Understanding Natlan Oculi and Underground Mechanics
What Are Oculi and Why They Matter
Pyroculus collectibles upgrade Natlan's Statue of the Seven, directly impacting exploration progress and region completion percentage. Each grants 60 Adventure EXP and unlocks rewards including Primogems, Mora, and Natlan Shrine of Depths Keys. Statue progression requires incremental offerings: Level 2 needs 20 Pyroculus, Level 3 needs 22, and max Level 10 needs 40 for the final upgrade.
Unlike respawning resources, Pyroculus don't regenerate after collection, making systematic tracking essential. The 271 total includes 108 in initial 5.0 areas (released August 28, 2025), with updates expanding underground networks.

Natlan's Underground Cave Network
Natlan's subterranean architecture differs through multi-layered vertical cave systems and Phlogiston-dependent traversal. Underground zones like Sulfurous Veins, Saurian Research Facility, Molten Fissure, Colorfall Cave, and Tonatiuh Underground create interconnected pathways requiring specific Saurian abilities.
Key abilities:
- Tepetlisaur: Vertical climbing on designated surfaces
- Yumkasaurus: Horizontal grappling across gaps
- Koholasaur: Rapid vertical ejection in water-filled caverns
Exploration Percentage Calculation
Exploration percentage aggregates waypoint activation, domain discovery, chest collection, and oculi gathering. While Pyroculus significantly contributes, 99% exploration doesn't guarantee all oculi found. Underground areas track separately from surface regions—activating underground teleport waypoints is prerequisite for registering that zone's collectibles.
Prerequisites: Quest-Locked Areas
Several underground Pyroculus remain inaccessible until specific quest completion:
- Begin Adventure Zone Quest: Unlocks Pyroculus 36 and 37
- Tracer No Tracing: Unlocks Pyroculus 101
- Saurian Research Facility sections: Require quest progression for enemy spawns (Pyroculus 53)
Why Finding Last 3 Underground Oculi is Challenging
Common Reasons for 97-99% Stuck
Vertical positioning oversight: Pyroculus 13 floats above a Phlogiston bridge in Sulfurous Veins at unreachable height from ground level. Players walking beneath won't trigger collection without proper vertical positioning.
Repetitive architecture: Saurian Research Facility contains identical corridors, causing players to miss parallel passages with Pyroculus 51, which requires Yumkasaurus activation from specific anchor points.
Phase-Locked Oculi
Certain Pyroculus only spawn after quest phases complete. Pyroculus 36 requires teleporting to underground waypoints and navigating to a waterfall location accessible only post-quest. Tonatiuh Underground contains 5 Pyroculus across quest-dependent zones—early collection is impossible regardless of thoroughness.
Visual Obstruction
Underground environments use darker lighting that obscures Pyroculus glow. Molten Fissure's lava illumination creates visual noise masking positioning. Colorfall Cave's waterfall effects and mist obscure Pyroculus 6 until specific angles achieved.
Multi-Layer Confusion
Natlan's underground zones stack multiple traversable layers at different elevations. Pyroculus 83 requires Tepetlisaurus to enter Molten Fissure at specific elevation, then navigate downward. Players exploring only upper or lower tiers miss intermediate-level collectibles.
Essential Tools and Preparation
Oculi Resonance Stone
Provides directional guidance toward nearest uncollected Pyroculus within detection range. Crafting requires Natlan materials with cooldown mechanics. Deploy at central underground waypoints to maximize coverage before cooldown triggers.
Pro tip: Use after eliminating obvious surface oculi to focus detection on genuinely hidden collectibles.
Best Characters
Stamina efficiency:
- Yelan: Extended sprint, reduced stamina consumption
- Sayu: Alternative stamina-efficient movement
- Kazuha: Mid-air repositioning for elevated positions
- Venti: Updrafts for vertical shafts
- Zhongli: Shield prevents climbing interruption
Elemental Sight
Highlights Pyroculus through environmental obstructions, revealing collectibles behind cave walls. Works best when systematically sweeping camera angles at intersections to detect oculi in adjacent passages.
Stamina Foods
- Northern Smoked Chicken/Satisfying Salad: Immediate stamina recovery
- Sticky Honey Roast: Decreased consumption rates
Consume before long climbing sequences, not mid-climb, to prevent animation interruptions.
Map Pin System
Create color-coded scheme:
- Blue: Confirmed collected
- Red: Inaccessible (needs quest)
- Yellow: Suspicious areas needing re-investigation
Add elevation labels like upper tier checked for multi-level areas.
Systematic Search Strategy
Grid Search Pattern
Divide regions into sectors based on teleport waypoint coverage. Sulfurous Veins: northern passages, central Phlogiston bridge, southern tunnels. Complete each sector before advancing.
Vertical methodology: Search uppermost tier completely, mark locations, descend through intermediate levels, then explore lowest chambers. Prevents missing elevated positions.
Resonance Stone Optimization
Activate only after eliminating obvious oculi. Record directional indication immediately—visual indicator disappears quickly. When stone indicates nearby Pyroculus but visual scan fails, systematically adjust elevation. Many hide directly above/below current position.
Cross-Reference Map Progress
In-game map exploration percentage updates real-time. Compare current percentage against theoretical maximum for completed quest phases. Underground zones display separately at appropriate zoom—identify incomplete zones and concentrate there.
