Wuthering Waves 3.7 "Mirror-Locked Illusion" Guide: Hsin Build, Echo Stats and Tower of Adversity Teams
Wuthering Waves 3.7 Overview: Meng Zhou Nexus and New Echo Sets
Release window and banner order
Version 3.7 runs 42 days, ending November 11, with the second banner phase flipping on October 22. The preview broadcast released three redemption codes: WAKINGMOON, FINDSENTINEL and FALLINGSANCTUM. Redeem them before they expire.
Phase one banners are Hsin, Iuno and Chisa; phase two brings Suoming, Lynae and Roccia's rerun slot. Two new 5-star weapons arrive with the patch: the Rectifier "Jade Gate Mystic Bloom" and the Sword "Sunken Abyss" .
Three new Echo sets
The patch adds the "Dream-Bearing Heart of the World", "Mirror-Shadow Lightning Flash" and "Madder-Remembrance Bloom" Echo sets, tied to the new dream-themed region. The Simulacrum Nexus of Meng Zhou opens alongside them, bringing new enemies including the Patrol Halberd Guard and Jade Abyss Serpent.
On the story side, Chapter IV Act 4 "Meng Zhou: Mind Born of Heart" opens, alongside new Hazard Missions and a Side Story with full voice acting. Log in and complete the check-in on October 22 to claim 10 pulls.
Wuthering Waves 3.7 Hsin Mechanics Breakdown
Electro Rectifier with dual modes
Hsin is a 5-star Electro Rectifier whose defining feature is a dual-mode kit combining "Electromagnetic Effect" and "Unison" (source: official preview coverage; the community often refers to her as the Moon Fox).
Dual-mode Resonators matter for two reasons: the same unit slots into different team tempos depending on mode, and burst windows are easier to align. Before pulling, watch the official preview footage and confirm the mode-swap feel suits your hands - Rectifier pacing is very different from Sword or Broadblade carries.
Should you pull
If your account lacks an Electro on-field carry, Hsin is this patch's environment character and the highest priority. If you simply need a generic damage dealer, compare her against phase two's Suoming, a 5-star Electro Sword, before spending. Same element, two weapon types, two different execution demands.
Wuthering Waves Hsin Echo Build and Cost Allocation
Why 43311 remains standard
Main carry Echo allocation still follows 43311. Cost 4 takes the opposite of your weapon's crit stat - crit damage if your weapon rolls crit rate, crit rate if it rolls crit damage. Cost 3 takes your carry's elemental damage bonus, or one attack and one elemental bonus, which is a negligible difference. Cost 1 takes attack across the board.
The logic is straightforward: let the two high-weight slots handle crit balancing and elemental amplification, and hand flat attack to the cheaper, more common Cost 1 farm. Do not deviate unless a new set's 3-piece bonus clearly points elsewhere.
Main stats and substats
Prioritise crit rate and crit damage in substats, then attack percentage and any damage bonus your carry actually uses. If your ultimate rotation stalls, a few Energy Regen rolls are a fair trade. For healers, build Energy Regen on all three Cost 3 Echo main stats and use the 4-star Variation weapon if available, or any Energy Regen weapon otherwise - Energy Regen accelerates ultimate uptime and stops your healer from standing around auto-attacking while the rotation waits.
On investment order, take skills to level 9 and stop; the material cost from 9 to 10 is steep for the return. Fill the middle and both side columns of the minor talent tree. When enhancing Echoes, do not dump 25 levels at once - open substats five levels at a time and feed a failed Echo into another one.
Wuthering Waves 3.7 Tower of Adversity Team Recommendations
Three team setups
| Team | Configuration | Echoes / weapon | Rotation |
|---|---|---|---|
| Electro dual-core (recommended) | Hsin + Electro support + generic healer | 43311 with weapon and Cost 4 crit stats offsetting | Support buffs first, Hsin enters burst, healer keeps Energy Regen flowing |
| Classic Spectro | Spectro carry + Spectro sub-DPS + sustain | Cost 3 elemental bonus | Sub-DPS applies damage first, carry enters window, sustain cleans up |
| Budget transition | Standard 5-star carry + support healer + shredder | Crit rate/damage on Cost 4 first | Shredder opens, carry plays a full rotation, swap to healer for the loop |
How to split tower floors
Each Tower of Adversity cycle adjusts resistances and buffs, and recent cycles have targeted specific element teams. Do not force one team through every middle tower - place your strongest carry on the floor whose buff it exploits and clear the side towers with your second string.
Wuthering Waves 3.7 Resources and Patch Rewards
Check-in and pull income
Completing the October 22 check-in grants 10 pulls, and the preview codes top up your Astrite further. Take the codes and check-in rewards first, then decide which banner phase to invest in.
Spending Waveplates
With three new Echo sets, Echo domain demand rises sharply. Put roughly 70% of Waveplates into Echo farming and hold 30% for ascension and weapon materials - new-character weeks burn through ascension materials faster than expected.

Wuthering Waves 3.7 FAQ
Q: When does Wuthering Waves 3.7 release?
A: September 30, 2026. The version runs 42 days to November 11, with the second banner phase on October 22.
Q: What are the 3.7 redemption codes?
A: WAKINGMOON, FINDSENTINEL and FALLINGSANCTUM. Redeem them early, as they expire.
Q: Is Hsin worth pulling?
A: She is a 5-star Electro Rectifier with Electromagnetic Effect and Unison dual modes, making her the top priority if your account lacks an Electro on-field carry. Otherwise compare her with phase two's Suoming first.
Q: Should I refarm Echoes immediately for the new sets?
A: No. First confirm the 3-piece bonus fits your carry; 43311 builds remain viable on most Resonators.
Q: Any tips to save resources on Echo enhancement?
A: Do not enhance to 25 in one go. Open substats every 5 levels and feed failures into other Echoes so resources do not get locked into dead rolls.
