The cave entrance is a vertical, underwater shaft, located in the lake at (55.2, 65.9). The shaft is just large enough for a Rock Drake to fit through and there is space to park 3-4 drakes once through the tunnel. You won't be able to take the drake far into the cave system, but it's a convenient way to get there.

There are a number of vertical cliff climbs in this cave that you will need to traverse to get to the artifact, which can be overcome with Climbing Pick (Aberration) Climbing Pick (Aberration) and/or Zip-Line Anchor (Aberration) Zip-Line Anchor (Aberration) (don't forget Zip-Line Motor Attachment (Aberration) Zip-Line Motor Attachment (Aberration) to get back out)

There are also several longer underwater tunnels, full of aggressive creatures. It is suggested to take multiple SCUBA Armor SCUBA Armor, Harpoon Launcher Harpoon Launcher and plenty of Spear Bolt Spear Bolt or other ranged weapon (e.g. Crossbow Crossbow) that can be fired underwater, is recommended over melee weapons due to the presence of Electrophorus Electrophorus, Cnidaria Cnidaria, and Baryonyx Baryonyx.

Bring a campfire with some wood when traveling through the cave; it is extremely likely you will be lamprey'd in the underwater tunnel, making you a target for the swarm of seekers that surround the artifact. Keep your wits about you in case of an earthquake; if climbing out of the water, time your movements so you don't fall back into the water.

Retrieving the Artifact[]

The artifact is located approximately at (50.5, 72.6).

There are two routes to reach it, and by far the easiest, most straightforward one is going through the underwater passage located at the bottom side room from the main chamber. The journey includes one time of surfacing, then dive forward again to reach the artifact chamber.

Very Rare[]



  • It is possible to place structures in many places throughout the cave (clipping disabled)
  • By virtue of the difficulty to reach and obtain the artifact, this cave is the most difficult to traverse. The Elemental Vault can easily be navigated with a Rock Drake with minimal conflict required and the Old Railway Cave is simply easier. While you can tame creatures further within the cave such as Baryonyx and Sarcos that can help with the aquatic sections, this cave is still difficult to successfully complete.
  • Though HIGHLY unrecommended, it is indeed possible to raise a Rock Drake inside the cave, due to being able to tame creatures inside the cave, specifically because of Dimetrodons with their insulation mechanic, however, it will not be able to exit the cave. You have been warned.
    • This can be mitigated with Cryopod (Extinction) Cryopod (Extinction). Be wary of where you release it however, as even though it can withstand (but is not immune to) Electrophorus electric stun attack enough to avoid knocking the rider off the saddle, groups of them can kill the drake easily.
