Three Carcadia Burn fragments form the key to its Primordial Vault and Guardian encounter.
PC / Global, current through weekly rotation October 22–29, 2026
WHERE & HOW TO FARM
Where to farm
Ruined Sumplands, Tonnage Peel and Lopside in Carcadia Burn.
Collect the fragments from Ruined Sumplands, Tonnage Peel and Lopside to reveal the Carcadia Burn Vault. This is permanent regional progression: the pieces are not renewable, but the Vault’s Guardian provides a permanent power-up and XP. Once the key is assembled, the map reveals where to spend it.
Have access to the grapple ability for the Tonnage Peel and Lopside routes.
Complete nearby objectives if a fragment trace is not visible on your map.
Travel to Ruined Sumplands and find the fragment beside the water at the base of the hill.
Collect the fragment from the exposed location among the rocks.
Fast travel to Site Unseen in Tonnage Peel and enter the shipwreck tunnel.
Locate the floor grate in the tunnel, grapple it open and drop into the passage below.
Follow the hidden tunnel and collect the fragment.
Travel to the Lopside fuel station and grapple onto its roof.
Take the fragment from the crate on the roof; then follow the revealed map marker to the Vault when ready.
Farming tips
Judgement’s Lapse and Site Unseen silos, plus Makeshift Chalet, are convenient regional starting points for this collection route.
Scan the tunnel floor if the Tonnage Peel grate is hard to spot; it is a break in the route rather than a visible doorway.
Repeat, collect and use
One-time set of three collectibles and one regional key. The fragments do not respawn as a farm; the Vault encounter can be replayed for activity rewards and XP.
Common mistakes
Driving past the Tonnage Peel floor grate: stop inside the shipwreck tunnel and check the floor before continuing.
Looking for the Lopside piece at ground level: climb to the fuel station roof and inspect its crate.
Assuming an incomplete set opens the Vault: collect all three pieces and confirm the icon appears first.
When to stop or switch
Stop collecting once the Carcadia Burn Vault icon appears. Use the key when ready for the Guardian challenge and its permanent power-up.
