Wuthering Waves 3.7 Hsin (Heart) Build: Echoes, Weapon and Tower of Adversity Teams

Wuthering Waves 3.7 version overview

Applicable version: 3.7 (launched 2026-09-30, verified against the patch-notes summary)

Wuthering Waves 3.7 went live on 2026-09-30 and closed out the Xuanfang chapter. The first half adds the 5-star Hsin (Heart, Electro Rectifier), the second half adds Suoming (Electro Sword), each with a new 5-star signature weapon, alongside the new region Dreamspire Nexus and a fresh Echo set .

Echoes come first

Hsin's damage sits on Resonance Skill, and the Echo set effect also hangs on applying Electro Flare or triggering Unison, so the set and its stats set her ceiling .

Teammates: Unison versus Electro-Flare

Below 3 chains, run the Unison team; from 6 chains, build around Electro Flare where the ceiling opens up . Pick the lane first, then decide which two slots to fill.

Materials and farming order

The 3.7 region material Listening Blossom needs 60, the skill drops Silk Thread and Hetero Machine Core come from Sunset Dusk, and the weekly boss material Reincarnation Echo needs 26 .

Wuthering Waves 3.7 Hsin's two playstyles

Hsin is a 5-star Electro Rectifier whose core mechanic revolves around Resonance Skill damage, with two modes, Unison and Electro-Flare; the choice decides your Echo main stats and teammates .

Unison mode

In Unison mode Hsin can fire several Variation skills in quick succession, teaming with Unison Resonators to lift the team's damage; it runs on team rotation rhythm .

Electro-Flare mode

In Electro-Flare mode she converts held Electro Burst into Thunderheart Domain and deals Electro Flare damage through Resonance Skill; the ramp is slow, so she needs teammates stacking the debuff .

Low chains go Unison, high chains go Electro

Unison is the low-chain pick because below 3 chains the Electro-Flare ramp is too slow and stable output lags behind Unison.

Wuthering Waves 3.7 Hsin echoes

The dedicated set is the 5-piece Heart of Sworn Vigil: the 2-piece grants Electro DMG bonus, and the 5-piece adds Crit and Electro DMG once her core mechanic triggers, shared by both playstyles .

The 4-3-3-1-1 setup

Run 4-3-3-1-1: Cost 4 takes Crit Rate or Crit DMG, Cost 3 takes Electro DMG bonus, Cost 1 takes ATK%.

COST main stats

For Unison, run double Electro on Cost 3; for Electro-Flare, match your teammate, double Electro with Suisui or double ATK with Buling. Pair Crit Rate and Crit DMG at 1:2 on Cost 4, and watch for Crit overflow with Shorekeeper on the team.

Substats and energy regen

Substat priority is Crit Rate / Crit DMG > ATK% > Resonance Skill DMG > Energy Regen, and Energy Regen depends on the team: 120% for Unison, 125% for Electro-Flare . In testing, a 5% shortfall on regen left the Unison rotation stuck before the second Variation.

Wuthering Waves 3.7 Hsin weapon and materials

Hsin uses a Rectifier, and her damage leans on Crit Rate, Crit DMG and Resonance Skill DMG, so whether a weapon is finished comes down to those three .

Signature: Blooming Jadehaven

Blooming Jadehaven gives 588 ATK and 24.3% Crit Rate, with a passive worth 12% All-Type DMG bonus; on an Electro Flare or Unison trigger, Resonance Skill DMG rises 36% and the target ignores 10% Electro RES .

Budget weapon and materials

The budget pick is Lethean Elegy, about 7.5% to 10% behind the signature, while other 5-star Rectifiers trail by more than 20% . Fully building her also needs about 2,530,000 Shell Credits, 46 Lone Flame of Unity and more . A 7.5% gap saves a signature weapon budget, so unlock teammates first.

Wuthering Waves 3.7 Hsin Tower of Adversity teams

Tower of Adversity is decided by the current floor buffs and team completeness; both Hsin teams work, and both need their own rotation . That is why she shows up twice in Wuthering Waves team comps talk.

Unison burst team

Hsin (Heart of Sworn Vigil) + Suoming (Mirrorflow Thunderflash) + Shorekeeper. Suoming fires her skill and Outro first, then Hsin transforms and deals damage, the two swapping to trigger Variation . Without Shorekeeper, Verina covers her; from 3.8, Lily can take the slot .

Electro-Flare team

Hsin + Electro Rover + Suisui. Rover is free and stacks Electro Flare layers to unlock the 5-piece bonus, while Suisui adds amplification and RES shred . Without Suisui, 4-star Buling works but runs about 21.7% behind .

Floor buffs and positioning

Read the current floor buffs before locking a team; the wrong element wastes characters other floors need . Build in the order character level = weapon level = skill level ahead of Echo substats .

Wuthering Waves 3.7 Hsin skill priority and resonance chains

Which skills you level first decides how smooth the rotation is, and where you stop on Resonance Chains decides whether the spend is worth it .

Skill priority

Max the Inherent Skill first. Unison takes Forte Circuit, Resonance Liberation and Variation to 10 with Normal Attack at 6; Electro-Flare takes Forte Circuit and Liberation to 10, with Normal Attack and Resonance Skill depending on resources .

Resonance chain stopping point

The suggested stop is S0 to S2 to S6. S2 raises several finisher multipliers and cleans up the opener, while S6 adds Resonance Skill DMG and DEF ignore. The middle chains mostly add survivability.

Wuthering Waves 3.7 Hsin FAQ

What deals Hsin's damage?

A：Resonance Skill. Her 5-piece Echo set and signature weapon both hang on Electro Flare and Unison triggers .

How much Energy Regen does Hsin need?

A：120% for Unison, 125% for Electro-Flare; below that the rotation breaks .

Can I skip the signature weapon?

A：Yes. Lethean Elegy is the budget pick, about 7.5% to 10% behind, while other 5-star Rectifiers trail by 20% or more.

Should I run Electro-Flare below 3 chains?
