What You Need Before Starting
Lightkeepers' Oath requires the specific character Flins, a 5-star Electro Polearm user, as your active character during lantern interactions. The quest teaches Nod-Krai's vertical navigation and underground passage systems.
For efficient progression through Nod-Krai content, the genshin nodkrai exploration recharge service at BitTopup provides secure Genesis Crystal top-ups with competitive pricing and instant delivery.
You'll activate any 4 of 8 total Oath Lanterns—4 on Lempo Isle and 4 on Paha Isle. This flexible requirement lets you choose the most accessible lanterns based on unlocked teleport waypoints.
Rewards and Benefits
Completion grants 21,500 Mora and 4 Adventurer's Experience. The real value lies in unlocking subsequent Flins questline content and mastering Nod-Krai's navigation systems. Quest completion contributes to regional exploration progress, gating reputation rewards and additional world quests in Snezhnaya.
Prerequisites: Unlocking Flins' Quest Chain
Complete To the Lighthouse at Final Night Cemetery on Paha Isle first. Four required steps:
- Travel to Final Night Cemetery and search for fuel north of the island
- Ascend the lighthouse southeast of Final Night Cemetery island
- Refuel the lighthouse and use the telescope to send a distress signal
- Follow Flins to the beach after signal transmission
To the Lighthouse rewards 20,000 Mora, 3 Hero's Wit, and 150 Adventure EXP.
Common Unlock Issues
If Lightkeepers' Oath won't trigger after completing To the Lighthouse, ensure Flins is your active character when approaching Oath Lanterns. Also unlock the Maroon Basin Teleport Waypoint near Final Night Cemetery—it's a central hub for accessing multiple lantern locations efficiently.
Oath Lantern Mechanics
Oath Lanterns require Flins as the active character to activate. When approached with Flins, lanterns emit a distinctive glow and allow simple interaction—no combat or complex puzzles needed.
Lanterns mark key geographical locations while teaching vertical pathways and hidden passages. Several require climbing, gliding, or navigating underground sections, exposing you to Nod-Krai's multi-layered terrain.
Environmental Patterns
Oath Lanterns remain stationary and visible from moderate distances once you're in the correct area. However, Nod-Krai's vertical terrain often obscures lanterns from ground-level perspectives. Use elevated vantage points and vertical camera controls to scan ravines, shorelines, and elevated platforms.
Complete Lantern Route Walkthrough
Eight Oath Lanterns are distributed across Lempo and Paha Isles. Since only 4 activations are required, optimize your route based on unlocked teleport waypoints.
Lempo Isle Lanterns (4 Total)
Lantern 1: West of Clink-Clank Krumkake Craftshop in a ravine between Frostmoon Enclave and Aino's house. Teleport to Clink-Clank Krumkake Craftshop northeast waypoint. Glide down from the craftshop area rather than climbing—terrain features unstable footing.
Lantern 2: South of Starsand Shoal in a hole beneath a stone figure. This presents the first underground navigation challenge. Look for the stone figure landmark, then search for a ground-level entrance near its base. The hole isn't immediately visible—adjust your view downward while circling the stone figure.
Lantern 3: South of Blue Amber Lake on the shore near a tideseal stone. Teleport to Blue Amber Lake north waypoint for direct access. Most straightforward Lempo Isle lantern, positioned in an open shoreline area. The tideseal stone is an unmistakable landmark.
Lantern 4: North of Nothing Passage at a small port north of Lempo Isle. From the Lempo Isle teleport point, climb eastward to this elevated port. Look for rocky outcroppings forming a natural staircase pattern along the eastern cliff face.
Paha Isle Lanterns (4 Total)
Lantern 5: East side of Paha Isle near the artifact dungeon. Convenient marker for players who've unlocked the nearby domain. Proximity to a major landmark makes this one of the easiest Paha Isle lanterns.
Lantern 6: Southwest of Final Night Cemetery on the northwestern shore of Maroon Basin. Given its proximity to the quest hub, this is typically the first Paha Isle lantern players activate. Clear visibility from Maroon Basin Teleport Waypoint.
Lantern 7: North end of Kuuvahki Experimental Design Bureau at the northern port. Fly to the nearby Tidalseal Stone, then navigate to the port area. The northern port features distinctive architectural elements.
Lantern 8: Northwest of Final Night Cemetery on a remote empty island to the north. Requires the most complex navigation—fly as kuuhenka along the Lunar path to reach the isolated island. The kuuhenka transformation is essential; standard gliding stamina is insufficient.

