Wuthering Waves 3.7 Opens Simulacrum Nexus and Adds Hsin

Wuthering Waves Version 3.7, "Prism's Illusion, Heart's Illumination," is now available, bringing the next major step in the Mengzhou storyline alongside a new explorable location, playable Resonators, weapons, Echoes, events and a sizeable set of system refinements. The update is being delivered in two phases, with the first available now and the second scheduled to begin on October 22, server time.

For players focused on the ongoing narrative, Version 3.7 advances the main quest through Chapter IV Act IV, "Simulacrum of the Heart." The chapter is paired with the opening of the Simulacrum Nexus of Mengzhou, a new area that expands the setting at the heart of this update. The name of the version itself points to themes of perception and emotion, and the new story material appears set to explore those ideas as the Mengzhou arc moves forward.

The patch is also notable for its combination of immediate content and longer-term additions. Phase I centers on Hsin and a group of returning characters, while Phase II will shift attention to Suoming and another set of returning Resonators. Alongside those banner changes, the update gives players more ways to revisit older main-story material, manage their Echo collections and organize combat teams.

Chapter IV Act IV takes players deeper into Mengzhou

"Simulacrum of the Heart" is the headline story addition in Version 3.7. As Chapter IV Act IV, it serves as the newest installment in the main quest rather than a side activity, making it the clearest destination for Rovers who have been keeping up with the game's story progression.

The opening of the Simulacrum Nexus of Mengzhou gives that chapter a new environment to anchor its events in. New zones in Wuthering Waves typically matter beyond their visual identity, offering another space for exploration and for the encounters, discoveries and collectible-driven routines that accompany a substantial patch. Players should expect the Nexus to be an important part of the version's overall gameplay loop as they work through its story and event content.

A new Tales quest, "Moonlike Heart, Mortal Longing," joins the update as well. Tales quests provide an additional story avenue beyond the core chapter, giving Version 3.7 more narrative material for players who want to spend time with its characters and setting after progressing through the main act.

Another permanent addition is Blooms for the Shadow. Its arrival is important because it is not limited to the active patch window. Permanent events can give both current players and those arriving later a reason to engage with the update's content without the same timing pressure attached to the version's rotating activities.

Phase I introduces Hsin and brings back Chisa and Iuno

Version 3.7 begins with Hsin joining the roster as a new playable Resonator. Hsin arrives during Phase I alongside the returning Chisa and Iuno, giving players a mix of a brand-new character and familiar options in the opening part of the patch.

The featured weapon lineup for Phase I consists of Blooming Jadehaven, Kumokiri and Moongazer's Sigil. As usual for a character-focused update, the new and returning Resonators are accompanied by weapon options that may factor into build decisions for players investing their resources during this phase.

Wuthering Waves' update format frequently asks players to weigh immediate pulls against what is coming next, and the two-part structure of Version 3.7 makes that planning especially relevant. Anyone interested in Hsin, Chisa or Iuno has the opening phase to consider their goals, available currency and existing teams before the featured selection changes later in October.

Beyond banners, Phase I starts the update's broader slate of limited activities. These include Cubie Wars, Dreams in the Capsule, Past Dreams, Traced Seals, Artisan's Search and Echo Erase. There is also Beyond the Waves: Land of Xuanfang, plus the Gifts of Waking Moon login event and Waking Moon Fishing.

Some of these event names suggest a range of formats rather than a single gameplay focus, which should help the patch feel active for explorers, collectors and players who prefer short recurring tasks. Back to Solaris is also included among the update's event offerings, while double-drop opportunities return through Bountiful Crescendo and Chord Cleansing. Those boosted reward periods are particularly useful for players looking to improve characters and equipment efficiently.

Phase II begins October 22 with Suoming, Lucilla and Lynae

The second half of Version 3.7 starts on October 22, based on server time. Phase II introduces Suoming as a playable Resonator and brings Lucilla and Lynae back into the featured lineup.

