Wuthering Waves 3.7 wrap-up ends at 23:59 on Nov 11 — six days left, counting today. Not much actually expires; there are just four things: Suoming and the two rerun banners, the 10 free login pulls, the doubled Tacet Suppression rewards, and that maintenance compensation sitting in your mailbox. Everything else can wait a few days — these four are gone the moment the clock turns.

Only Four Things Expire in These Six Days
Banners: All Three Close on the Night of the 11th
The second-half limited banner is Suoming, paired with the 5-star sword Chenming, with Linnai and Losera rerunning alongside. Once 23:59 on Nov 11 passes, none of the three can be pulled — the only way in is to wait for 3.8 or later.
One thing to get straight first: no longer being available does not make a character weaker. After the 11th, Suoming is the same Suoming — you simply cannot pull for him anymore. If you are really going to pull, do not leave it to the last day. Past eleven that night, watching the countdown while tapping a 10-pull, your hands shake.
The 10 Login Pulls: One a Day, Miss One and It’s Gone
The login bonus added from Oct 22 comes to 10 Radiant Tides in total. Payouts like this usually arrive day by day: skip a day, lose a pull, with no reminder and no make-up. From today through the 11th, log in and tap once a day. It takes a minute; the hard part is remembering.
Stamina and Mail: Two Easy Things to Forget
Early November doubles the Tacet Suppression rewards. For the next few days, send stamina to the Echo domain first — Echoes are the scarcest thing in this version, and the double drop roughly halves your completion time. How to farm them is covered in part three.
The mailbox is the other one. The 3.7 maintenance compensation is 300 Astrite plus 2 Crystal Solvents, delivered by mail. Mail expires, and accounts that do not log in often are the ones most likely to miss it. Tap it once when you log in this week — 300 Astrite is not much, but throwing it away still stings.
Once those are collected, the only thing left that costs money — and the thing most likely to make you dither — is whether to pull for Suoming.

Should You Pull for Suoming?
With Xin or Without, the Gap Is Real
Suoming's kit is built around Electro synergy. With Xin on the team, Resonance Tune and the electromagnetic effect stack, and the damage rotation actually flows; without Xin he still works, but the damage profile is missing a piece and you have to patch it with substats and the Resonance Chain.
In plain terms, Xin or no Xin means two different damage tiers. So the question is not whether Suoming is strong — it is whether your account can make him strong. A Suoming without Xin is perfectly usable; he just comes up a beat short.
Do Not Let the Phrase “End of Version” Scare You
Every end of version, someone says pulling a new character now is a guaranteed loss. That is not quite right. More precisely, at the end of a version you should do the math on how long a character stays useful. After the 11th, Suoming keeps his full strength — he is not a limited-time Wuthering Waves T0 character; what you pull never expires, only the banner does. For a character who can carry you through 3.8 and 3.9, pricing him as “six days left” is a loss you are inflicting on yourself.
Same logic for the rerun slots. Linnai and Losera are both generalist sub-DPS — exactly what fills the gap when you have your main DPS but the second slot is thin. If both your teams are already built, the reruns mean little; but if you are still propping up a sub-DPS with a 4-star, these few days are your chance to fix the roster. Wait for 3.8 and there is no banner left.
Whether to pull can wait. Pull or not, you are spending this week's stamina anyway, and where you spend it makes a real difference.

On Double-Drop Days, Stamina Goes to Echoes
How to Slot the Five Pieces
Wuthering Waves Echoes come in five slots, and the standard layout is COST4 + 3 + 3 + 1 + 1 — twelve cost points in total. Put the main Echo in the COST4 slot; substat priority goes Crit Rate, Crit DMG, Electro DMG bonus, then ATK%.
Farm the Main Piece First — Do Not Spread Out
During the double-drop days, do not split stamina evenly across five slots; concentrate on the main Echo. Get the main Echo's substats right and the whole set stands up; brick the main Echo and the other four cannot save it. Four secondary Echoes ground out by hand, all feeding one ruined main piece — that is not a finished build.
Assume all daily stamina goes into the Echo domain: substat completion usually takes 2 to 3 weeks (an estimate — official drop rates are not published). Double drops compress it to 1 to 2 weeks, so these days are a bad time to divert stamina anywhere else. Same stamina, half the clock — a good trade.
That covers Echoes. One thing left to work out: whether your Astrite can carry you to 3.8.

