To dominate Mayhem 10/11 in Borderlands 3, you need top-tier legendary weapons with the right anointments. This guide covers the exact boss locations, DLC requirements, and farming strategies for the best base-game and DLC weapons in the current sandbox.
Base Game Legendary Weapons
The Maggie (Jakobs Pistol)
The Maggie is a legendary Jakobs pistol that fires 6 pellets per shot at the cost of one ammo. It is one of the highest DPS pistols in the base game and a staple for FL4K critical hit builds.
| Weapon Type | Element | Source (Boss) | Location | Base Drop Rate |
| Pistol | Kinetic (None) | Tremendous Rex | Cistern of Slaughter (Promethea) | ~15% |
- Farming Tip: Tremendous Rex is the final boss of the Cistern of Slaughter arena. To farm him efficiently, kill him, grab the loot, and immediately kill your character (with a rocket or grenade) before the round officially ends. You will respawn at the vending machines, and the boss wave will reset without you having to play the entire arena again.
DLC 2: Guns, Love, and Tentacles
Soulrender (Dahl Assault Rifle)
The Soulrender has a unique effect where firing the weapon has a 20% chance to spawn homing purple skulls that deal massive splash damage. It is a top-tier choice for Moze splash damage builds.
| Weapon Type | Element | Source (Boss) | Location | Base Drop Rate |
| Assault Rifle | Any | Tom and Xam | Heart’s Desire (Xylourgos) | ~15% (per boss) |
- Farming Tip (The Tom & Xam Glitch): Tom and Xam spawn together. Kill only one of them, collect the loot, and immediately fast-travel back to the Heart’s Desire fast-travel station (which is right outside their arena). Both bosses will instantly respawn. Do not kill both, or you will have to save and quit to the main menu.
Hydrafrost (COV Pistol)
The Hydrafrost is a cryo-exclusive COV pistol. Killing an enemy with this weapon grants a 200% weapon damage buff and causes every second shot to fire incendiary or shock projectiles for 10 seconds.
| Weapon Type | Element | Source (Boss) | Location | Base Drop Rate |
| Pistol | Cryo | Shiverous the Unscathed | Cursehaven (Xylourgos) | ~12.5% |
DLC 5: Arms Race (Designer’s Cut)
The Arms Race mode is a battle-royale-style instance where you drop in with no gear. To keep the legendaries you find here, you must extract them at a Gear Extractor before dying to the Murdercane.
Plasma Coil (Maliwan SMG)
The Plasma Coil is widely considered the best SMG in the entire game. It is locked to Shock and Radiation elements and fires a 16-round burst with incredibly high splash damage.
| Weapon Type | Element | Source (Chest) | Location | Base Drop Rate |
| SMG | Shock / Radiation | Blind Sage Chest | Stormblind Complex (Arms Race) | ~20% (From specific chest) |
Kickcharger (Vladof Rocket Launcher)
The Kickcharger is a unique heavy weapon that you must charge up by sliding. Sliding at maximum speed charges the weapon, increasing its damage by 300%. It is best used for one-shotting bosses on Zane.
| Weapon Type | Element | Source (Chest) | Location | Base Drop Rate |
| Heavy | Any | Bloodeye Chest | Stormblind Complex (Arms Race) | ~15% (From specific chest) |
All Other Arms Race Legendaries
While Plasma Coil and Kickcharger are the primary targets, Arms Race contains a massive pool of exclusive loot. All of these can drop from any enemy or airdrop in the Stormblind Complex, but they have higher drop chances at their dedicated chests:
- Dark Army (SMG): Spawns flying drone guns that shoot at enemies. (Red Sands Chest)
- Tizzy (Pistol): Extremely high fire-rate COV pistol. (Air Drop Chest)
- Trickshot (Pistol): Jakobs pistol that shoots faster as you fire. (Madwidth Chest)
- Boogeyman (Sniper): Vladof sniper with a chance to not consume ammo. (Plunderer Chest)
- Gas Mask (Shield): Increases Fight For Your Life time by 50%. (Heavyweight Chest)
- Holy Grail (Artifact): Increases max health and buffs revived allies. (Blind Sage Chest)
- Clockwork Res (Pistol): Shooting a downed ally instantly revives them. (Heavyweight Chest)
