How to Farm Bosses

Find Moxxi's Big Encore in Any Completed Boss Arena

Borderlands 4 - Moxxi
Once players have beaten a boss in Borderlands 4, they can head back to that boss’s arena to find Moxxi’s Big Encore station. This makes every cleared arena a permanent farming location letting you revisit the arena.

Tip: Loot scales with your level. You can farm the first boss grab stronger gear and boost your early game progression.

Farm the First Boss: Splashzone

Borderlands 4 - First Boss Location
You can find Splashzone’s arena in the bottom right corner of the map, making it a consistent and easy farming spot.

Splashzone is relatively easy compared to later bosses, making it a fast and reliable way to grind for early game legendary weapons, shields, and mods.

Spawn Bosses By Paying with Cash

Interacting with the station costs Cash. It instantly respawns the boss and let players replay the boss fight. This system replaces the old method of quitting to the main menu and reloading, allowing for smooth farming.

Costs Increase WIth Each Level Up

Borderlands 4 - Level 10 Moxxi

The Cash cost of using Moxxi’s Big Encore increases as your Vault Hunter levels up, so farming bosses gets more expensive the further you progress. The price appears to be 600 times your current level.

What to Spend Money On

Unlock Weekly Big Encores in Postgame

Moxxi Encore Cash Eridium

After completing the campaign for the first time, Big Encores will become available. These give more drops compared to normal Encores, making it easier to grind for Legendary weapons. Note that these cost Eridium instead of cash and is only available for the weekly boss.

Repeatable Boss Encounters

Moxxi's Big Encore allows you to rematch any boss that you've defeated in main missions and side missions.

Fight Big Encore Bosses Weekly in Endgame

Moxxi
Every week, one boss is chosen as the Weekly Big Encore Boss. They will be a tougher version of the standard boss fight with added modifiers, making them more difficult but highly rewarding battles. To access these, you must complete the Ultimate Vault Hunter Mission: Big Encore mission given after completing the campaign.

What is Ultimate Vault Hunter?

Pay With Cash or Eridium

To rematch bosses, you'll need to pay Cash to respawn the boss. However, this can easily be offset by selling unwanted drops as junk. After beating the game, you'll have access to the Weekly Big Encore version, which will require Eridium instead.
