Borderlands 4 (BL4): Vault Hunter's Guide to Kairos Locations & Interactive Tracking Guide

Vault Hunter's Guides to Kairos are the 12 ECHO Log collectibles narrated by Arjay in Borderlands 4 — the Vault Hunter first encountered in the Welcome Center tutorial, whose personal recordings about Kairos's regions, factions, environments, and history are left behind across the planet for other Vault Hunters to find.

Every Guide is tracked at exact coordinates on the Borderlands 4 maps. Collecting all 12 completes the Guided Tour challenge, awarding an exclusive Weapon Cosmetic alongside XP, Eridium, and cash.

What Vault Hunter's Guides to Kairos Are

Each Guide is a small physical amulet — pinned to a wall with a knife, hanging from a tree, attached to a fence, or pressed into a surface across Kairos's camps, ruins, rooftops, and creature-infested areas.

Interacting with one plays a short ECHO monologue from Arjay covering that region's notable characters or environments. Collected Guides are stored in the ECHO Logs section of the inventory and can be replayed at any time.

Unlike Evocariums and Survivalist Caches, Vault Hunter's Guides do not award SDU tokens on pickup.

Their value is lore access and regional completion percentage — plus the Weapon Cosmetic unlocked by the Guided Tour challenge on finding all 12. Each Guide counts toward the area completion percentage of the region it's found in.

How to Spot a Guide

Guides appear as blue icons on the in-game map once you enter proximity — switching to green after collection.

They're small and visually easy to miss against busy environments — look for the distinctive glinting amulet appearance on dark surfaces, rough timber walls, and tree bark. Some hang at eye level; others are low to the ground or pinned at an angle.

If the map icon is present but the Guide isn't immediately visible, check vertically — many are pinned slightly above or below the expected sightline.

The Mission-Gated Guide and Its Shrine Mechanic

The Terminus Range Guide in Cuspid Climb is the only entry in this guide requiring a Side Mission to access.

It is only reachable during or after completing It's a Whole Phase Situation. During that mission, advance until the "Reach Light" objective, proceed through the Mountain Apse area using a newly available grapple point, pass through a Kratch-occupied chamber to reach the tower of light, then look west from the ledge to find the Guide pinned to a tree below.

Additionally, interacting with the shrine at this location and meleeing it awards 10 SDU tokens and additional loot — a unique mechanic specific to this entry not replicated at any other Guide location.
