Borderlands 4 has 18 Evocariums with 18 Eridium ECHO Logs. You first have to find the Evocarium, an Eridium device, and interact with it. Three beams will then point to the location of three orbs. Collect those orbs and return to the Evocarim to receive an Eridium ECHO Log. Collecting all 18 Eridium ECHO Logs will unlock the challenge “Stranded Sister.”

All Evocariums – Overview Map
All Evocariums are highlighted in the overview map below.
The Fadefields
1 – Eridian: Paradise
The Evocarium is in the southern part of Harper’s Hideaway at the silo in the northeast of the Coastal Bonescape region.
Interact with the Evocarium to reveal the three target orbs. One is on top of the barn, where Byron is. The second orb is on the center building opposite the barn, and the third is in the northwest.
You can easily climb the barn by getting on top of the silos and then landing on the nearby cages to climb up to the first orb.
Then, head over to the building opposite the barn and climb the blue silo next to it.
From the second building, you can also see the last orb. It’s at the tallest silo of the farm. After picking up the third orb, return to the torch and interact with it. This will give you the ECHO Log Eridian: Paradise.
2 – Eridian: Lost
Waterstop is an outpost in the east of the Coastal Bonescape. In the center of it is the Evocarium.
Use the torch to reveal three target orbs. One is on top of a small white water tank, the second one is on the round roof, and the third is below the building to the west. Reach all three targets to receive the ECHO Log.
The water tank orb can be accessed from the higher, northwestern side of the Waterstop.
The round roof can be reached from the previous orb. Just jump and glide across to reach the round roof.
For the last orb, look for a crawlspace with a ladder below the northeastern building. Down here, you can find the third orb. Collect the third orb and return to the Evocarium to unlock and reveal the ECHO Log Eridian: Lost.
3 – Eridian: Survival
The only Evocarium in The Howl can only be reached by following the “Savage Salvage” Side Mission into a cave full of Rippers, where a person is trapped inside an orb hanging from the ceiling. The Evocarium is in this cave. Interact with it to reveal the location of the three glowing orbs.
One beam goes southeast, while the other two go towards the east.
For the first Orb, stay on the same level as the torch and cross over towards the east, then cross the bridge to find the orb in front of a hut. You can see the bridge that you have to cross in the center right of the above screenshot.
Return to the other side by crossing the bridge. The second orb is hiding in the hut ahead.
The third Orb is in the open cave section of the cave. From the previous hut, turn right towards the open cave, where you can see the orb on the platform below. Return to the Eridian device, and interact with it to receive the ECHO Log Eridian – Survival
4 – Eridian: Empty
Operant Control is an Order Checkpoint south of Horace’s Oversight in the south of the Hungering Plain. The Evocarium is on the roof. There is a grapple point you can use to get up there.
Use the torch to reveal three target orbs. One is on the tall tank just ahead of the torch, the second one is on top of the silo, and the third one is on the roof of the command Center.
For the orb on the tank ahead, you can jump and glide across right from the Evocarium torch.
Then, glide back to the torch and use the height with a double jump and glide to reach the ladder of the silo so that you can get the orb.
Glide back to the roof of the torch. From there you can double-jump and glide to the roof ot the other building. There is a small platform you can land on at the side of the roof. From there, walk the narrow rim to the left, where you can jump up to the roof to get the orb. Return to the torch to receive the ECHO Log Eridian: Empty.
5 – Eridian: Warmth
You’ll find the Evocarium at Tetanus Squad, way out west in the Idolator’s Noose region. It is right in the middle of the area, down in the ditch. Grab it to reveal three target orbs. There’s one on each building.
Check out these screenshots of the orbs on all three buildings. Just use ECHO to spot the ladders and climb up using the surroundings! Once you’re done, head back to the torch to grab the ECHO Log Eridian: Warmth.
6 – Eridian: Veil
The Evocarium is at the top level of a ripper settlement, just Zadra’s Backup Plan hideout in the Dissected Plateau region.
One of the orbs is on top of a hut in the southeast.
From the Evocarium, look to the northwest, and you will see another orb on the roof of a hut.
The third orb is in the northeast with the Evocarium behind you. Return to the torch to receive the ECHO Log Eridian: Veil.
Carcadia Burn
7 – Eridian: Hungrier
This time, the Evocarium is northwest of the Yawning Yard in the Lopside region, standing out in the open without the protection of buildings. Interact with it to reveal the tree orbs.
The orbs are located on top of a steep rock just above the torch, on top of a nearby building, and on top of a turbine in the east. The only tricky one is the orb on the turbine. I reached it by gliding from the elevated rock, where one of the orbs is. In the screenshot below, you can also see the turbine orb behind the orb on the elevated rock. Once you’re done, head back to the torch to grab the ECHO Log Eridian: Hungrier.
