Welkin Moon Enough for Flins? Genshin 7.0 Phase 2 Guide

Direct Answer

Blessing of the Welkin Moon is a value booster, not a Flins ticket. At $4.99 it grants 300 Genesis Crystals on purchase plus 90 primogems per claimed day, totaling 3,000 Primogem-equivalents per 30-day cycle at about $0.00166 per primogem—roughly 9x cheaper than buying crystals at $0.0154 per primogem. Across Flins’ 21-day Phase 2, that daily stream is only ~12 wishes.

Three conditions decide the crystal question: (1) you start on guarantee or already sit in soft pity, (2) leftover primogems from Phase 1 plus version events cover most of the remaining 160-primo wishes, and (3) you stop at C0 instead of chasing C1. Miss any of those and Welkin-only income cannot close a 90-pity or 180-pity hole.

If you already hold a guarantee, 70-plus pity, and a four-digit primo stash, skip extra crystals and claim every Welkin day. If you're off-guarantee with an empty pit, Genshin Genesis Crystals top up Phase 2 Flins after Welkin through buffget only after you count UID, server, leftover primos, and days left—buffget’s competitive pricing, fast delivery, and UID-only checkout keep the top-up limited to the actual gap.

Who can skip Genesis Crystals

Skip crystals when you're on guarantee, already near pull 74–90, and your Welkin logins plus events, Spiral Abyss, and Imaginarium Theater fill the last 10–40 wishes. C0 delivers 80–90% of a character’s kit; Flins reruns have historically returned in months, not years.

Who still needs a crystal top-up

Top up when you lose the 50/50 with low pity, when Phase 1 leftovers are thin, or when you insist on C1 in the same 21-day window. Crystals convert 1:1 to primogems and never expire, but they do not delete 50/50.

Blessing of the Welkin Moon: What You Actually Bank in Phase 2

Welkin costs $4.99 USD (£4.99, €4.99; regional examples include ¥30 CNY, ₩5,900 KRW, ¥610 JPY, ₹499 INR, ₱280 PHP). You receive 300 Genesis Crystals immediately and 90 primogems each day you log in, stacking to 180 days max; buying past that cap refunds 330 Genesis Crystals.

300 crystals plus 90 primogems per claimed day

The 300 crystals are 300 primogems on conversion. Daily 90 primogems over 30 days add 2,700, for 3,000 Primogem-equivalents (18.75 wishes) and about 601 primogems per USD. Welkin is roughly 10% of the price of 3,000 Genesis Crystals for the same primo value.

Converting Welkin income into Intertwined Fates

Genesis Crystals convert to primogems 1:1. One Character Event Wish costs 160 primogems. A 21-day Phase 2 with perfect logins yields 1,890 primogems from dailies alone (~11.8 wishes), plus the 300 upfront only if you buy during that window and have not already counted them.

Missed logins and why they break the plan

Daily rewards reset at 4:00 AM server time (Asia GMT+8, Europe GMT+1, America GMT-5). Each missed day permanently forfeits 90 primogems. Missing 8–10 days in a month drops efficiency to about $0.0024 per primogem and can erase a full 10-pull from a tight Flins plan.

Genesis Crystals vs Welkin Moon: When You Still Buy

Direct packs are 60=$0.99, 300=$4.99, 980=$14.99, 1980=$29.99, 3280=$49.99, 6480=$99.99. First-time double bonuses apply per tier and refresh yearly at anniversary. After Welkin is active, extra crystals are a pity-gap tool, not a better rate.

Conversion math after Welkin is already active

Welkin’s $0.00166 per primogem versus $0.0154 on packs is why you never replace Welkin with crystals. You add crystals only for the wishes Welkin cannot mint inside 21 days. First-time doubles cut that gap; without them, a lost 50/50 is still tens of dollars.

Pack sizes versus a single missed 50/50

A lost 50/50 can demand another 90 pulls (14,400 primogems) to guarantee Flins. That is far beyond 1,890 Welkin primogems. One 1,980 or 3,280 pack after Welkin is a common light-spender patch; it still does not buy a 5-star—only more rolls.

Diminishing returns for Welkin owners

Welkin plus Battle Pass ($9.99, about $0.00756 per primogem) is the best monthly primogem-per-dollar mix and lifts a 42-day version from 107 F2P pulls to 139. Crystals after that stack have the worst rate; use them only for a documented shortfall. If Welkin cannot finish the banner, buy Genesis Crystals Welkin not enough for Flins on buffget with UID and server only—secure transactions, instant delivery, and support that never asks for a password.