Optimal Route Sequencing
Most efficient route for minimum completion time activates Lanterns 3, 4, 6, and 7:
- Start at Blue Amber Lake north waypoint → Lantern 3
- Climb to Lempo Isle teleport point → Lantern 4
- Teleport to Maroon Basin waypoint → Lantern 6
- Navigate to Kuuvahki northern port → Lantern 7
- Return to Final Night Cemetery to speak with Flins
This route takes approximately 15-20 minutes for experienced players.
Why Players Get Lost: Common Navigation Mistakes
Nod-Krai's vertical terrain creates unique challenges absent in previous regions. The most frequent mistake involves relying solely on the minimap's 2D representation, which fails to convey elevation changes and underground passages.
Misinterpreting Quest Markers
Quest markers in Nod-Krai often appear directly above or below your current position due to overlapping terrain layers. When a marker seems impossibly close yet unreachable, the target is typically on a different elevation level.
Diagnostic approach:
- If the marker pulses but no interaction prompt appears, look for vertical pathways (climbing routes, cave entrances, gliding launch points)
- Check for environmental clues like wooden scaffolding, rope ladders, or worn stone steps
- Rotate camera to maximum upward or downward angles to reveal hidden entrances
Underground Passage Confusion
Lanterns 2 and 8 specifically challenge players with underground or isolated access. The hole beneath the stone figure for Lantern 2 blends into surrounding terrain texture, especially during certain lighting conditions. Circle the entire perimeter at ground level while watching for subtle entrance indicators like darker texture patches or small gaps.
For Lantern 8's remote island, players frequently underestimate required gliding distance. Activate kuuhenka transformation immediately upon launching from Final Night Cemetery's northern cliff edge rather than attempting standard gliding first.
Troubleshooting: When You're Stuck
First, verify Flins is your active character—this oversight accounts for approximately 30% of reported broken lantern issues.
Identifying Position Using Landmarks
Nod-Krai's distinctive landmarks serve as reliable reference points:
- Clink-Clank Krumkake Craftshop: Unique architectural style and NPC presence
- Blue Amber Lake: Region's largest water body with distinctive blue coloration
- Final Night Cemetery: Central Paha Isle location with lighthouse structure
- Kuuvahki Experimental Design Bureau: Large facility with industrial aesthetic
If completely disoriented, open the map and identify the nearest unlocked teleport waypoint. Teleport there, then use landmark-based navigation.
Strategic Teleport Usage
Rather than struggling with complex terrain, strategic teleport usage saves significant time. Maroon Basin Teleport Waypoint near Final Night Cemetery provides central access to Paha Isle lanterns, while Clink-Clank Krumkake Craftshop northeast waypoint serves Lempo Isle. When stuck between lanterns, teleport to the nearest waypoint and restart from a known position.
Expert Navigation Tips
Party Composition
While Flins must be active for lantern interactions, party composition impacts navigation efficiency:
- Include a character with reduced climbing stamina consumption (Venti's passive or Xiao's climbing bonus)
- Bring an Anemo character for resonance stamina consumption reduction during extended gliding
- Consider Geo characters for creating temporary platforms when navigating vertical sections
Switch to Flins only when approaching lantern interaction range to maximize mobility.
Custom Waypoint Marking
After locating each lantern, place a custom pin on your map even after activation. This aids future exploration when searching for nearby chests, Oculi, or quest objectives. Use different pin colors to categorize locations (blue for lanterns, red for challenging navigation points, yellow for resource nodes).
Time-of-Day Considerations
Certain lantern locations, particularly Lantern 2's underground entrance and Lantern 7's northern port, feature better visibility during specific in-game times. The period between 10:00-14:00 in-game time provides optimal lighting for identifying terrain features. Use the Paimon menu to advance time if current lighting obscures critical navigation elements.
Rewards and Quest Chain Integration
Beyond the immediate 21,500 Mora and 4 Adventurer's Experience, the quest unlocks subsequent Flins questline content. The prerequisite To the Lighthouse contributes an additional 20,000 Mora, 3 Hero's Wit, and 150 Adventure EXP. Combined rewards total 41,500 Mora, 3 Hero's Wit, 4 Adventurer's Experience, and 150 Adventure EXP.
Completing Lightkeepers' Oath contributes to Nod-Krai's overall exploration percentage, which gates reputation system rewards including gadget blueprints, furnishing recipes, and region-specific resources.
Follow-Up Quest Unlocks
After completion, Flins becomes available for additional dialogue interactions at Final Night Cemetery. These conversations unlock subsequent world quests exploring Flins' background as a Lightkeeper and the historical significance of the Oath Lantern network.
