Lost Capsule – 1

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.

Evocarium – 2

Overview map showing the location of the two Evocarium collectibles in the Tonnage Peel region of Borderlands 4.

1 – Eridian: Meaning
2 – Eridian: Life

-> Also available: Stranded Sister – All 18 Evocariums Revealed

1 – Eridian: Meaning

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 camzillasmom.com
 Evocarium Torch - Tonnage Peel - Kairos - Borderlands 4 camzillasmom.com

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 camzillasmom.com
 Evocarium Orb 2 - Tonnage Peel - Kairos - Borderlands 4 camzillasmom.com

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 far with ladder - Tonnage Peel - Kairos - Borderlands 4 camzillasmom.com
 Evocarium Orb 2 close with ladder - Tonnage Peel - Kairos - Borderlands 4 camzillasmom.com

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

The second Eridian Evocarium is just 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 camzillasmom.com
 Evocarium Toxic Pool Location - Tonnage Peel - Kairos - Borderlands 4 camzillasmom.com

Just like before, you’ll need to find and touch the three glowing yellow orbs to get the Eridian ECHO Log. 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 camzillasmom.com

Vault Fragment – 1

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.

It all began in the ’80s when I was just 7 years old. Starting with basic arcade games, I soon delved into titles like Loom and Monkey Island by Lucasarts. Throughout the years, as I indulged in more and more games, I consistently sought clear guides to swiftly navigate my gameplay. Now, it’s my turn to contribute back to the community.