Phase 2 Banner Window, Login Days, and Timing Risk

Flins headlines 7.0 Phase 2 “The Lone Light Knocks at Night,” reportedly September 1, 2026 versus September 2, 2026 through September 22, alongside Ineffa’s “Astral Actuation.” Treat the window as 21 days until the in-game timer locks.

How many Welkin days fit a standard Phase 2

Twenty-one claimed days × 90 = 1,890 primogems. Phase 1 (Odette and Arlecchino) runs August 12, 2026 8:00am to September 1, 2026—any unused primos and pity carry into Flins. 7.1 then starts September 23, 2026, so leftover wishes after Flins still have a home.

Starting Welkin mid-banner versus pre-stacking

Buy Welkin before Phase 2 if you can; mid-banner purchases still grant 300 crystals plus remaining daily 90s, but you cannot backfill missed days. Stacking before major character windows or anniversary double-reset is the efficient pattern since Version 1.0.

Aligning reset time with daily claims

Claim after 4:00 AM server, not at your local midnight if they differ. Set a login alarm for the last 48 hours of the banner; those two days are 180 primogems, more than one wish.

Pity Math for Flins: 50/50, Guarantee, and C0 Reality

Character Event Wish base 5-star rate is 0.6% (about 1.6% average). Hard pity is 90; soft pity starts at pull 74; most 5-stars land 76–82. Losing 50/50 guarantees the next featured 5-star. Capturing Radiance (Version 5.0) raises consolidated promotional probability to 55%. Pity carries across limited character banners and is visible in wish history.

Wishes to hard pity versus typical soft-pity range

Worst-case featured 5-star: 180 pulls = 28,800 primogems. Average 5-star: 75–90 pulls (12,000–14,400 primogems). Weapon banner is separate (hard 80, soft 63, Epitomized Path Fate Points) and should not drain a C0 Flins budget.

On-guarantee versus off-guarantee starting points

On-guarantee plus 60 pity means 30 wishes (4,800 primogems) can finish C0 in the typical soft-pity band. Off-guarantee from zero can require two 5-stars. Existing pity is the real swing factor—not Welkin’s 12 Phase 2 pulls.

Why C1 planning changes the crystal question

C1 is another 50/50 after C0. Light spenders ($50–100/month) usually fund one character plus weapon or two C0s, not a same-banner constellation. If C1 is the goal, crystals are expected; if C0 is the goal, they often are not.

Flins is a 5-star Electro Polearm Lunar-Charged DPS (Skill Manifest Flame infusion; Burst Thunderous Symphony). Ineffa is the paired 5-star Electro Polearm support. Signature Bloodsoaked Ruins is optional at C0. Prioritize the character wish, not the weapon banner, unless the roster already has a strong polearm.

Primogems Beyond Welkin During Phase 2 Flins

F2P version income is about 14,540 primogems (107 pulls) per 42 days: Daily Commissions 2,520 (60/day), Spiral Abyss 1,600, Imaginarium Theater 1,000, exploration 1,850, Offering System 950, plus 7 Acquaint Fates. Welkin raises that to 18,320 primogems (131 pulls).

Events, Abyss, and Imaginarium Theater

Phase events, livestream codes (~300 primogems), and maintenance (600–900) sit on top of Abyss and Theater. Lantern Rite-scale patches can add 1,600 primogems plus 10 Intertwined Fates—do not assume that payout in a standard 7.0 Phase 2.

Exploration, quests, and starglitter shop fates

Nod-Krai exploration and quests are the flexible bucket. Paimon’s Bargains can add 10 Intertwined Fates per shop cycle; Masterless Starglitter converts extra 5-stars and 4-stars into more fates. Spend starglitter on Intertwined Fates only if Flins is the locked goal.

Battle Pass as a Welkin companion, not a crystal substitute

Gnostic Hymn at $9.99 is better rate than crystal packs and worse than Welkin. It is a companion pass, not a replacement for a 14,400-primo guarantee hole.

Three Worked Budgets: F2P, Welkin-Only, Welkin Plus Crystals

Assumptions: 160 primogems per wish; Phase 2 = 21 Welkin days if claimed; pity carries; 50/50 unless stated on-guarantee; no weapon banner; C0 stop; event/Abyss/Theater income is version-average, not a festival spike.

Example A — high leftovers, on guarantee. 8,000 leftover primogems, 70 pity, on guarantee, Welkin claimed 21 days (1,890). Effective wishes ≈ 50 leftover + 12 Welkin + events/Abyss/Theater (F2P phases often land 60–80 pulls total). Soft pity is already live; crystals are unnecessary if you do not leak wishes onto Ineffa or the weapon banner.

