Blacksite.
Arena: General Taiven spawns inside a heavily fortified courtyard filled with turrets and elite soldiers.
Respawn Method: Fast travel to “Barracks Outer Gate,” clear the arena, defeat Taiven, and repeat.
General Taiven has about a 15% chance to drop the Kaoson on normal difficulty, which increases with Mayhem levels.
Other Farming Sources
While General Taiven is the most reliable source, the Kaoson can also drop from:
Raid Bosses such as the Vile Prototype and The Maw Tyrant.
Legendary Chests in endgame Chaos Trials.
World Drops from badass enemies across Roguehaven Prime and Dahl-controlled maps.
If you’re actively targeting the Kaoson, stick to farming Taiven, as world drops dilute the pool too much.
Farming the Kaoson: Step-by-Step
Here’s how to farm the Kaoson as efficiently as possible:
Unlock Roguehaven Prime – Progress through the main campaign until you finish Rebel Yell.
Fast Travel to Barracks Outer Gate – This puts you close to General Taiven’s arena.
Prepare Your Loadout – Taiven uses shock-heavy weapons and shielded troops. Bring corrosive or shock weapons to deal with her.
Defeat General Taiven – Focus fire, clear adds quickly, and stay mobile to avoid turret fire.
Check for Kaoson Drop – If it doesn’t drop, save/quit and repeat.
With a 15% dedicated drop rate, expect the Kaoson to drop within 5–10 kills on average, though RNG can be streaky.
Mayhem Level Scaling
The Kaoson, like all legendaries in Borderlands 4, scales with Mayhem levels. Higher Mayhem levels not only increase the chance of it dropping, but also significantly buff its damage.
Mayhem 1–3: Base damage scales normally. Useful but not game-breaking.
Mayhem 4–6: Splash and sticky mechanics scale drastically, making it shine in mobbing situations.
Mayhem 7–10: The Kaoson becomes a boss-melting machine, especially with splash and elemental builds.
If you plan on using the Kaoson as your main weapon, farming it on Mayhem 6 or above is highly recommended for maximum damage scaling.
Best Prefixes and Parts
Since Borderlands 4 continues the random parts system, the Kaoson can drop with different grips, stocks, and barrels. Here’s what to look for:
Best Elements:
Corrosive for armored bosses.
Cryo for crowd control.
Shock for shield-heavy zones.
Preferred Barrel: Dahl burst fire (3-round or 4-round burst). These maximize sticky damage output.
Anointments:
“+200% splash damage while Action Skill is active”
“+100% elemental damage after using Action Skill”
“Consecutive hits increase weapon damage”
The right anointment can push the Kaoson into top-tier DPS territory.
How to Build Around the Kaoson
To maximize the Kaoson’s potential, you’ll want to pair it with characters and builds that boost splash damage, elemental bonuses, or sticky mechanics.
Amara (Siren) – Elemental Queen
Her elemental damage bonuses make Kaoson variants devastating.
Ties perfectly with her Phasegrasp + DoT builds.
Shock Kaoson variants can strip shields in a blink.
Moze (Gunner) – Splash Damage Goddess
Moze’s splash bonuses stack multiplicatively with the Kaoson’s explosions.
Short Fuse + Kaoson turns mobs into explosions chains.
Radiation Kaoson synergizes beautifully with her splash loop.
FL4K – Crit Master
Sticky rounds crit extremely well when stacked.
Pair with Fade Away builds to land guaranteed critical Kaoson shots.
Zane – Movement and Utility
Kaoson works as a mid-range mobbing rifle for Zane’s clone/sentinel builds.
Anointments that boost damage while moving pair perfectly.
How the Kaoson Performs in Endgame
In Chaos Trials and Mayhem 10 content, the Kaoson remains one of the most consistent legendaries thanks to its splash and sticky mechanics. It shines in:
Mobbing: Explosions chain across enemies, clearing rooms fast.
Boss Fights: Sticky stacking + splash leads to huge bursts of damage.
Raid Content: With proper anointments, it keeps pace with rocket launchers for sustained DPS.
The only real weakness of the Kaoson is ammo consumption. Like in BL3, it chews through AR ammo quickly. Pairing it with ammo regeneration class mods or skills (like Moze’s Redistribution or Zane’s kill skills) makes farming smoother.
Tips for Farming and Using the Kaoson
Always Farm in Mayhem 6+ – Otherwise you’ll end up replacing it quickly.
Bring Corrosive for Taiven – Makes the farm faster since she’s shielded and armored.
Don’t Ignore World Drops – If you’re farming Chaos Trials anyway, keep an eye out for incidental Kaoson drops.
Stock Ammo SDUs – The Kaoson is ammo-hungry; max out AR SDUs from Marcus.
Elemental Matchups Matter – Always carry at least two elemental Kaosons for flexibility.
Final Thoughts
The Kaoson in Borderlands 4 continues its legacy as one of the most versatile and destructive assault rifles in the series. With explosive splash mechanics, sticky-round stacking, and elemental flexibility, it’s a weapon that feels great in both casual play and high-level Mayhem farming.
By targeting General Taiven on Roguehaven Prime, you can reliably farm the Kaoson and start experimenting with its many elemental variants. Whether you’re a Moze player chasing splash synergies, an Amara main stacking elemental DoTs, or just a Vault Hunter who loves big explosions, the Kaoson deserves a slot in your arsenal.
If you’re only going to grind one legendary AR in Borderlands 4 Sniper Rifle, make it the Kaoson—it’s pure chaos, in the best possible way.
