In Wuthering Waves 3.7, the Echo conclusions for T0 characters don't overturn the old logic: the 12-point COST cap stays in place, and 4-3-3-1-1 remains the standard distribution for main DPS. This guide breaks it down into six sections — version overview, COST rules, stat priority, when to re-farm, Tower of Adversity teams, and resource planning. For exact drops and multipliers, refer to in-game data.
Wuthering Waves 3.7 Patch Window and Events
Dates and what opened
Version 3.7 opened on 2026-09-30 with the new region "Dream Hub of Heaven's Net", and the patch ends 2026-11-11 03:59.
How the event calendar lands
The limited combat event "Heavenly Craft Seeks the Lost" runs 2026-10-08 04:00 to 2026-10-26 03:59. The casual event "Echo Erasure" runs 2026-10-22 10:00 to 2026-11-09 03:59, and the "Past Dream Pact" photo collection stays open permanently . The two limited events sit about two weeks apart, which spreads your stamina peak across the patch instead of forcing a first-week sprint.
Wuthering Waves 3.7 Echo System Recap
The 12-cost ceiling and two layouts
Five equipped echoes can total 12 COST points: boss echoes cost 4, elite echoes cost 3, and common echoes cost 1. That produces two layouts. The 44111 pattern uses two boss echoes plus three common echoes for 11 points and leans toward crit or healing. The 43311 pattern uses one boss, two elites, and two commons for 12 points and leans toward elemental damage and energy regen.
Main stats are decided by COST
COST 4 main stats are limited to ATK%, crit rate, crit damage, HP%, DEF%, or healing bonus. COST 3 main stats cover elemental damage, ATK%, HP%, DEF%, and energy regen. COST 1 main stats are only ATK%, DEF%, and HP%. Main DPS runs 43311 because COST 3 can carry two elemental damage rolls while COST 1 handles flat attack.
Wuthering Waves 3.7 Echo Substats
Main DPS priority
Substats go crit rate and crit damage first, then ATK% and whatever damage bonus your kit actually reads, with a few energy regen rolls if your ultimate rotation stalls. Main stats follow your weapon: if the weapon carries crit rate, take crit damage on the echo, and vice versa.
Healer and support priority
Healer COST 3 echoes should all take energy regen, and the weapon should be the four-star Variation if you have it, otherwise any energy regen weapon. Energy regen accelerates ultimate uptime and stops healers from standing on field building concerto energy by auto-attacking, which drags the whole rotation.
Why COST 1 slots are the cheapest fix
COST 1 echoes are the cheapest place to buy stats, because every clear run drops them in bulk and their main stats only roll ATK%, DEF%, or HP%. When your COST 4 and COST 3 pieces are already correct, replacing three COST 1 echoes is often the fastest way to add a few percent of attack without touching the expensive slots.
Wuthering Waves 3.7 Rebuild or Keep Your Old Sets
Accounts with finished substats
If your main DPS already has double crit finished, do not rush to refarm even if the new sets look stronger. The gain from a new set is usually smaller than the gain from raising the new patch character . Echo upgrade substats are fully random, and the time cost of refarming is routinely underestimated.
Half-finished and fresh accounts
Accounts below roughly half completion should switch straight to the 3.7 sets. Fresh accounts should first push data bank level until gold echoes drop reliably, then worry about sets. On skills, stop at level 9 since 9 to 10 costs more materials than it returns, and fill the mid and side minor talents.
Wuthering Waves 3.7 Tower of Adversity Lineups
How to split main and sub DPS teams
The Tower scores by floor, so organise teams around burst windows: your main DPS team eats the best substats while the sub DPS team handles elemental counters and outro chaining .
| Team | Composition | Echoes and weapon | Rotation |
|---|---|---|---|
| Main DPS burst | Patch DPS + energy support + healer | 43311, two elemental rolls on COST 3 | Support buffs, DPS bursts, healer refills energy |
| Sub DPS quick swap | Sub DPS + aero or off-element main + sustain | 44111 with crit focus | Aero applier sets state, sub DPS chains outro, sustain closes |
| Safety net | Standard five-star + generic support + healer | lowest substat requirement | Generic support leads, standard DPS holds field, healer sustains |
Tower versus the other endgame
The Tower of Adversity leans toward single-target burst and speed kills, while the other endgame mode favours sustained area damage. Do not reuse one lineup for both, because the Tower scores timers while the other mode scores survival and coverage.
Wuthering Waves 3.7 Stamina and Upgrade Order
How to spend waveplates
Farm the new region echoes and event stages in week one, then move to skill materials in week two. Because the limited events open on 2026-10-08 and 2026-10-22, the stamina peak naturally splits across the patch.
| Priority | Task | Reason |
|---|---|---|
| 1 | COST 4 and COST 3 echoes for the main DPS | Decides crit and elemental damage |
| 2 | Limited event rewards | Fixed windows that do not return |
| 3 | Skills to level 9 | 9 to 10 is material-heavy |
| 4 | Sub DPS and healer substats | Affects rotation, has substitutes |
Wuthering Waves 3.7 FAQ
Q: Do I need to refarm old echoes for 3.7?
A: Finished double crit sets can stay; refarming returns less than building a new character. Under half completion, switch to the new sets.
Q: 44111 or 43311 for main DPS?
A: 43311 by default, 12 COST total with two elemental damage rolls on COST 3. Only stack 44111 when you need extreme crit or healing.
Q: When should I stop upgrading an echo?
A: Gold echoes cap at level 25 and unlock one substat every 5 levels; open them 5 levels at a time and feed anything that rolls badly into the next echo .
Q: What main stat goes on a healer's COST 3 echo?
A: Energy regen, with an energy regen weapon. It accelerates ultimate energy and keeps the rotation from stalling.
Q: Are the 3.7 sets mandatory for everyone?
A: No. They are a shortcut for unfinished builds. Accounts already at double crit on the old set should spend waveplates on skills, talents, and the new region's exploration rewards instead.
Action Checklist
- Grade your main DPS substats before deciding to refarm 3.7 sets.
- Match main stats to your weapon: weapon crit rate means echo crit damage.
- Open echo substats 5 levels at a time and stop early when they miss.
- Put both limited events on your calendar: 2026-10-08 and 2026-10-22.
- Keep separate lineups for the Tower and the other endgame mode.
- This guide is revised on GameHub whenever a new patch lands.