Example B — empty pit, lost 50/50. 0 pity, off-guarantee, 2,000 leftover primogems, 21 Welkin days. Welkin + leftovers ≈ 24 wishes. A lost 50/50 at pull 80 leaves you far from Flins. Realistic C0 then needs a crystal pack sized to the remaining 90-pull guarantee (up to 14,400 primogems), or you skip and wait for the next Flins window (prior runs: 6.0 Phase 2 Sep 30–Oct 21, 2025; 6.4 Phase 1 Feb 25–Mar 17, 2026).

F2P both-new-5-stars worst case is 57,600 primogems; realistic 43,200. One Welkin cannot fund two limited 5-stars in one version.

Misconceptions That Make Players Overbuy Genesis Crystals

Welkin is not a guaranteed 5-star. Twelve Phase 2 wishes cannot substitute 90 or 180 pity. Buying crystals does not remove 50/50 or raise the 0.6% base rate. Spending cannot “force” Flins; it only buys attempts. Anniversary historically adds about 20 Intertwined Fates—plan around that if the calendar lines up, not around panic packs.

If the roster functions without Lunar-Charged Flins, skipping is smarter than a heavy $300+ constellation chase. C0 is the stopping point for most light spenders.

Decision Checklist: Skip Crystals or Top Up for Phase 2 Flins

Use this gap formula before opening the shop:

1. Count Intertwined Fates + floor(primogems ÷ 160) + Welkin days left × 90 ÷ 160.
2. Subtract from wishes needed: ~16–30 if on-guarantee in soft pity; up to 90 off-guarantee; up to 180 from zero with a lost 50/50.
3. If gap ≤ 0 after events you will actually clear, do not buy crystals.
4. If gap > 0 and Flins is a roster need (not a collection want), size one pack to the gap only.
5. Stop-loss: never send a second payment if delivery is pending; verify UID (nine-digit, bottom-right of the screen) and server; never share password or OTP.

Pull-value filter: need Flins for Lunar-Charged teams → consider a gap pack. Collection-only and 6–12 months to rerun → skip. Level 90 still needs Shivada Jade, 2.7 million Mora, 419 Hero’s Wits, and Thundering Fury—budget Mora and books, not just wishes.

Track the Flins Wish Gap with buffget Before You Spend

Log Welkin remaining days, current pity, 50/50 status, and leftover primogems in one pass. Revisit after Phase 2 events credit extra primos; a late 10-pull from Theater or starglitter can cancel a pack. Buffget covers Welkin and Genesis Crystal packages with competitive pricing, wide game coverage, high user ratings, and customer service that works from an order reference plus masked payment proof if crystals are delayed.

Top-up flow: open the product page, choose Welkin or a crystal pack, enter UID and server, pay once, wait for instant delivery. Escrow-style confirmation means you keep the order reference until the in-game balance updates. Before you buy Genesis Crystals for Phase 2 Flins, log your Welkin days, pity, and primo gap in buffget—see if Blessing of the Welkin Moon already covers the pull, then spend only if the numbers say you must.

FAQ

Is Blessing of the Welkin Moon enough for Phase 2 Flins?
No, not for a guarantee. Welkin adds 1,890 primogems (12 wishes) in 21 days versus up to 28,800 primogems for a guaranteed featured 5-star. It is enough only with leftover pity, on-guarantee status, and event income aimed at C0.

Do you still need to buy Genesis Crystals if you have Welkin Moon?
Only if the wish gap stays positive after Welkin days, leftovers, Abyss, Theater, and events. Crystals are a gap filler, not a Welkin replacement.

How many primogems does Welkin Moon give during a Phase 2 banner?
90 per claimed day. Twenty-one days = 1,890 primogems, plus 300 Genesis Crystals if that purchase lands inside the window and was not already spent.

How many wishes does C0 Flins usually take with 50/50?
Average 5-star is 75–90 wishes; a lost 50/50 can push featured C0 toward 160–180. Soft pity (from pull 74, often 76–82) is where most 5-stars appear.

Does existing pity count toward Phase 2 Flins?
Yes. Limited character pity and guarantee carry over and are the largest swing factor in whether Welkin-only works.

When is it smarter to skip Flins than to buy Genesis Crystals?
Skip when you're off-guarantee with low savings, when C0 is not a team need, or when a rerun in 6–12 months is acceptable. RNG cannot be bought away.
