Hidden beneath Fisch’s waters lies the Luminescent Cavern Bestiary, a submerged sanctuary teeming with bioluminescent marine life. Adventurers must journey across scattered islands to obtain three mystical artifacts before descending into Desolate Deep. These relics activate ancient mechanisms near sunken ruins, revealing passages to eight radiant aquatic species:
- Cerulean Mandarinfish
- Crimson Flying Squid
- Glowspark Microbes
- Azure Moray Eel
- Shadowfin Sleeper Shark
- Crown Mantle Jelly
- Static Star Seahorse
- Leviathan Serpent Drake
Before hunting artifacts, navigate to the Crimson Beacon’s underwater monoliths. These weathered platforms indicate which triad of relics (varies per player) unlocks the cavern’s entrance through symbolic engravings.

Accessing the Bioluminescent Realm
- Navigate to Sunstone Island’s eastern reef cluster, marked by a crimson beacon
- Submerge near the corroded anchor chains, following phosphorescent algae trails west
- Locate three stone monoliths engraved with cryptic symbols (variants: turtle/mountain/crescent)
- Match these icons with corresponding relics found across island archipelagos
- Document required items via in-game camera (F2 key) to prevent retrieval errors
- Engage pressure plates at each monolith while holding matching artifacts
- Observe seismic shifts revealing an underwater crevasse beneath the central pillar
- Traverse the crystalline tunnel system, avoiding predatory lumifin schools
Common Inquiries
Cavern’s Unique Features?
This subaquatic gallery contains rare fauna emitting natural light displays through specialized bioluminescent cells. Explorers encounter dynamic ecosystems varying hourly with tidal patterns.
Entry Mechanics Explained
Three randomly assigned relics must be inserted into submerged plinths near thermal vents. Successful alignment triggers geomorphic shifts in the seabed geology.
Identifying Required Artifacts
Each monolith projects holographic glyphs corresponding to specific cultural artifacts. These match relic engravings found in designated island shrines.
