Borderlands 2 remains a gold standard in the looter-shooter genre due to its chaotic action, memorable characters, and layered environmental secrets. Among its massive roster of optional content, the mission titled The Lost Treasure stands out as an engaging puzzle that requires exploration rather than pure combat prowess. Vault Hunters looking to complete this unique scavenger hunt must scour hidden corners of Pandora to claim a highly coveted piece of gear.

How to Unlock and Initiate the Hunt

Before you can begin searching for this ancient stash, you must navigate to the volatile region known as Sawtooth Cauldron. The mission becomes available after completing the mainline story quest titled Toil and Trouble in the late stages of the game. Defeating a specific badass enemy in the main facility will trigger the drop of an ECHO recorder that initiates the treasure hunt.

Once the quest is active, your map will guide you toward the massive ash-covered zone of Eridium Blight. The core objective requires you to follow a series of cryptic riddles left behind by a long-dead explorer. These clues point to four distinct map pieces scattered across the treacherous landscape, forcing you to look beyond standard pathways.

Locating the Four Map Clues in Eridium Blight

Finding the first piece requires checking the infrastructure built around the environmental hazards of the zone. You must search the structural pillars located directly underneath the massive, acid-soaked railway bridge spanning the canyon. The clue container is attached tightly to one of these supports and requires careful navigation around the corrosive fluids below.

The second map fragment is hidden near the industrial machinery tucked away in the northern corners of the map. Look for a large warehouse facility surrounded by standard bandit patrols and scrap metal. Clearing the initial defenders allows you to safely check the side walls near the air ducts where the hidden container rests.

For the third piece, players must head toward the rocky outcrops where native wildlife frequently nests. This piece is hidden on top of a towering rock archway that requires a bit of precise platforming to reach successfully. The final map fragment is located near an old extraction pipeline, tucked neatly behind a generator shield that must be bypassed manually.

Solving the Switch Puzzle at Mount Infurnus

With all four pieces securely in your possession, the assembled map directs you to the scorching peak of Mount Infurnus. Inside a small facility overlooking the lava flows, you will discover a console containing four colored switches. Activating these levers in the exact chronological sequence outlined by the riddle text is essential to unlock the final cache area.

Flipping the wrong switch will trigger localized security turrets that can quickly deplete your shields if you are caught unprepared. Pay close attention to the environmental hints regarding the order of operations, focusing on chronological hints rather than random guessing. Once the correct pattern is entered, a nearby elevator lift will activate, granting access to the upper vault room.

Quest Rewards and Weapon Performance Breakdown

Riding the elevator brings you directly to the hidden treasure chest which yields substantial rewards for your meticulous investigation. Alongside a generous amount of experience points and bonus money, the main prize is a unique Dahl pistol called the Dahlminator. This specialized firearm is highly valued for its elemental properties, firing homing corrosive darts that track moving targets automatically.

The tracking projectiles make this weapon incredibly effective against armored Hyperion loaders and flying buzzards that are difficult to hit with standard firearms. Because the darts burst upon contact after a brief delay, it provides excellent sustained damage against stationary bosses. Completing this side activity ensures your arsenal is fully prepared for the challenging endgame encounters waiting on Pandora.
