What to know

  • The Oppressor is encountered during the main mission A Lot to Process in The Killing Floors, Fadefields.
  • You can farm it repeatedly via Moxxi’s Big Encore machine after the mission.
  • Its weaknesses are Shock and Corrosive damage types.
  • The boss uses heavy bombardment attacks that can overwhelm unprepared players.

After you first encounter The Oppressor in the story, you’ll likely want to return to farm its loot. Here’s everything you need to know, from finding it to beating it and what it drops.

How to get to the Oppressor

The Oppressor appears in The Killing Floors, an area within Dissected Plateau, Fadefields. You’ll fight it first during the mission A Lot to Process.

Once you’ve cleared the story fight, use Moxxi’s Big Encore machine located near the arena’s entrance to replay the battle anytime. This is the key farming method, letting you re-engage the boss without replaying the entire mission.

How to defeat the Oppressor

The Oppressor is a large mechanical enemy that relies on missile barrages, projectile spreads, and area carpet bombing. To handle the fight effectively:

Step #1

Equip weapons that deal Shock or Corrosive damage. These hit its armored body hard.

Step #2

Use cover actively. Its missile spreads can wipe your shields fast if you’re in the open.

Step #3

Prioritize hitting weak points. Snipers or scoped weapons allow you to stagger it quickly.

Step #4

Keep moving between bombardments. The carpet-bomb zones mark before impact—dodge them by staying mobile.

Step #5

If farming, focus on killing quickly rather than conserving ammo. The faster you clear the fight, the quicker you can repeat for loot.

Wrapping on the Oppressor’s loot

Fighting the Oppressor is both a story milestone and a reliable farming route in Borderlands 4. Once unlocked, it's replayed via Moxxi’s Big Encore machine, making it one of the easier legendaries to grind. The boss’s loot pool—Asher’s Rise, Onslaught, Blood Analyzer, Streamer, and Matador’s Match—offers valuable weapon and gear options, especially for players who lean on high-damage SMGs or sniper builds.
