NTE Day Off Arc Disk: How to Unlock the Hidden Eclipse Quest

Day Off is a hidden S-Rank Arc Disk in Neverness to Everness (NTE) tied to a six-step encounter chain with an anomaly NPC named Eclipse. There are no quest markers, no journal entries, and no map pings. The chain only progresses when you visit each location with the time set to morning and the weather set to Sunny.

Quick answer: Finish Prologue I and Prologue II, then speak to Eclipse near the ReroRero Phone Booth at the Bureau of Anomaly Control (Area M10). Set the time to 8:00 and weather to Sunny, then meet her on the Film Orbit Studio roof, the Oops Chest Gift Shop rooftop in Illusion Town, the Coastal Highway beach stairs, and the top of Tikal Bridge. Return to the BaC starting spot to claim the Day Off Arc Disk.

Prerequisites for the Day Off Arc Disk

The Eclipse encounter chain stays locked until you have cleared the opening story beats and unlocked free travel around Hethereau. If Eclipse is not standing by the energy ball at BaC Headquarters, the prerequisite has not registered yet, or the in-game time is wrong.

Complete Prologue I (nullify MANISH).
Complete Prologue II (finish the commission and return-home beat).
Have access to the Bureau of Anomaly Control (BaC) in Area M10, far south on the world map.
Be able to open the Time System from the in-game phone menu to set time and weather.

Climbing helps a great deal in steps 2, 3, and 5. Nanally’s wall-running skill, in particular, makes the Tikal Bridge climb significantly faster, but it is not required.

Eclipse encounter walkthrough (six steps)

Each step after the first requires the same condition window: time set to roughly 8:00–10:00 and weather set to Sunny. If Eclipse is missing at the listed spot, reopen the Time System, force the conditions again, and reload the area.

Teleport to the ReroRero Phone Booth at the Bureau of Anomaly Control in Area M10. Turn the camera to your right and approach Eclipse, standing in front of the black energy ball. Speak to her to start the chain. If she is absent, set the time to 08:00 and try again.

Open the phone menu, set weather to Sunny, and advance time to 8:00 the next morning. Travel to Film Orbit Studio on the right side of Hankaku Street and climb to the rooftop. Eclipse will appear here talking about labor and purpose; finish her dialogue.

Reset to 8:00 Sunny again. Head to Illusion Town in the northwest, near Wertheimer Tower, and locate the pink Oops Chest Gift Shop building on Davidia Avenue. Climb to the rooftop. Eclipse will be looking out over a school and speaking about spirals.

Reset to 8:00 Sunny once more. Travel to the beach entrance on the right side of Hankaku Street and follow the Coastal Highway path. Eclipse stands on the street stairs leading down to the beach, contemplating human happiness. No climbing is needed for this stop.

Reset to 8:00 Sunny again. From the Coastal Highway position, look south to spot two red suspension bridges. Go to the northern bridge (Tikal Bridge) and climb the cable in two stages until you reach the highest point. Eclipse appears at the summit, where the Appraiser intervenes in the dialogue.

Return to the Bureau of Anomaly Control and stand in the original spot near the ReroRero Phone Booth and energy ball. Speak to Eclipse one final time. She joins the Appraiser, and the Day Off S-Rank Arc Disk is added to your inventory as the reward.

Why the chain stalls

The encounter only advances when both conditions are correct. Treat each step as a fresh checklist before fast-traveling.

Time outside the 8:00–10:00 morning window will hide Eclipse at the next location.
Any weather other than Sunny will block the spawn, even if the time is correct.
Skipping Step 1 at the BaC means the rest of the chain will not register, even if you stand on the correct rooftops.
You cannot speak to Eclipse again at BaC between Step 1 and Step 6; only the listed map locations advance the chain.

Confirmation that a step worked is simple. Eclipse finishes her line and teleports away on her own. If she does not vanish after dialogue, the step did not register, and the conditions need to be reset before retrying.

Bonus: World Changer achievement with Day Off

Equipping the Day Off Arc unlocks a short follow-up at Unheard Shores in the southwest. Activate the local Wertheimer Tower to clear the fog, then find the Curious Kid standing nearby who talks about wanting to see a solar eclipse.

Set the in-game time to mid-afternoon (around 15:00) so the sun is in the direction the kid is facing, then trigger Day Off’s Eclipse skill (B on keyboard, R on controller). Speak to the kid again while the Eclipse is active to receive the World Changer achievement.

Note: Day Off scales sharply with rank. Even at base rank, the 30% ATK bonus and Ultimate Energy refunds make it a strong fit for Zero or any wearer who leans on Ultimate rotations, so it is worth bringing into the upgrade queue once you reach the Appraisal levels needed to push Arcs past level 60.
