- "This is Tannis. I was digging in the Dahl Headlands, and came very close to uncovering an Elemental Artifact, most likely from the Vault. I was forced to abandon the dig when my brain-dead team quit. They said they saw ghosts, or Bigfoot, or something. If you're someone who isn't a superstitious dolt, I invite you to recover the artifact for yourself. Here's the freight lift code so you can access the site."
- Visit the Haunted Excavation and recover the Elemental Artifact.
- Elemental Artifact found
This mission takes place inside the mountain in the middle of the Dahl Headlands. The subterranean chambers must be accessed by way of an elevator that is guarded by several bandits aboveground at the top, as well as several more near the bottom who are retreating from some "ghosts" when the elevator reaches the bottom. A weapons and health vendor is also here, allowing you to restore lost health if you need to.
Venturing into the passage takes one past some grisly bandit corpses to an expansive cavern with two large statues in the middle. When approached, the statues start to turn, at which point a Guardian Spectre and two Guardian Wraiths will spawn and attack. They have powerful shields but are not particularly high in health, so using shock elemental damage on them is very effective. Upon killing the Guardian Spectre, it will drop a weapon, grenade mod, shields or a random level 2 Eridian artifact.
The mission is turned in at the far end of the cavern and rewarded with a new level 2 explosive artifact.
- "You have discovered the Elemental Artifact which Tannis spoke of. She won't mind if you keep it for yourself, right?"
- A nearby Red Weapon Chest serves to further the rewards in this area.
- If the chest is of no importance, it is possible to simply sprint over to the artifact, complete the mission, and run out again without having to fight the guardians.
- The corpses in the room seem to be that of two Bandit Raiders and one Badass Bruiser.
- Sometimes, running out of the room after the fight starts and running down the hall a few meters causes the two wraiths to disappear, reducing the fight to a single guardian opponent.
- Group of two or more adventurers can cause additional Guardian Wraith to spawn.
- While taking the elevator down, jumping off mid-way into the supports then going to the one diagonally opposite of the two safes, shooting will cause bandits below to spawn and retreat from the dig site and out onto the elevator. If any Psycho spawns in the group, they will not move until the adventurer jumps down.
- It is possible to lure the guardians out onto the surface from the elevator. Simply let them get close, and activate the elevator. Upon moving off the elevator they will usually get stuck, allowing for easy kills. If done correctly, it is possible to make them aggressively tolerant (about to attack, but will not due to distance). The Guardian must not move after a few seconds in order for this to happen.
