BL4 Waterstop Evocarium puzzle location: How to start the puzzle

The puzzle sits at the Waterstop point of interest in Coastal Bonescape, located to the east of the initial base and northeast of the Splashzone boss area.

This area is filled with enemies, mainly the Timekeeper's minions, who patrol the northern parts, so securing the area first is crucial. The puzzle initiation comes from interacting with a device found near the southwestern part of the Waterstop area.

This device activates the orb locations, highlighting the three required Memordium orbs around the vicinity.

Where to find the three Memordium orbs at Waterstop

First orb: 

Located northeast from the device, this orb sits atop a large building’s roof on the left side, marked by a beam of light. Players need to climb or use grappling points to reach it.

Second orb: 

Also visible northeast and across from the first, the second orb is positioned on the roof of another building to the right. Using double jumps and gliding can help reach this orb.

Third orb: 

This one is trickier to find. From the device, head northwest past one pit to a second pit area with extensive piping and machinery. Jump across the pipes and look for a ladder descending under the floor. The secret room at the base of the ladder contains the third orb and some loot.

How to complete the Waterstop Evocarium puzzle step-by-step

Step 1: Clear the enemies

Eliminate foes patrolling around the Waterstop area to safely explore without interruptions.

Step 2: Interact with the Evocarium device

Find and activate the device near the southwest of Waterstop to reveal the three orb locations.

Step 3: Collect the first two rooftop orbs

Head northeast from the device and climb the rooftops to grab the first two orbs, typically using grappling anchors, double jumps, or gliding.

Step 4: Find and enter the secret underground room

Go northwest past the first pit and jump onto the large pipes by the second pit. Search for the ladder leading down and collect the third orb inside the hidden room.

Step 5: Return to the device

Once all orbs are collected, go back to the Evocarium device and interact with it to complete the puzzle.

Completing this mini-puzzle grants 15 SDU points, increasing inventory space and offering a rewarding challenge early in Borderlands 4.

Unique challenges and tips for Waterstop Evocarium

The main difficulty lies in finding the third orb since its beam of light is less direct. Utilizing observation for environmental markers like pipes and ladders helps locate the secret area quickly. Also, managing enemy threats before starting the puzzle reduces complications. Players can safely glide between rooftops to optimize orb collection timing.

Rewards for solving the Waterstop Evocarium puzzle

Upon returning the orbs to the device, the puzzle completes, offering 15 SDU points. These SDU points expand the player's inventory capacity, which is essential for managing loot and equipment throughout Borderlands 4.

The Waterstop Evocarium is a satisfying mini-puzzle in Borderlands 4. Finding the three orbs requires paying attention to environment, using mobility, and exploring rooftops and ground areas alike. Completing it gives both loot and fills in exploration progress. With patience, it’s a rewarding detour from the main quest.
