For a series centred around legendary Vault Hunters, there’s a surprising lack of vault hunting going on. I’m baffled to say that Borderlands 4<\/a> finally changes this, tasking you with finding nine vault key fragments<\/strong> to open three unique vaults hidden across Kairos.<\/p>\n

While some are easy enough to track down, others are a right pain and will have you searching every nook and cranny\u2014even once you’ve unlocked the hint by completing nearby silos. Below, I’ll go over where to find each of the vault key fragments and their respective vaults.<\/p>\n

Since unlocking the silos isn’t actually required to find the fragment they point towards, I’ll cut to the chase for you (aside from the few cases where it’s easier to reach the fragment using the silos’ lift).<\/p>\n

Fadefields vault and fragment locations<\/span><\/h2>\n

The Fadefield is the first area you’ll have access to on Kairos, and it’s a good idea to unlock its vault early on. Here’s where you need to go:<\/p>\n

Coastal Bonescape vault key fragment:<\/strong><\/p>\n

This fragment is on a crate at the base of a tower on the island near the water in Stillshore, in the southwest corner of Coastal Bonescape. This is the first fragment you’re likely to run into after leaving the prologue and helping Claptrap set up shop in the Abandoned Post safehouse, as there’s a bounty contract that leads you to the area.<\/p>\n

The Howl vault key fragment:<\/strong><\/p>\n

This one’s on a pedestal in a small cave on the northeast side of The Launch Pad (but southwest of Ardor’s Bounty). There are odd-shaped pillars nearby, so it’s easy enough to spot if you’re heading north up the main road from the settlement.<\/p>\n

Idolator’s Noose vault key fragment:<\/strong><\/p>\n

Head inside Rosemary’s Reserve to the northeast of Idolator’s Noose until you see the Propaganda Tower. Then, turn southeast and use your grapple to pull the loose vent blocking a hole in the wall, revealing a cosy nook where you’ll find the fragment on the Ripper’s corpse, as well as a Marcus bobblehead while you’re at it.<\/p>\n

Fadefields vault location:<\/strong><\/p>\n

With all three Fadefield vault key fragments, you’re ready to find the Arch of Inceptus vault. This vault is on a cliff to the east of the Fadefields, but you’ll need to grapple up the cliff face and clear the mangler nest first, as this leads to the path up the hill. Completing this vault will reward you with faster glide pack regeneration.<\/p>\n

The Fadefields vault boss is the Primordial Guardian Inceptus, and there are a few things to be on the lookout for:<\/p>\n
