Wuthering Waves 3.7 Xin & Lockmings Guide

After the transition through Qingxiao and Jingran in Version 3.6, the true finale of the Jinzhou arc is finally here!!! In late August, the official team revealed the character illustrations and profiles of two new characters in succession—“Xin” and “Lockmings.” They will arrive in the first and second halves of Version 3.7 respectively, forming the closing lineup of the Jinzhou chapter.

Let’s start with Lockmings! Her design is immediately recognizable: a red-haired, red-eyed twin-tailed loli whose appearance combines traditional Chinese ink-wash aesthetics with intricate mechanical styling. Metallic locks and ink-dyed patterns create a striking contrast. In the story, she comes from Huating in Jinzhou. To solve her hometown’s “Evil Miasma” crisis, she founded the “Ten Forbidden Lock Contracts.” Later, under the order of the Sentinel, she became the prefectural inspector and took charge of the Truth-Seeking Mirror to protect Jinzhou. Based on the official description that she can “borrow and use their abilities,” she appears to possess a special power that can place other people’s frequencies inside locks, allowing her to control up to ten abilities at once. In terms of element and weapon, Lockmings is an Electro Sword character. She is speculated to be an Annihilation support/sub-DPS, as well as SP Yangyang’s dedicated support, enabling a complete Annihilation team with Yangyang.

If Lockmings is a “system upgrade,” then Xin is undoubtedly the absolute centerpiece of Version 3.7!

As the Sentinel of the Jinzhou region, Xin is the first playable Sentinel Resonator in the Wuthering Waves series and the featured headliner of the Version 3.7 first-half banner. Her white hair, fox ears, and red-and-black color scheme have sparked extensive discussion in the community. The unusual barefoot high-heel design has even been jokingly called a “cosplayer’s nightmare” by overseas players. The banners from Versions 3.5 to 3.7 have already strained many players’ Astrite reserves—SP Yangyang, Suisui, Qingxiao, Jingran, Xin, and Lockmings, with no breathing room across six consecutive character banners. Understanding Xin’s role and team-building direction in advance is far more practical than scrambling after pulling her. This guide organizes all currently confirmed and speculated information in one place.

Release Time and Basic Role

After cross-checking information from multiple sources, Xin’s banner has been confirmed for the first half of Version 3.7, with Lockmings taking over in the second half.

There are currently two schools of thought regarding Xin’s exact role. The mainstream view is that, as a Sentinel Resonator, she is more likely to be a main DPS, following the power trajectory of previous character Cartethyia. However, early leaks suggested that Xin Yuehu might lean toward a “universal support” role, based on the belief that support characters retain their value longer. At present, the main-DPS theory appears more likely, but her final role will have to be verified after she is implemented on the test server.

Confirmed Element and Weapon

Xin has been confirmed as an Electro Rectifier character. There are currently limited options for Electro teams, so her arrival will fill an important gap. According to leaks, Xin’s core team may revolve around the Electro-Magnetic Reaction: Xin + Electro Rover + Suisui, forming a complete Electro-Magnetic Reaction composition.

Recommended weapon direction: Rectifier characters generally rely on the passive activation mechanics of their weapons. If Xin is positioned as an Electro main DPS in Version 3.7, her signature weapon will most likely be designed around “Electro-Magnetic Reaction trigger frequency” or “increased Electro DMG.” As an Electro Sword character, Lockmings may become an upgraded alternative to Electro Rover and further strengthen the Electro-Magnetic Reaction team.

Core Mechanics: “Myriad Forms” and Dual Modes

Ability Profile

According to her official profile, Xin possesses the powerful authority of the Sentinel Xin Yuehu—Myriad Forms, a unique ability that can turn one into many and evolve forms into images. It can split and extend physical objects in her hands, as well as her own consciousness, perception, and information, according to their original form. The resulting manifestations each have an independent shape, yet remain closely connected to the original. They can share perception with one another and merge back into the source whenever necessary.

According to the story background, Xin Yuehu’s true body is actually the central hub of Xuanfang City. From the day the Xuanfang City project was established, she distributed her consciousness, perception, and abilities throughout the city’s Su Mirror network, sacrificing her personal freedom in exchange for the city’s peace. This setting—“beneath a languid and alluring exterior, she would rather sacrifice herself than involve others”—has led many players to sigh that “Sentinel-related stories always come with emotional damage.” In terms of character depth, Xin Yuehu’s story may be the most emotionally intense section of the Jinzhou arc.

Many players have been drawn to this concept and are eagerly awaiting the practical performance of the “clone mechanic” in combat.

Dual-Mode Mechanics Predictions

According to multiple leaks, Xin’s combat system will revolve around two modes:

Electro-Magnetic Reaction Mode: The predicted core lineup is Xin + Electro Rover + Suisui, forming a complete Electro-Magnetic Reaction team. This also ties in with Lockmings’ release arrangement—Electro Rover is the accessible lower-tier alternative, while Lockmings is the final system upgrade.

New Coordinated-Echo System: Xin may later work with new teammates from Version 3.8 and beyond to form an entirely new composition. Leaks indicate that this new system differs from the existing Gathering Echo and Shocking Echo systems. Through this mode, Xin can grant herself buffs, while the new teammates are expected to arrive in Versions 3.8 and 4.0.

Team Predictions and Teammate Analysis

Electro-Magnetic Reaction Team

Core lineup: Xin (Electro·Rectifier) + Electro Rover (Electro·Rover) / Lockmings (Electro·Sword) + Suisui (Support)

Analysis:

▲ Electro Rover: As the accessible lower-tier alternative, Electro Rover can stack 10 layers of Electro-Magnetic Concerto at Sequence 2 and also provides some team buffs, making the character a sub-DPS template. Some players point out that Electro Rover can almost only function as Xin’s second slot teammate.

▲ Lockmings: Arriving in the second-half banner, she is speculated to be an upgraded alternative to Electro Rover or Xin’s second reaction teammate. Lockmings is also believed to work with SP Yangyang and fit the Void-Annihilation composition.

▲ Suisui: The core support of the reaction system. Multiple parts of her skill description are related to Electro reactions, making her almost indispensable in Electro-Magnetic Reaction Mode.

▲ New Coordinated-Echo System: New teammates are expected in Versions 3.8 and 4.0 to complete Xin’s new system. At that point, Xin may have an entirely different team-building direction.

Xin Yuehu’s first-half banner in Version 3.7 is almost here. As the Sentinel of Jinzhou and the first playable Sentinel character, her strength and long-term value are highly anticipated. However, the consecutive banners from Versions 3.5 to 3.7—SP Yangyang, Suisui, Qingxiao, Jingran, Xin Yuehu, and Lockmings—have already put many players’ Astrite reserves under serious pressure. Since Xin Yuehu and Lockmings appear in different banner halves, the resource burden is especially significant for players who want to build a complete Electro-Magnetic Reaction team.