Its featured weapons are Unspoken Rue, Freeze Frame and Spectrum Blaster. The changeover will give players who are not pursuing the Phase I lineup another set of character and weapon choices, while giving those who are planning ahead a firm point for saving resources.

October 22 also marks the start of the Gifts of Singing Drizzle login event. Players who log in during the event can receive a total of 10 Radiant Tide, along with Premium Tuner and Crystal Solvent. The ten Radiant Tide reward makes the event one of the more immediately practical additions arriving with Phase II, especially for players preparing for featured convenes.

Also listed for purchase from that date is the To the New World - World Tour Concert Pack. The pack includes the Rover's Purrfect Pitch accessory. No further details on its contents were provided beyond that accessory, but its timing connects it to the larger rollout of Version 3.7's second phase.

New Echoes and tools for managing them

Version 3.7 expands the game's Echo selection with several new additions: Formrender, Soulfrayer, Skywatch Lancer, Bloomburst Puppet and Jade Nether Serpent. Echoes remain a fundamental part of character development and combat customization in Wuthering Waves, so each new option has the potential to affect how players approach builds and squad composition.

The update also makes a useful inventory-side improvement through Echo stacking in the Echo Backpack. Echo management can become increasingly cumbersome as a collection grows, particularly for players who regularly farm and sort through potential pieces. Stacking is a straightforward quality-of-life change, but it addresses a routine interaction that can consume considerable time over a long play cycle.

That improvement fits the wider emphasis on player convenience in Version 3.7. Rather than focusing solely on new story and character content, the patch includes practical features intended to make existing systems easier to use and to offer more freedom in how players return to past material.

Story replay, cameras and expanded team organization

One of the most significant permanent system additions is Main Quest Replay through the Journey Log. Players can revisit eligible content from Versions 1.1 and 1.3, as well as the Moon-Chasing Festival from Version 1.2.

For a story-led live-service game, the ability to replay major quest material can be valuable for more than simple nostalgia. It gives returning players a way to refresh their memories before moving ahead, allows lore-focused players to revisit important scenes, and offers an alternative to searching for recaps when they want context for newer chapters. The initial selection is limited to the specified versions and festival content, but it establishes Journey Log replay as a meaningful addition to the game's long-term toolkit.

Version 3.7 also adds Handheld and Selfie camera modes. These options should provide greater flexibility for players using the game's photo features, whether they want to capture scenery in Mengzhou, document characters in their collections or simply take more personalized images while exploring Solaris.

Team management receives a major expansion as well. Players can now maintain up to 20 named, reorderable team setups. The higher limit and naming feature should be especially helpful for accounts with broad rosters, multiple elemental or role-oriented compositions, and separate squads prepared for different activities. Reordering means frequently used lineups can remain easy to find rather than being locked into the sequence in which they were first created.

There is also a limited test of tiered client resource downloads for eligible players. Because the feature is described as a limited test, availability is not universal and players should not assume they will automatically receive it. Still, it signals an effort to explore more flexible download handling for the game client.

A content-heavy update across supported platforms

Version 3.7 is available for Wuthering Waves players on PC, PlayStation 5, Xbox Series X|S, Xbox on PC, Mac, iOS and Android. The update's mix of narrative expansion, character releases, repeatable events and interface improvements makes it a broad package rather than a narrowly focused banner patch.

The newest Pioneer Podcast season is part of that package. It introduces Podcast Tasks and retains the optional Insider and Connoisseur channels for players seeking additional rewards. This gives regular players another progression track to work through while the version's story, exploration and limited-time activities are active.

With Hsin available now, the Simulacrum Nexus open for exploration and "Simulacrum of the Heart" continuing the Mengzhou arc, Version 3.7 has already begun its central rollout. The next major checkpoint arrives October 22, when Suoming joins the roster, Lucilla and Lynae return, the Gifts of Singing Drizzle login campaign starts, and the update moves into its second phase.
