How to get Birt’s Bees

Step 1: Progress to Fadefields

You need access to the Fadefields area, unlocked by advancing the main story. This is where both Sludgemaw and Idolator’s Noose are located.

Step 2: Play through the Null and Void mission

During the Null and Void mission in Idolator’s Noose, you also have a chance at finding Birt’s Bees. To get access to Sludgemaw, you have to do the quest Null and Void and be all charged up. They link to each other and are found south of the launchpad, and then, after the mission, you'll find the Moxxi sign outside the boss arena to farm him. This makes it a natural checkpoint for farming, since you’re progressing the story anyway.

Step 2: Target Sludgemaw

Find and defeat Sludgemaw, a named boss in the Fadefields. He has a chance to drop Birt’s Bees directly.

Step 4: Use replay mechanics

Once you’ve unlocked it, use Moxxi’s Encore to re-fight Sludgemaw or repeat Null and Void encounters without resetting the entire area.

Step 5: Raise your odds
  • Switch to a higher difficulty.
  • Equip gear that improves loot or drop rates.
  • Make sure your level is close to the enemy level to scale loot properly.
Step 6: Farm until drop

Keep repeating the fights. Legendary drops aren’t guaranteed, but persistence and replay tools make farming more efficient.
