Wuthering Waves 3.7 Echo Erase: A Smaller, Playful Change of Pace

Alongside exploration in Xuanfang and the current character banners, Wuthering Waves 3.7 has a gentler diversion: Echo Erase. Kuro lists it as a leisure event centred on tapping Echo Pieces away. It began on October 22 and runs until November 9, 2026 at 03:59 server time.

This is not a newly published announcement; it is an event still running during the second half of the version. Familiar Echoes appearing as pieces on a game board give the world a different scale from the open-world travel and combat around it.

One stage, two difficulties

Kuro’s October 20 global event infographic says stages become available daily. Each has Easy and Hard difficulties, and completing Easy for that stage unlocks its Hard challenge. Rewards come from completing stage goals. The notice does not describe the mode as a purchase, and it does not spell out every stage’s scoring rules.

That structure gives the mini-game a clear progression: Easy introduces the stage, then Hard offers another challenge on the same stage. The announcement does not give enough information to judge how every stage feels or how difficult it is, so the game itself remains the reference.

What the 400 Astrites and deadline mean

The official infographic lists 400 Astrites in total along with materials connected to Resonator, weapon and Echo progression. The Astrites are tied to event goals; the full amount is not automatically awarded just for opening the event. Actual progress and claim requirements appear on the account’s event page. Participation requires Union Level 14.

Echo Erase ends at 03:59 server time on November 9, earlier than Beyond the Waves: Land of Xuanfang on the same infographic, which ends at 03:59 on November 11. The events have separate progress and rewards, so one deadline should not be assumed to apply to the other. Kuro does not give a single local-time conversion for every region in that notice.

A different role for familiar Echoes

What appeals to me is how the event borrows something recognisable without making every interaction a fight. Kuro’s description is brief: tap pieces away and complete stage goals. It makes an interesting counterpart to the already-open Xuanfang exploration event: one looks outward across the map, while the other brings attention to a small board.

In an October 23 player questions thread, one player asked whether the version’s limited events were locked behind story progress. The official infographic explicitly lists Union Level 14 but does not provide a complete list of other story conditions; follow the in-game description if the account shows further requirements. For Rovers wanting a change of pace in the second half, this is another way to spend time outside combat.
