Borderlands 4 (BL4): Moxxi's Big Encore Locations & Interactive Tracking Guide

Moxxi's Big Encore is the Boss respawn system in Borderlands 4. This mechanic allows you to instantly replay Boss encounters to farm specific loot without needing to exit to the main menu and reload the game.

To trigger a rematch, you must interact with the Moxxi's Big Encore vending machine located near the specific boss arena.

Requirement: The machine will only appear after you have defeated that boss for the first time in the campaign.
Cost: You must pay a fee in Money to activate the respawn.

In addition to standard farming, there is a rotating Weekly Big Encore Boss event. This specific boss offers significantly increased drop rates for high-tier gear and legendary loot. Unlike standard respawns, the Weekly Boss requires payment in Eridium.

Locating these machines is important for efficient loot farming. To find the exact spot for every respawn station, check out our full list below, and for a comprehensive view of the region, visit our Borderlands 4 maps.
