How to Get SLUDGEMAW in Borderlands 4 and Farm His Legendary Drops

This legendary farming guide is geared towards the special process of Getting SLUDGEMAW in Borderlands 4, a highly sought-after boss who has three different and lethal legendary items. Vault Hunters must finish the main story campaign to unlock all the prerequisites before attempting this farm. The initial encounter of Sludgmaw is gated behind two specific side missions.
Requirements: Unleashing the SLUDGEMAW Encounter
Before entering the boss encounter, you'll have to complete and get two back-to-back side quests in the Launchpad zone.
Mission Chain Overview

You must have fully completed playing through the Keep Better Man main campaign before the following missions become available:
"Null and Void": It's the first mission, located in the south of the Launchpad zone.
"All Charged Up": The quest is automatically acquired from the NPC Rhods after the completion of "Know and Void."
Sludgmaw's boss fight is at the conclusion of the "All Charged Up" quest.
Locating the SLUDGEMAW in Borderlands 4

Sludgmaw's location is highly visible on the map, slightly north of the Sundried Rise fast travel node.
To get to the SLUDGEMAW in Borderlands 4, head to Sundried Rise and proceed to the platform where you plummet below the save point.
Dash through the enemies in the outer area to the interior door. Go down the path with the arrows, take the elevator, and fall through the holes until you reach the final Maxi-Response (New-U) station.
Critical Step: Always power up the Maxi-Response machine before entering the arena in order to have the fastest possible reset route.
SLUDGEMAW Legendary Loot Breakdown
Sludgmaw is probably the most effective boss to farm because all three of his unique drops are feasible or even best-in-slot (BiS) for various builds.
The Birt's Bees SMG

This Legendary Submachine Gun (SMG) is an all-around good gun that is notable for its strange projectile behavior.
Damage Type: Comes in all elemental types (Fire, Corrosive, Shock, Cryo, Radiation) and a Kinetic (non-elemental) version.
Weapon Stats: Extremely high fire rate (approximately 14.4 shots/sec) and decent base damage.
Special Effect: "Sends unpredictable projectiles that seek out targets." This provides excellent tracking on targets with minimal player aiming needed.
Red Text: "Fill your life with laughter and bees."
The Onion Shield (Jacobs Shield)

One of the most useful defensive barriers to roll consistently providing utility and survivability.
Core Mechanic: Upon taking an Armor Segment Break, the character is immune to damage for two seconds.
Best Roll: A shield rolled with four armor segments provides four different chances at two seconds of invulnerability, so one of the safest shields to use when blocking large, prolonged bursts of incoming damage.
Stat Bonus: Spunky provides a 30% damage bonus stacking with the amount of shattered armor segments, encouraging aggressive play.
The KickBaller Shotgun (Maliwan Shotgun)

The Kick-Baller is an upper-tier Maliwan shotgun prized for its elemental utility and destructive alternate fire mode.
Elemental Focus: This weapon never falls in the Kinetic element; it always falls with two elements (like Radiation/Shock, Corrosive/Fire). This enhances elemental pairing in Mayhem levels very much.
Alt-Fire: The secondary fire mode shoots a bouncing energy disc that deals sustained splash damage, making it awesome for clearing groups and applying status.
Manufacturer Synergy: Rolled with a C.O.V. Barrel, the charge-up time is decreased for the first time, but then more overall output is given after the first disc fires.
Reset Routine and Optimized Farming
SLUDGEMAW in Borderlands 4 is farmed very easily due to its almost respawning point. The loop is amongst the fastest legend farms in the game due to the quality of the drops.
Quickest Reset Path
After killing Sludgmaw and collecting the loot, exit the arena via the grapple point at the rear.
Teleport to the upper level via the Portal.
Drop down straight away to the lowest level where the Maxi-Response station is located.
Respawn the boss using the Maxi-Response machine.
Replenish ammo or unload unwanted items at the nearby Vending Machines before engaging once more.
This cycle cuts down on travel time and continues to try maxing the attempts to Get SLUDGEMAW in Borderlands 4 to drop the legendary gun or shield with the best parts.
