The Lost Treasure is one of the most engaging side missions in Borderlands 2, offering Vault Hunters a classic treasure hunt across the dangerous environments of Pandora. Triggered in Sawtooth Cauldron, this quest requires players to decipher clues, collect map fragments, and navigate to the deep subterranean caverns of Caustic Caverns. Understanding each step of this mission ensures you reach the hidden stash efficiently without getting overwhelmed by local wildlife.

Starting the Quest in Sawtooth Cauldron

To begin your search, you must first pick up an ECHO recorder dropped by enemies in Sawtooth Cauldron. This item initiates the mission and tasks you with collecting four distinct map clues scattered across the area. Eliminating the Bandits and Goliath forces in this region will eventually yield all necessary map pieces needed to pinpoint the final treasure chest.

Once all four fragments are acquired, the map directs you away from Sawtooth Cauldron. Your next destination is Caustic Caverns, where the actual chest lies hidden deep within the facility. Preparing proper elemental weapons before entering will make dealing with the local enemies significantly easier.

Navigating Caustic Caverns to Find the Treasure Room

Upon entering Caustic Caverns, follow the quest markers leading toward the central structure. You will need to reach the upper levels by taking the main elevator or navigating around the perimeter hazards. Expect heavy resistance from Varkids, Spiderants, and Threshers along the way.

Clear out the hostile creatures near the top platform to safely interact with the objective. Locate the main switch on the wall or floor to unlock access to the hidden room above. Once activated, an elevator mechanism or door opens to reveal the final loot chamber containing the red chest.

Claiming Your Loot and Mission Rewards

Inside the secret room, interact with the treasure chest to claim your weapons, gear, and Eridium rewards. While the loot drops are randomized based on your current character level, the quest provides solid experience points and Badass Rank challenges upon completion.

Completing this mission fully wraps up one of Pandora's most memorable side adventures. If you enjoy discovering hidden areas and completing tricky side objectives, taking the time to finish The Lost Treasure is well worth the effort.
