Warren Lucky Flip is a chance-based reward event tied to Neverness to Everness Version 1.2 “999 Nights.” It runs as a limited-time activity during the update rather than as a permanent feature, so the window matters if you want to take part before it closes.
Quick answer: Warren Lucky Flip is scheduled to run from August 5, 05:00 to August 19, 04:59 (server time). It appears in the in-game event menu once that window opens.

Warren Lucky Flip event window
The event is a Version 1.2 activity, which means it becomes available only after the “999 Nights” update goes live and stays open for its fixed run. Because the start date falls later in the patch cycle, it does not overlap with the very first days of Version 1.2.
| Detail | Value |
|---|---|
| Event name | Warren Lucky Flip |
| Version | 1.2 “999 Nights” |
| Start | August 5, 05:00 (Server Time) |
| End | August 19, 04:59 (Server Time) |
Note: All times listed use server time. Your local clock will differ depending on your region, so check the countdown shown on the event banner in-game rather than converting the times yourself.

How to confirm the event is live
Where Warren Lucky Flip sits in the Version 1.2 schedule
Version 1.2 layers several time-limited events across the patch. Warren Lucky Flip is one of the later activities, arriving after the early-patch events wrap up. Lining them up makes it easier to plan which events overlap with the flip window.
| Event | Window (Server Time) |
|---|---|
| Stamina Recharge | July 13, 05:00 – July 20, 04:59 |
| Gold Clash | July 20, 05:00 – August 3, 04:59 |
| Warren Lucky Flip | August 5, 05:00 – August 19, 04:59 |
| Mews Flash | Throughout Version 1.2 |
The update also frames its content around the “999 Nights” mode, a tabletop RPG-inspired game board where you move characters across spaces. That mode and the rotating events run in parallel, so you can work through both while Warren Lucky Flip is open.

Version 1.2 banners running alongside the event
Two limited S-Class banners bracket the flip window. Shinku, a Cosmos damage character paired with her signature Arc Blushing Mirage, headlines Phase 1 from July 8 to July 28. Iroi, an Anima buff character paired with the Arc The Wrong Gate, is expected to run in Phase 2 from July 29 to August 18, which overlaps most of the Warren Lucky Flip period.
If you plan to spend on both banners and events during this stretch, keep in mind that limited character pity carries between limited banners, while Arc banner pity is tracked on its own separate counter. That distinction matters when timing pulls around the same window as the flip event.
The most reliable way to stay on schedule is to treat the in-game countdown as the source of truth. Update to Version 1.2, check the event menu from August 5 server time onward, and clear Warren Lucky Flip before it closes on August 19 so you do not miss the run.
