Wuthering Waves 3.7 Has More Than Just Hsin and Suoming: What Else Should You Prepare Before September 30?

Wuthering Waves Version 3.7, “Prism's Illusion, Heart's Illumination,” is expected to launch on September 30, 2026. Hsin and Suoming will attract the most attention, but the update is more than two Convenes. It also adds new main and companion quests, Simulacrum Nexus of Mengzhou, five Echoes, three Sonata Effects, permanent exploration content, main story replay, Echo stacking, and camera improvements. Players considering optional purchases can compare kardz and the Wuthering Waves top-up page for Lunites.

Confirmed scope: Version 3.7 is scheduled for September 30. Convene phases and events may use separate start and end times, so always check the in-game event and Convene menus for regional availability.

What Version 3.7 Adds Besides New Resonators

The story continues with Chapter Four Act Four, Simulacrum of the Heart, alongside the companion quest Moonlike Heart, Mortal Longing. Simulacrum Nexus of Mengzhou will open, while Blooms for the Shadow is planned as permanent content. Hsin and Suoming will join the roster with the five-star weapons Blooming Jadehaven and Unspoken Rue.

Five Echoes are being added: Formrender, Soulfrayer, Patrol Squadron, Bloomburst Puppet, and Jade Serpent. Three Sonata Effects will also arrive: Heart of Sworn Vigil, Flash of Electric, and Flower of Tinged Yearning. Phantom: Patrol Squadron will also be obtainable. These additions may change two-piece and five-piece combinations, Main Echo choices, rotations, and inventory management.

Finish Story Prerequisites, but Do Not Rush Permanent Content

Before September 30, check the quest menu for unfinished story requirements leading to Mengzhou. Complete the necessary steps, claim outstanding quest and challenge rewards, and leave enough time to download the update. Skipping dialogue may make it faster to enter the new area, but it removes much of the update’s value.

Because Blooms for the Shadow is permanent, it does not need to consume the entire launch week. Prioritize rewards with deadlines, daily limits, or weekly resets before exploring permanent modes.

Treat Simulacrum Nexus of Mengzhou as an exploration area first. Unlock major teleport points, identify systems that restrict Echo or event access, and mark unfinished branches. Do not spend every exploration item on day one unless a time-limited event requires it.

Story Replay Solves a Different Problem from a Cutscene Archive

Version 3.7 introduces main story replay through the Journey Log. The announced replay range may include To the Shore's End. Replay progress can be saved and continued later or manually reset, with more chapters planned for future updates.

Returning players can rebuild the story context before entering Chapter Four Act Four. Long-term players and creators can revisit important decisions, scenes, and battles without starting another account. Replay the chapters most relevant to Simulacrum of the Heart first.

Do not assume replay grants first-clear rewards again. Unless the live Journey Log clearly lists replay rewards, treat it as a narrative feature rather than an Astrite farming method.

Echo Stacking Saves Space Only Under Specific Conditions

Un equipped and un upgraded Echoes will stack automatically only when their Echo type, Sonata Effect, and Mainstat are identical. Each eligible inventory entry can hold up to 999 copies. Stacking reduces visible inventory rows, but it does not merge substats or change an unwanted Mainstat.

Before the update, lock valuable pieces and check rare Mainstat and Sonata combinations. After the update, inspect several stacks and learn how expansion, sorting, and individual locking work before mass deletion. There is no need to aggressively clear the inventory before launch.

Prepare for the Three New Sonata Effects

Heart of Sworn Vigil, Flash of Electric 覆映吾身, and Flower of Tinged Yearning may expand build options, but their names do not reveal the best use case. Save Echo EXP, Tuners, and Shell Credits until the live descriptions clarify triggers, duration, stacks, and user restrictions.

Keep promising Electro, CRIT, ATK, Energy Regen, and utility combinations. Test the five new Echoes for animation time, swap behavior, interruption risk, and whether their damage or buffs continue after switching. Do not replace a proven setup because of a single critical hit.

Evaluate Hsin, Suoming, and Their Weapons Separately

The two new Resonators and two new five-star weapons do not form a mandatory package. Calculate Astrites, Radiant Tides, Forging Tides, pity progress, and guarantee status separately instead of combining every currency into one optimistic pull count.

Use the trials to check field time, Forte preparation, energy needs, damage type, interruption resistance, Outro value, and team dependence. Do not pull a signature weapon before comparing viable alternatives, passive coverage, and opportunity cost.

Prioritize Events Instead of Farming Everything at Once

The announced Version 3.7 events include Cubie Wars, Gifts of Waking Moon, Echo Erase, Dreams in the Capsule, Past Dreams, Traced Seals, Artisan's Search, and Beyond the Waves: Land of Xuanfang. Waking Moon Fishing and Back to Solaris will appear as web events. Their names do not mean they all open on September 30 or share a deadline, so build a schedule from the live event page.

Sort activities into daily, weekly, one-time story or exploration, and permanent content. Complete daily-limited activities first, then weekly points and shop currencies. Gifts of Singing Drizzle starts on October 22 and will provide ten Radiant Tides in total, so do not count them toward the currency available on launch day.

The Camera Upgrade Is a Practical Account Tool

The camera system adds handheld and selfie modes, pose and expression adjustments, and a more flexible tripod drone view. Clear device storage and organize important screenshots before the update. After launch, test interface hiding, image quality, and camera range.

Seven Steps Before September 30

● Read the update notice and confirm compensation, event windows, and Convene times.

● Claim mail and login rewards, then record your actual currency total.

● Lock valuable Echoes and confirm the stacking rules.

● Open the event calendar and separate daily, weekly, one-time, and permanent content.

● Clear story requirements and enter Simulacrum Nexus.

● Trial Hsin and Suoming with attention to rotations rather than showcase numbers.

● Spend only after checking free income, pity, team needs, and weapon alternatives.

The Best Preparation Is Keeping Your Options Open

Version 3.7 is valuable even beyond its Convenes. Story replay, Echo stacking, Simulacrum Nexus, permanent content, new Sonata Effects, and camera tools can improve every account. Finish prerequisites, save materials, let the new system organize eligible Echoes, and evaluate both characters and weapons after the live details and trials are available.
