Lost Capsule

The Lost Capsule is a long, bulky device that has to be carried back to a safehouse of your choosing – preferably the nearest one to put it in the Decryption Machine there. There is one Lost Capsule at Tonnage Peel.

1 – Northern Queen’s Cradle

The Lost Capsule is sitting on a hill just north of Queen’s Cradle, surrounded by some car wrecks and a small camp. To deliver it to the Safehouse: The Lowrise Decryptor, you’ll face a bit of a challenge – you can’t grapple or climb while carrying it, so you’ll need to toss it ahead as you go. Don’t worry if you lose it, though; the Lost Capsule will respawn at its original spot.

Propaganda Speaker

Evocarium

You’ll find two Evocariums at Tonnage Peel: one’s right at The Lowrise Safehouse, and the other is just south of it, by the toxic pool.

1 – Eridian: Meaning – The Lowrise

You’ll find the Eridian Evocarium torch in the valley below the Lowrise Safehouse. Head to the Ripper settlement on the ground floor, and you’ll see the torch sitting on a metal structure inside.

 Evocarium Torch map   Tonnage Peel   Kairos   Borderlands 4 | camzillasmomcom
 Evocarium Torch   Tonnage Peel   Kairos   Borderlands 4 | camzillasmomcom

Okay, so as always, you need to find the three glowing yellow orbs and touch them to grab the Eridian ECHO Log at the torch. The first one I went for is right in the south, on the same level as the torch. It’s annoying, but it’s perched on top of a super-narrow beam. You’ll want to jump over from the ruins just below it and aim for the back wall to land safely and snag it.

 Evocarium Orb 1   Tonnage Peel   Kairos   Borderlands 4 | camzillasmomcom
 Evocarium Orb 2   Tonnage Peel   Kairos   Borderlands 4 | camzillasmomcom

You’ll find the second orb by the purple light to the west, just above you. To get there, jump over and grab the ladder on the orb’s platform.

 Evocarium Orb 2 close with ladder   Tonnage Peel   Kairos   Borderlands 4 | camzillasmomcom

Alright, the third and final orb is perched on top of a building to the north. You’ll spot a strong wind vent right below it. Use that to boost yourself up to the platform where that radioactive canister is. From there, it’s a quick climb to snag the orb. Once you have it, head back to the Eridian torch for your prize: ECHO Log Eridian: Meaning.

2 – Eridian: Life – Southern Toxic Pool

Alright, the second Eridian Evocarium is just chilling by the southern toxic pool on the Tonnage Peel map. Give it a tap, and it’ll pop out those three glowing orbs.

 Evocarium Toxic Pool map   Tonnage Peel   Kairos   Borderlands 4 | camzillasmomcom
 Evocarium Toxic Pool Location   Tonnage Peel   Kairos   Borderlands 4 | camzillasmomcom

Just like before, you’ll need to find and touch three glowing yellow orbs to get the Eridian ECHO Log at the torch. The first one is easy to spot from the torch – it’s just to the south on a ledge. Look for a red flag with a grapple point above it to get up there.

 Evocarium Toxic Pool Orb 1 far   Tonnage Peel   Kairos   Borderlands 4 | camzillasmomcom

Vault Fragment

You’ll find the Vault Fragment deep underground in the Wreck of the Last Great Hope. There’s a tunnel/corridor packed with creeper nests, and you can also snag an ECHO Log Collectible in there. Just keep an eye out for a vent cover on the floor that you can pull off.
