Day Off Arc - Eclipse Quest and How to Get MC Signature Arc

Between 6:00 AM and 7:59 PM, fast travel to the ReroRero Phone Booth in the Bureau of Anomaly Control and speak to “Eclipse” in the right corner. The event cannot be progressed by speaking to them between 8:00 PM and 6:00 AM.

First, set the weather to "Sunny" and the time between 6:00 AM and 8:59 AM. Head to the rooftop of the Photo Studio southeast of the ReroRero Phone Booth on Hankaku Street and speak to Eclipse.

When the weather is "Sunny" and the time is between 6:00 AM and 8:59 AM, head to the roof of the brick building southeast of Wertheimer Tower, north of Fiscus Avenue, and speak to Eclipse.

When the weather is "Sunny" and the time is between 6:00 AM and 5:59 PM, head to the roadside along the coast southeast of the ReroRero Phone Booth on Hankaku Street and speak to Eclipse.

When the weather is "Sunny" and the time is between 6:01 AM and 5:59 PM, go to the top of the 1st tower of Tikal Bridge, south of the ReroRero Phone Booth on Hankaku Street, and speak to Eclipse.

Climb from the bottom without using dash or jump. Moving slowly along the wall prevents stamina consumption, allowing you to reach the destination.

By using the gravity-defying effect of Nanally’s skill or the shadow-based movement from Skia, you can climb from the base of the first tower without consuming stamina. However, it’s not possible to reach the top using only skills, so partway up, switch to normal climbing or reuse your Esper Ability from a mid-level foothold.

Between 6:00 AM and 7:59 PM, fast travel to the ReroRero Phone Booth in the Bureau of Anomaly Control and talk to "Eclipse" in the right corner again. After the conversation, you will obtain the "Day Off" Arc.

Use the skill from the equipped “Day Off” Arc to show a solar eclipse to the Curious Kid near Wertheimer Tower in Unheard Shores. Showing him the eclipse will complete the quest, unlock the "World Changer" Achievement, and reward you with Annulith.
