Eridium and Vault keys
Collect Terminus Range Vault Key Fragments
The three Terminus Range fragments create the key that opens the region’s Primordial Vault.
WHERE & HOW TO FARM
Collect Terminus Range Vault Key Fragments
Cuspid Climb, The Low Leys and Windspear in Terminus Range.
Before you go
- Unlock Terminus Range and the relevant fast travel points.
- Have glide and grapple movement available for the exposed ledge routes.
- Be prepared to enter an Order base for the Windspear fragment.
Farming steps
- Fast travel to The Reliquary and travel to the cliff area west of the Cuspid Climb marker.
- Glide across to the projecting mountain plateau and enter the cave tunnel.
- Follow the cave to the fragment and collect it.
- Travel to Snowy Wells near The Low Leys and climb the rocky path beside the street.
- Use the grapple point at the upper ledge and collect the fragment.
- Go to Windspear and enter the Order base.
- Search the computer room table for the final piece, then use the revealed map marker when ready to enter the Vault.
- The Cuspid Climb route requires a glide to the mountain plateau; start from a high cliff position rather than searching only at the marker.
- Collect all three pieces before traveling to the regional Vault entrance in The Low Leys.
Repeat, collect and use
One-time collection of three regional fragments. The key unlocks the Vault; the fragments themselves are not farmable drops.
Common mistakes
- Trying to reach Cuspid Climb from below: approach from the cliffs and glide to the plateau.
- Stopping at the first ledge in The Low Leys: continue up the rocky path and grapple to the upper shelf.
- Searching outside the Windspear base only: the piece is inside, on a table in the computer room.
When to stop or switch
Stop once the Terminus Range Vault icon appears. Use the key when you are ready to clear the Guardian fight and claim the permanent power-up.