Record Search Path
Maintain text log: checked all passages east of Molten Fissure waypoint or cleared Saurian Research Facility upper level. Screenshot complex spaces showing character position relative to landmarks.
Commonly Missed Underground Pyroculus
Sulfurous Veins: Phlogiston Bridge (Pyroculus 13)
Floats above Phlogiston bridge at elevation requiring specific approach. From nearest waypoint, navigate to bridge. Indwell Tepetlisaur, climb vertical rock face adjacent to eastern support pillar.
At apex, position on narrow ledge overlooking bridge. Pyroculus hovers three character-heights above walkable surface. Time jump from ledge or use Kazuha's skill/Venti's burst.
Saurian Research Facility (Pyroculus 51)
Requires Yumkasaurus grappling. Enter main corridor, proceed to large open room with vertical support beams. Locate yellow grapple point on northwestern beam, halfway up.
Indwell Yumkasaurus, grapple to first anchor. Immediately redirect to second anchor on suspended platform's underside. Pyroculus rests on platform's upper surface—climb after grappling to edge.
Molten Fissure: Tepetlisaurus Puzzle (Pyroculus 84)
Locate switch mechanism on western wall with glowing Phlogiston receptacle. Indwell Tepetlisaurus, maintain Phlogiston reserves above 50%. Activate infusion ability adjacent to switch, triggering hidden passage.
Enter immediately before timer expires. Navigate corridor to chamber with Pyroculus 84 on raised platform. Puzzle resets if you exit.
Colorfall Cave Terminal (Pyroculus 6)
Access through ground entrance southeast of Easybreeze Market waypoint. Descend circular opening, follow linear path toward waterfall sounds.
Final chamber features multi-tiered waterfall. Pyroculus on ledge behind water curtain. Approach from eastern side using rock formations as stepping stones. Waterfall effects obscure until within collection range.
Tonatiuh Underground: Building Platform
Teleport to waypoint, head east to multi-story building. Pyroculus on uppermost platform. Enter ground-level doorway, ascend internal staircase to top floor, exit rooftop access.
Platform extends from eastern face—short climb from rooftop. Alternative: teleport, head west to rear entrance, climb external scaffolding directly.
Underground Facilities: Waterfall (Pyroculus 36)
Requires Begin Adventure Zone Quest completion. Teleport to underground waypoint, navigate to waterfall area. Pyroculus on ledge mid-height along water flow.
Approach from upper entrance, use rock protrusions descending to ledge elevation. Pre-quest attempts result in blocked passages.
Guiztli Path: Wooden Barrier (Pyroculus 37)
Requires Begin Adventure Zone Quest. Teleport to waypoint, head west to wooden barrier across corridor. Deploy claymore or Pyro attacks to destroy planks.
Navigate short corridor to chamber with Pyroculus 37 on central pedestal. Barrier resembles decorative elements—easily overlooked.
Advanced Collection Techniques
Furnaces of Fiery Embers Puzzle
Teleport to waypoint 12 o'clock northeast of central landmark. Locate glowing yellow sigil on rock formation. Interact to transport to challenge area.
Complete timed switch activation and enemy defeat. Success unlocks treasure chamber with Pyroculus.
Koholasaur Ejection (Pyroculus 100)
Locate underwater cavern, indwell Koholasaur. Navigate to position directly beneath Pyroculus hovering above water surface.
Activate ejection while submerged, launching vertically. Time collection input at apex of ejection arc. Manage stamina for multiple attempts.
Tracer No Tracing Quest (Pyroculus 101)
Appears exclusively during quest, requires jet ability. Progress to aerial traversal segment. Pyroculus visible along flight path.
Activate jet, navigate while maintaining altitude and trajectory. Quest time-limit creates pressure—prioritize collection.
Arched Tree Trunk (Pyroculus 107)
Climb trunk's exterior curvature from base. Initiate climbing where trunk begins upward curve. Maintain stamina—trunk length exceeds standard reserves without buffs.
Pyroculus at arch apex, visible only at uppermost section. Ground-level Elemental Sight fails to penetrate trunk thickness.

Troubleshooting
Quest Phase Verification
When Pyroculus fail to appear, verify quest progression. Access quest log, confirm Begin Adventure Zone Quest and other Natlan quests complete. Incomplete prerequisites prevent spawning.
Check game version against collectible introduction date—post-5.0 Pyroculus require corresponding version updates.
Collision Detection
Exit to main menu, reload client to reset interaction states. Persistent issues: clear game cache through launcher settings.
Co-Op Limitations
Pyroculus collection operates exclusively in single-player. Exit multiplayer before attempting collection. Co-op disables collectible interactions to prevent desynchronization.
Customer Support
Contact only after exhausting troubleshooting. Document with screenshots showing character at exact coordinates, quest status, game version. Legitimate issues: disappeared Pyroculus not registering, persistent collision bugs, quest blockers.
Post-Completion Strategies
Monitor Future Additions
Enable notifications for version updates. Review patch notes for new collectible additions. Version 5.0 released 108 Pyroculus—subsequent updates distribute remaining across new zones.
Leverage Completion
Use accumulated resources for character development and team optimization. Primogems, Mora, materials enable immediate investment in new characters.
Prepare for Next Region
Apply lessons: immediate waypoint activation, consistent map pins, quest completion before collectible gathering. Future regions will build on Saurian mechanics—mastering current prepares for complexity escalation.
