Kuro Games shut down Wuthering Waves for Version 3.7, titled “Prism’s Illusion, Heart’s Illumination.” Every region followed the same worldwide timetable, so all servers went offline simultaneously.
Quick answer: Version 3.7 maintenance ran on September 30, 2026 from 4:00 AM to 11:00 AM (UTC+8). Servers reopened early, around 9:30 AM (UTC+8), and Version 3.7 is now live.
Version 3.7 maintenance times by region
The posted window was seven hours long, from 4:00 AM to 11:00 AM (UTC+8). Because the schedule is global, only your local clock changes. Here is when the downtime landed across major time zones.
| Time zone | Maintenance starts | Servers back |
|---|---|---|
| Server (UTC+8) | Sep 30, 4:00 AM | Sep 30, 11:00 AM |
| UTC | Sep 29, 8:00 PM | Sep 30, 3:00 AM |
| PDT (UTC-7) | Sep 29, 1:00 PM | Sep 29, 8:00 PM |
| EDT (UTC-4) | Sep 29, 4:00 PM | Sep 29, 11:00 PM |
| BST/WEST (UTC+1) | Sep 29, 9:00 PM | Sep 30, 4:00 AM |
| CEST (UTC+2) | Sep 29, 10:00 PM | Sep 30, 5:00 AM |
| IST (UTC+5:30) | Sep 30, 1:30 AM | Sep 30, 8:30 AM |
| JST/KST (UTC+9) | Sep 30, 5:00 AM | Sep 30, 12:00 PM |
| AEST (UTC+10) | Sep 30, 6:00 AM | Sep 30, 1:00 PM |
The seven-hour figure is a ceiling, not a promise. Version 3.7 came back roughly 90 minutes early, at about 9:30 AM (UTC+8), which is in line with past patches that opened ahead of the posted end time.
How to confirm the servers are back
Maintenance is finished once the login screen lets you sign in and the client displays Version 3.7 artwork instead of an outage alert. Until service returns, starting the game sends you back to the maintenance notice. Force-quitting the app won’t lift the server lock any sooner.
If rollout issues arise, Kuro may extend maintenance and publish a new notice, often with revised compensation. Server closure at 4:00 AM (UTC+8) cancels anything still in progress, so finish your active session before access is locked.
Maintenance compensation
The downtime reward is 300 Astrite and 2 Crystal Solvent, sent to your in-game mailbox after the servers reopen. You qualify only if you created a character and unlocked Mail before maintenance began at 4:00 AM (UTC+8) on September 30.
Compensation messages expire. Collect yours before maintenance for the next version, and check your inbox for any unclaimed Version 3.6 mail too; that mail also expires with each new version’s server lock.
How to install Version 3.7 on each platform
Preload opened on September 28 at 10:00 AM (UTC+8), so a finished or partial download shortens the update once servers reopen. If you skipped it, the patch downloads the usual way. The method depends on where you play.
| Platform | How to install the update |
|---|---|
| PC | Quit the game, reopen the launcher, and select Update. |
| Android | Start the game and use the update prompt that appears. |
| iOS / Mac | Download the update from the App Store. |
| PS5 | Highlight Wuthering Waves, press OPTIONS, choose Check for Update. |
Steam does not offer preload, so its complete download becomes available only after maintenance finishes. On PC, the launcher may hide “New Version Pre-download” for accounts in the limited resource-tier test; once servers reopen, select a download tier.
What goes live with Version 3.7
Update 3.7 brings two new five-star Electro Resonators: Hsin, a Rectifier featured in As Full as Tonight, Forever Convene, and Suoming, a Sword making her debut in this version. Hsin’s signature weapon, Blooming Jadehaven, has a separate weapon banner, while Suoming’s featured weapon arrives with her. The update unlocks the Simulacrum Nexus of Mengzhou and adds a Main Quest act, new Echoes and Sonata Effects, and events offering Astrite. Before spending on the new banners, log in, claim your compensation mail, and tally your Astrite.
