A Wuthering Waves 3.7 guide covering the Xin and Lockming banner split, the three-slot Electro team and its substitutes, echo main and sub stat thresholds, Tower of Adversity rotation priorities, and how much Astrite to hold for 3.8.
Applicable version: 3.7 (3.7.0, launched 2026-09-30)
Wuthering Waves 3.7 at a Glance
3.7 splits two new five-stars across the patch: Xin in the first half and Lockming in the second. Xin is the first playable Sentinel Resonator in the game, holding the Sentinel power Splitting Myriad Forms, which divides her awareness into linked fragments .
Why Xin reshapes the whole Conducto line
Xin is a Conducto element Intoner. Conducto previously had very few playable options, so her banner fills the carry slot and the decision is not just about one unit but about whether your Conducto team exists at all.
Lockming's role and timing
Lockming is a Conducto Broadblade unit and community consensus puts her as the second slot of the Conducto core, with a possible pairing with SP Yangyang in the Havoc line . She arrives in the second half, so there is a gap after Xin to decide whether to follow up.
Wuthering Waves 3.7 Xin Electro Team
The three-slot core
The Electro-effect skeleton is Xin, Rover in Conducto form (two sequences stack ten Electro Concerto layers), and Suisui, whose kit references Electro effects in several places . The upside is a closed loop across three units; the downside is limited room for a fourth.
If you do not have Suisui
Slot Lockming in as the replacement, though her banner opens only in the second half, so in the meantime run Rover. Wuthering Waves tier lists shift a lot between accounts, and the deciding variable is whether you own that effect chain's support.
How to judge a substitute
Judge a substitute by effect uptime rather than sheet damage. Run the same rotation with the substitute and time how long the stacks take to cap; if it lags by three seconds or more, the slot is not a safe stand-in.
Wuthering Waves 3.7 Echo Stats and Thresholds
Check Resonance Efficiency first
Damage is lost whenever the loop drops, so push Resonance Efficiency to the point where a full rotation never stalls before touching damage stats . That threshold depends on your team, so treat the in-game rotation feel as the reference.
Reading the 4-cost main stat
Read crit rate first: below 50% panel crit rate, take crit rate before crit damage or Conducto damage bonus . The reasoning is that crit rate's marginal value is clearly higher while the panel is short of the threshold.
Where to stop on substats
Two of crit rate, crit damage, or ATK are enough; do not chase a full set. The reason is that the same stamina spent on Xin's sequences returns more reliably than rerolling substats.
A Conducto team's damage profile also depends on who applies the effect first. Xin wants the effect already running when her burst lands, so open with the support and only then commit the carry window. Teams that lead with the carry lose roughly one full rotation's worth of effect damage, which is the single most common reason a build looks correct on paper but underperforms in the tower.
Wuthering Waves 3.7 Tower Rotation Priorities
The Tower of Adversity settles by floor and rewards rotation stability across several fights rather than one burst window . Floor counts and the current buff set follow the in-game interface.
Protect the loop before chasing damage
Most wipes happen in the second or third fight: burst carries the first clear, then the loop falls apart. Set the energy and Resonance Efficiency slots first, then add damage.
Tower rewards versus banner budget
Tower rewards are a large slice of patch income but never produce characters. When Astrite is short, clear the tower for its baseline rewards first, then decide whether to hold for the second-half banner.
Wuthering Waves 3.7 Astrite Planning and 3.8
Keep at least one pull tier for the next patch
3.8 and 4.0 still have new characters scheduled, and Xin's alternative Harmony branch is expected to need new teammates . Do not empty your Astrite right after Xin.
Six straight patches of new five-stars
Every patch from SP Yangyang through Lockming has added a new five-star . When resources are short, finish one team rather than leaving two teams each one member short.
Wuthering Waves 3.7 FAQ

A: Xin, Rover in Conducto form, and Suisui; without Suisui you can slot Lockming, but her banner opens in the second half.
How do I pick the echo main stat?
A: Start with crit rate. Below 50% panel crit rate, prioritise crit rate, then crit damage and Conducto damage bonus .

Wuthering Waves 3.7 Action Checklist
- Check whether you own Suisui before deciding between Rover and Lockming in slot two.
- Farm echoes until the rotation never stalls, then add crit rate and crit damage.
- Take crit rate on the 4-cost main stat while panel crit rate is below 50%.
- Climb the tower floor by floor and protect the loop in the later fights.
- Hold one Astrite tier after Xin and wait for the 3.8 teammate schedule.
- Rotation feel and stat thresholds follow the in-game build; this article is revised each patch.
Team and threshold conclusions get revised on gghubs.com as later patches land.
