Wuthering Waves 3.7 "Mirror-Locked Illusion, Heart Reflects the Dust" launched on 2026-09-30 with three new 5-piece sonata sets, five new echoes including one COST 4, and two new Tacet Fields (source: Wuthering Waves 3.7 update notice, 2026-09-30). This Wuthering Waves tier list-angled piece skips the ranking table and talks allocation: how to split three teams, how to place echoes, and what to farm first. If you only want to know who is strong this patch, the note on Wuthering Waves character rankings at the end explains why the list alone misleads.

Wuthering Waves 3.7 Version Snapshot
Applicable versions: 3.7 "Mirror-Locked Illusion, Heart Reflects the Dust" (launched 2026-09-30)

What 3.7 added
The three new sonata sets split by role: one leans sustained damage, one leans conductive burst, one leans buffing and rotation. There are five new echoes, one of them COST 4, plus two new Tacet Fields as farming spots (source: official 3.7 notice, 2026-09-30). Exact multipliers live in the in-game description; the notice only gives names and counts.
Why the Tower locks teams
The Tower is floor-based and each floor demands a different squad, so characters cannot be reused across floors. That is the whole reason a three-team skeleton beats one god-tier team: you need three squads above the average line, not one at the ceiling.
Wuthering Waves Tower Mechanics: COST 12 and Rotation

Why 12 COST is a budget, not a target
A single character's echo COST caps at 12, and the standard split is 4+3+3+1+1. The 4-cost slot holds the core echo, the two 3-cost slots carry main stats, and the two 1-cost slots complete the set count. This is not "cram the most expensive echoes"; it is "keep the 5-piece bonus alive first, then chase main stats."
A correction worth making: many guides treat the 4-cost echo as the only decision. In practice the 1-cost slots are what complete the set. Drop one and the 5-piece bonus breaks, and that loss usually costs more than a few percent of main-stat value.
Splitting three teams without stealing roles
Split by damage type, not by tier: team one carries the patch DPS into the top floor, team two leans on resonance chains for the middle floor, team three only chases three stars. That way even two four-star cores can still max the star count.
Who gets resonance chains
Chains go to the main DPS first; sub-DPS stops at chain 2. The reason is direct: main DPS chains multiply damage, sub chains mostly buy rotation or buffs with low marginal return.
Wuthering Waves 3.7 Team Compositions

| Team | Shell | Echo split | Purpose |
|---|---|---|---|
| One | Patch DPS + conductive sub + buffer | DPS 4-cost, sub 3+3, support 1+1 | Top floor |
| Two | Permanent DPS + healer + amplifier | DPS 4-cost, rest 3+3+1 | Middle floor |
| Three | 4-star DPS + two supports | DPS 3+3, rest 1+1+1 | Three stars only |
Why team one needs a buffer
Top floors run damage reduction and resistance, so raw DPS panels stall. A buffer's stat amplification is multiplicative and beats adding a second sub-DPS. The trade-off is one fewer damage dealer for roughly 20% amplification; take the amplification.
Why team two needs a healer
Middle floors apply sustained chip damage, and without a healer the rotation breaks inside one wave. The healer only needs 1+1 echoes to complete a set, so it does not compete for 3-cost slots.
Wuthering Waves Echo Farming Budget
What one set costs
Leveling a single echo to max consumes a large amount of tuners and EXP materials, with exact costs shown in the in-game upgrade screen. In practice, a usable 4-cost echo usually takes a dozen-plus Tacet Field runs to roll the right main stat (community farming experience, not an official rate).
| Item | Scale | Note |
|---|---|---|
| Echoes per character | 5 pieces | Total COST 12 or less |
| Set completion | 5 pieces | Breaking the set halves the bonus |
| New Tacet Fields | 2 | 3.7 notice, 2026-09-30 |
| Daily energy | 240 | Per-run cost per in-game value |
Which set to farm first
Farm the main DPS set, then the sub. Farming three sets in parallel leaves all three incomplete and clears zero floors. Ranking content rarely mentions this because it only measures single-target ceilings, not your inventory.
Where do echoes farm fastest?
The new Tacet Fields are the primary 3.7 source, with per-run cost and drop rates per the in-game value; older fields still drop older sets, and if you only need set completion they are more efficient (source: in-game Tacet Field list, checked 2026-11-02). Daily caps are energy-bound: 240 energy is roughly four to six runs.
Are the 3.7 Sets Worth Re-Farming?
Verdict: if you already own a working 5-piece with correct main stats, do not re-farm for the new name; if your set is broken or the main stats are wrong, farm.
- Working 5-piece on the main DPS: skip. The new sets land in the 5% to 10% range, far below the re-farm cost.
- Wrong main stats: farm. Use the new fields to fix main stat and set at the same time.
- New account: build one generic set first. The three-team skeleton matters more than a set name.


Wuthering Waves Tower Combat Tips
Protecting the time score
The Tower scores by clear time, and overtime costs stars. The way to protect it is fewer swaps and fuller combos: swap animations are themselves time, so do not swap just to trigger one reaction.
Which floor to give up
Every rotation has one floor with the worst resistance match. Take three stars there and move on; maxing two floors beats a mediocre run across all three.
Common mistakes
- Three teams fighting over one main DPS, leaving nothing after the lock.
- Sacrificing set count for a 4-cost echo and breaking the 5-piece.
- Pushing a sub-DPS to chain 4 while the main DPS sits at chain 0.

Wuthering Waves 3.7 FAQ
How many characters does the Tower need?
A: Three per team, and since floors lock squads you usually need three teams, so nine characters, with the exact count set by the current rotation's rules.
Does COST 12 have to be 4+3+3+1+1?
A: It is the safest split: 4-cost core echo, two 3-cost main stats, two 1-cost slots to complete the 5-piece bonus.
Which of the three new 3.7 sets fits whom?
A: One leans sustained damage, one leans conductive burst, one leans buffing and rotation (source: official 3.7 notice, 2026-09-30); check the in-game set text for exact fits.
Can I clear the Tower without new echoes?
A: Yes. The Tower rewards rotation and allocation, and older sets with correct main stats still earn three stars.
Action Checklist
- Decide the three-team skeleton before farming any set.
- Give the main DPS the 4-cost core and reserve 1-cost slots for set count.
- Concentrate resonance chains on the main DPS, stop subs at chain 2.
- Farm only the main DPS set in the new fields.
- Take three stars on the worst-resistance floor instead of forcing a full clear.
