Solve the tricky Waterstop Evocarium in Borderlands 4! Complete guide to all three orb locations including the hidden underground path.
Understanding Evocarium Mechanics
Evocaria represent one of Borderlands 4’s most rewarding collectible types, combining puzzle-solving with substantial progression rewards. Unlike passive collectibles such as Vault Symbols and Dead Bolts, Evocaria require active problem-solving to unlock their contents, making successful completion particularly satisfying.
The Waterstop Evocarium stands out as one of the more challenging examples due to its hidden underground component, testing players’ observation skills and willingness to explore beyond obvious solutions.

Waterstop Evocarium Overview
Location: Waterstop Point of Interest (POI) Difficulty: Moderate – features one hidden orb location Reward Value: 15 SDU Tokens plus Nyriad lore content Completion Time: 3-5 minutes with proper guidance
The challenge of this particular Evocarium lies not in complex mechanics but in locating the third orb, which requires discovering a concealed entrance that many players overlook during initial exploration.
Complete Orb Location Walkthrough
Orbs 1 & 2: Rooftop Locations
General Area: Rooftops surrounding the Evocarium structure Accessibility: Requires basic jumping and roof navigation Visibility: Both orbs are clearly visible once you gain elevation
Navigation Strategy:
- Identify nearby buildings with accessible rooftops around the Evocarium
- Use jumping and climbing to reach elevated positions
- Scan rooftop areas systematically for golden orb indicators
- Interact with both visible orbs before proceeding to the hidden location
Strategic Note: Complete the obvious orbs first to eliminate them from consideration and focus entirely on locating the hidden third orb.
Orb 3: Hidden Underground Location
Key Landmark: Chimney-like structure with a rooftop orb Search Area: Ground level near machinery, close to the chimney structure Hidden Element: Concealed entrance requiring careful observation
Detailed Location Process:
- Locate the chimney-like structure that has one of the rooftop orbs
- Return to ground level near this landmark structure
- Examine the area around machinery on the floor level
- Look for environmental inconsistencies indicating a hidden pathway
- Find the concealed entrance near the machinery
- Drop down through the hidden access point
- Enter the doorway revealed by the descent
- Navigate to the end of the underground room to find the final orb
Environmental Clues for Hidden Areas
Visual Indicators: Look for gaps, unusual lighting, or architectural inconsistencies Machinery Context: Industrial equipment often masks secret entrances in Borderlands games Elevation Changes: Hidden paths frequently involve vertical movement (up or down)