How Much Can You Still Bank Before 3.8
Astrite Comes From Dailies; the Bulk Is Events and the Tower
Astrite comes mainly from daily missions, weeklies, Tower of Adversity payouts, and event rewards. Events and the Tower are the one-off bulk; dailies are the steady trickle. For the rest of 3.7, what is guaranteed is dailies, weeklies, plus those 10 login pulls.
You do not farm Astrite deliberately — keep up with dailies and weeklies and it comes. To squeeze out more, hit the one-off sources: at the end of a version, push the Tower to a floor you can clear reliably first, then think about deeper floors.
This Tower Cycle Is Still Doable
The Tower is the thing most often left to the last day. This cycle's Tower of Adversity refreshed on Oct 12; the next one follows the version. Rewards settle by floor, and the safe money is the clear reward — deep floors are gated by the timer more than by floor count, so do not gamble a whole cycle's steady income on one extra floor.
How to split the three routes, by this version's common approach: Havoc team on the left, Glacio team on the right, and Electro synergy (Xin + Suoming) or a Fusion team in the middle. Which route wants which damage type is best read off the stage description before you go in.
3.8 Likely Lands on Nov 12
Extrapolating from 3.7 launching Sept 30 on a 42-day cycle, 3.8 should land around Nov 12 (an estimate, not official — no specific date has been announced). Which means these are the days you have to bank pulls: whatever Astrite you hold after the 11th is what you open 3.8 with. Whether it covers a soft pity — you should have a number in your head by now.
Hold Off on the Weapon Banner
Weapons come last. Priority has always been character over weapon. Chenming adds Electro DMG and synergy gains; without a teammate who can trigger synergy, the signature's value gets cut down hard. Fill out the team first, then talk weapons — same logic at the end of a version. Putting the signature on a Suoming with no synergy partner mostly boosts the stat sheet.

A Final Word
The opening said a batch of things expires six days from now. In practice they do not vanish all at once: the welfare pulls shrink by one a day, the Tower turns the page once rewards are paid, and mail quietly empties at expiry. By the time you notice, it is usually the last day.

Wuthering Waves 3.7 FAQ
When does the second half of 3.7 end?
A: 23:59 on Nov 11 — the Suoming banner, the rerun banners, and the 10 login pulls all close at the same moment.
Is 3.8 Definitely Nov 12?
A: Not officially announced. On a 42-day version cycle it falls on Nov 12 — an estimate.
Can I Still Build Suoming Without Xin?
A: Yes. What is missing is the synergy value, which substats and the Resonance Chain can partly cover — but the damage profile sits one tier below the Xin version.
Is the Echo Double Drop Worth Going All In On?
A: Yes, but concentrate it on the main Echo. It cuts completion time from 2–3 weeks to 1–2.
How Long Before the Compensation Mail Expires?
A: The announcement does not state a fixed number of days; go by the in-game mail timer. Claiming it this week is the safe play.

Action Checklist
- Log in today and clear the mailbox first: claim 300 Astrite and 2 Crystal Solvents.
- Claim one welfare pull a day; all 10 done before 23:59 on Nov 11.
- During the double drop, all stamina to the Echo domain — main Echo first.
- Decide on Suoming before Nov 9; do not leave it to the last day.
- Before Nov 11, push the Tower to a floor you can clear reliably; rewards settle by floor.
The reason to farm the main Echo first is that Echo value is structured as “main piece sets the tone, secondaries fill in the detail” — brick the main piece's substats and every point you put into the other four gets diluted.
