Discover how to unearth the 3 arches of Borderlands 4 scattered across the 3 main regions of Kairos, including the locations of all the key fragments, as well as how to find the arches themselves.
The Caves of Auguries are not the only hidden areas in Borderlands 4 worth exploring; there are also the key fragments and their corresponding arenas, culminating in yet another unique boss battle. In this comprehensive guide, we will cover where to find the key fragments, the arches themselves, and how to locate them on your own, if you prefer to avoid guide assistance.
Finding the Key Fragments and the Arches
If you do not want to rely on a guide, it’s relatively straightforward to locate the key fragments and the arches yourself. To get a general idea of the fragments’ locations, you will need to complete silos, which are marked on the map of Kairos. From there, a classic hot-and-cold system kicks in: head towards the designated area and adjust your direction based on the number of bars shown on the right side of your screen. The same system will apply when it comes time to track down the arch after collecting the 3 fragments from a region.
Locations of All Key Fragments
Versant
- Southwest of the region
- Center of the region
- East of the region
Cascadia Burn
- North of the region
- Northwest of the region
- South of the region
Terminus Mountains
- Center of the region
- Northwest of the region
- Northeast of the region
Locations of All Arches
Versant
- At the summit of the mountain indicated on the map below. There shouldn’t be any dangers or tricky platforming phases preventing you from reaching this Arch.
Cascadia Burn
- Head southwest of the city in the region; you shouldn’t have to search for long, as it’s easily accessible without any tricky platforming challenges or specific arenas.
Terminus Mountains
- Go near the Sanctuary of Auguries marked on the map below and enter the cave to the west of your position. Then simply glide down to it to discover the Arch in the area.
Rewards from the Arches
The arches offer a series of intense combat arenas featuring a significant boss at the end. What does that mean? Well, it means good loot awaits! If you’re lucky, that is. Completing these instances will also reward you with substantial amounts of cash and eridium, so it would be wise not to miss out. Lastly, we recommend tackling them in multiplayer to maximize your chances of survival.
