The Demon in the Dark is a memorable side quest in Borderlands 3 that combines action with a distinct nod to classic fantasy lore. Located deep within the desolate wastes of Pandora, this mission tasks Vault Hunters with investigating a mysterious underground disturbance. Players who venture into these depths will uncover hidden ruins, solve puzzle elements, and face unique enemy types along the way.
How to Find and Start the Quest
To begin this side mission, you must travel to Konrad's Hold on the planet Pandora. Look for a bounty notice posted on a wall near the center of the map area. Interacting with this exclamation point icon will formally add the objective to your active quest log.
Once accepted, your map will guide you toward an isolated cavern entrance buried beneath the industrial machinery. Following the path leads down into a forgotten subterranean network known as the Burnham Springs. Here, you will encounter an eccentric robot named Wren who serves as your main guide for the narrative.
Navigating the Underground Ruins
Wren requires assistance exploring the ruins and requests that you clear out dangerous local fauna. The area is heavily populated by various forms of Varkids that will attack in aggressive waves. Managing these elemental variants carefully is essential to keeping your shields active while pushing forward.
As you progress deeper, the environment shifts to reflect ancient, abandoned architecture hidden beneath the desert crust. You will need to locate hidden switches and clear specific blocked pathways to allow Wren to continue forward. Staying close to your robotic companion ensures you do not trigger additional traps unnecessarily.
Solving the Three Rune Puzzles
The central progression bottleneck involves aligning a series of magical runes scattered across a large stone chamber. Wren will provide vocal cues highlighting which specific targets need to be shot in order to proceed. Paying close attention to the glowing symbols on the walls reveals the correct order of operations.
If you fail the sequence, additional waves of enemies will spawn to disrupt your puzzle-solving efforts. Taking your time to identify the matching symbols ensures a smooth transition to the final chamber. Successfully activating all three pillars unseals the grand gateway ahead.
Defeating the Final Boss and Collecting Rewards
Behind the gateway lies the primary threat of the cavern, a powerful unique creature named Lagamar. This boss features high health pools and destructive area-of-effect attacks that can quickly drain your health. Utilizing mobile combat tactics and keeping your distance will help minimize incoming projectile damage.
After defeating the creature, return to Wren to conclude the exploration contract. The primary reward for completing this mission is the unique legendary shotgun known as the Burning Chomper. This weapon fires unique vertical lines of fire, making it an excellent addition to your combat arsenal.