8 – Eridian: Life
The first Evocarium in the Tonnage Peel region is located near the southern toxic pool on the Tonnage Peel map. Tap it, and it will release three glowing orbs.
The first orb is easy to find – head south from the Evocarium, where you’ll see it on a ledge. Look for a red flag with a grapple point above it to climb up.
You’ll find the second orb just next to the toxic pool.
The third and final orb is a bit west of the second one, sitting on a metal structure. Just grapple up to it. After that, head back to the Eridian torch to grab: ECHO Log Eridian: Life.
9 – Eridian: Meaning
The second Evocarium at Tonnage Peel is 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.
The first Orb I went for is located in the south, at the same level as the torch. It’s a bit tricky to grab since it’s sitting on a very narrow beam. To get it, jump over from the ruins just below and aim for the back wall to land safely and collect it.
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.
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 for the ECHO Log Eridian: Meaning.
10 – Eridian: Metal
You can find an Evocarium in Ruined Sumplands. It’s located in the center courtyard of the Pain Street POI, just northwest of the Faction Town. Interact with it, and three target orbs will appear.
From the torch, you’ll only see one orb. It’s up on the building right next to you. To get to it, use the grapple point at the back of the building. Oh, and the ECHO Log Collectible: Fashionista is up there, too!
From the first Orb’s spot, you can actually see the second one. Just peek northwest, and you’ll catch it behind that toxic waterfall.
You can actually see the third Orb from where the first one was. Just look west, and you’ll spot it right on top of the building. To grab it, you’ll need to climb up from the other side. There’s a small ladder that’ll get you to the top. Once you’ve got all the orbs, head back to the torch to snag your Eridian ECHO Log: Metal.
Dominion
11 – Eridian: Power
The Evocarium is in the south at the bottom of the yellow waste pit of the Carcadia District.
The first orb is just north of the Evocarium.
The second orb is on top of the building. You can climb it by using the vertical wind shaft at the back of it.
The last one is on top of a pipe in the south. Glide over there from the building. Collect all three orbs and return to the Evocarium to receive Eridian: Power.
12 – Eridian: Scars
The Evocarium is just northwest of the Fades District Safehouse, overlooking the swamp below.
The first orb is on a small terrace with a radio in the southwest.
The second orb is in the northwest, on top of the building under the tarp roof. This building has a grapple point that takes you right to where the orb is.
The last one is hanging off the crane in the north. You can access it from the previous orb’s location. Collect all three orbs and return to the Evocarium to receive Eridian: Scars.
13 – Eridian: Failure
The Evocarium is in the south of the Terminus District, by the water.
The first orb is on the round island when looking to the northwest.
The second one is high up on the platform to the southeast. Use the climbable wall in the southwest to reach it.
The last one is on top of a small platform with a door to the south. There is a grapple point you can use to glide over to get it. Collect all three orbs and return to the Evocarium to receive Eridian: Failure.
Terminus Range
14 – Eridian: Rebounding
The Evocarium is by the river, just west of Substation Canonary in the northern parts of the Stoneblood Forest.
After interacting with it, the three orbs will appear. All of them are visible from the Evocarium device. Two of them are on top of the nearby buildings, one of them on top of one of the wildlife burrow spawn points. Return to the Evocarium to pick up the collectible ECHO Log.
15 – Eridian: Gold
The first Evocarium in the Low Leys region is just south of the Order Silo: Deathright, near a Kratch nest.
All three Orbs are visible from the Evocarium if you look to the northwest. Interact with all three orbs and return to the Evocarium to receive the Eridian ECHO Log.
16 – Eridian: Thundercloud
The second Evocarium in the Low Leys is just west of Checkpoint Taupe in the valley. Interact with it to reveal the three orbs.
All three Orbs are visible from the Evocarium if you look to the southwest. Interact with all three orbs and return to the Evocarium to receive the Eridian ECHO Log.
17 – Eridian: Shadows
The Evocarium is in the northwest of Cuspid Climb, north of the Cloundbank POI. It’s in the center of a settlement occupied by the Order. Interact with it to reveal the three orbs.
One of them is on top of the building just north of the Evocarium. You can jump up the ledges and balconies to reach it.
The second Orb is on top of the tower at the other side of the road. There is a climbable wall with a grapple to reach it.
The third Orb is on a ledge just south of the Evocarium. Return to the Evocarium after having collected all three orbs to receive the Eridian ECHO Log collectible.
18 – Eridian: Gift
The second Evocarium at Cuspid Climb is in the south, at the Hollowhome Point of Interest – a ripper settlement. Interact with it to reveal the three orbs.
For the first one, look to the east to find it on one of the roofs. You can just glide over to reach it.
The second Orb is on the roof of the shrine in the south. Get up to the bridge above of the Evocarium to reach this orb.
The third Orb is on top of the tower in the northeast. Reach the very top of the area and glide down to get it. Return to the Evocarium after having collected all three orbs to receive the Eridian ECHO Log collectible.
