Welkin Moon Stacking Guide: 180 Days for Mavuika Banner

Welkin Moon Stacking Mechanics

Welkin Moon costs $4.99 USD per 30-day cycle. Each purchase grants 300 Genesis Crystals (converts 1:1 to Primogems) + 90 Primogems daily for 30 days = 3,000 Primogem-equivalents total. Most cost-efficient premium currency option.

Stacking accumulates duration, not simultaneous periods. Multiple purchases add 30 days each to your duration counter. Official max: 180 days (six purchases). Exceeding this triggers 330 Genesis Crystal compensation per excess purchase instead of duration extension—90% value loss.

For gift card conversions, BitTopup offers secure Genshin Crystal Top Up with competitive regional pricing and instant delivery.

180-Day Maximum Explained

Hard cap prevents indefinite accumulation. Six stacked Welkins = $29.94, delivering:

• 1,800 immediate Genesis Crystals (300 × 6)
• 16,200 daily rewards (90 × 180 days)
• Total: 18,000 Primogem-equivalents

Renew when ~150 days remain to avoid compensation threshold. System tracks duration by exact day in your profile under Blessing status.

Duration Accumulation

Simple additive model. First purchase activates 30-day countdown. Subsequent purchases extend timer by 30-day increments. Example: Three Welkins on Dec 1 = continuous rewards through Feb 28 (90 days).

Instant accumulation upon purchase. Check Paimon Menu → Shop → Gift Shop → Recommended. Profile updates immediately, daily rewards claimable at 4AM server time next reset.

Daily Login Requirements

Requires active claims for 90 Primogem reward. Missing login = permanent forfeit, no accumulation or retroactive compensation. Duration decreases one day per 4AM reset regardless of claim status.

Reset time varies by server (America/Europe/Asia/TW-HK-MO). Must log in after reset, before next 24-hour cycle. Set reminders—claim takes seconds, auto-deposits to inventory.

Primogem Accumulation Math

Each Welkin generates 2,700 Primogems from daily rewards (90 × 30) + 300 Genesis Crystals = 3,000 total. That's 601.20 Primogems per USD.

180-day stack: 16,200 daily + 1,800 upfront = 18,000 total ÷ 160 per wish = 112.5 wishes. Excludes free sources (Daily Commissions, events, Spiral Abyss).

Daily Income

Active Welkin adds 90 Primogems daily vs F2P. Combined with Daily Commissions (60) = 150 total daily. Over 30 days: 4,500 Primogems = 28 wishes (including 300 Genesis bonus).

Version 5.3 duration (42 days, Jan 1-Feb 11, 2025): 3,780 from Welkin alone (90 × 42). Add 600 maintenance compensation + ~2,000-2,500 event Primogems = 6,000-7,000 realistic total for active Welkin users.

30-Day Value

$4.99 = 3,000 Primogem-equivalents = 18.75 wishes. Compare to $4.99 Genesis pack (300 crystals = 1.875 wishes). Welkin is 10x more efficient for patient players.

30-day structure aligns with version updates (42 days). Two Welkins at launch = continuous coverage, generating 6,000 Primogem-equivalents (37.5 wishes) for $9.98.

180-Day Stack Total

Six Welkins = $29.94 investment = 18,000 Primogem-equivalents = 112.5 wishes. Guarantees one 5-star (90 hard pity) with 22.5 wishes remaining.

Starting Dec 1 = coverage through May 30, spanning ~4 version updates and 8-10 limited banners.

Primogems to Fates

Intertwined Fates cost 160 Primogems each (Paimon's Bargains). No bulk discounts. Manual conversion required before pulling.

Budget reference:

• 14,400 Primogems = 90 wishes (hard pity)
• 28,800 Primogems = 180 wishes (guaranteed featured after losing 50/50)

Gift Card Conversion

Gift cards → Genesis Crystals → Primogems (1:1) or direct Welkin purchases. Regional pricing varies—same USD yields different Primogem totals by region.

Standard Genesis tiers: $0.99 (60), $4.99 (300), $14.99 (980), $29.99 (1,980), $49.99 (3,280), $99.99 (6,480). First-time purchases double crystals (one-time bonus per tier). Welkin doesn't qualify for first-time bonuses.

Regional Pricing

• US: 601.20 Primogems/USD ($4.99 Welkin)
• Turkey: 784.65 Primogems/USD (₺144.99)
• South Korea: 743.20 Primogems/USD (₩5,900)
• Canada: 632.99 Primogems/USD (CAD $6.79)

Variations from economic adjustments and exchange rates. Account region-locking limits optimization.

Gift Card Calculations

• $25: Five Welkins ($24.95) = 150 days, 15,000 Primogem-equivalents
• $50: Six Welkins ($29.94) + Genesis pack = max stack + immediate pulls
• $100: Six Welkins + $99.99 Genesis (first-time bonus) = 193.5 total wishes

Formula: Gift card value ÷ $4.99, round down = max Welkins. Exceeding 180-day cap = 330 Genesis compensation (inefficient). Use remaining balance for Genesis packs or Battle Pass.

First-Time Bonuses

Double crystals on first purchase per tier (once per account lifetime). $99.99 first-time = 12,960 crystals (81 wishes). Welkin never triggers bonuses.

Strategic: Buy $99.99 pack first (81 wishes) + six Welkins ($29.94, 112.5 wishes over 180 days) = 193.5 total wishes from $130 investment.

Mavuika Banner Costs

Mavuika debuts Jan 1-21, 2025 (Ancient Flame Ablaze banner). Character Event Wish guarantees 5-star within 90 pulls (hard pity), increased rates at pull 74 (soft pity).

Pity operates on cumulative probability. ~90% of 5-stars occur at pulls 74-82 due to soft pity.

Soft Pity (Pull 74)

Requires 11,840 Primogems (74 × 160). Base 0.6% rate increases substantially at this threshold. Statistics show ~35% of 5-stars arrive at exactly pull 74, cumulative 50%+ by pull 77.

Budget 12,000-13,000 Primogems for soft pity window. Max Welkin stack (18,000) comfortably exceeds this, leaving surplus. Combined with Version 5.3 free sources = 24,000-26,000 total for active players.

Hard Pity (Pull 90)

Absolute max: 14,400 Primogems (90 × 160). Guaranteed 5-star regardless of luck. <1% of players reach pull 90 due to soft pity.

Six Welkins (18,000) exceed hard pity by 3,600 Primogems (22.5 wishes) = buffer for 4-star constellations.

50/50 Loss: 180-Pull Budget

First 5-star = 50% featured (Mavuika), 50% standard (Diluc/Mona/Qiqi/Keqing/Jean/Dehya/Tighnari). Losing guarantees next 5-star is featured. Worst case: 180 pulls = 28,800 Primogems.

Exceeds max Welkin value. Need supplemental sources:

• 180-day Welkin: 18,000
• 3 months Daily Commissions: 5,400
• Events: 6,000-7,500
• Abyss: 3,600
• Total: ~28,800+

Constellation Planning

Each constellation = another 5-star pull, same 50/50/pity mechanics. C1 Mavuika (two copies) worst case: 180 pulls (28,800) + 90 pulls (14,400) = 43,200 Primogems.

Max Welkin alone can't fund multiple constellations. Low-spenders: Focus C0 guaranteed, attempt C1 if surplus after early 50/50 wins.

Gift Card Budget Scenarios

$20 Strategy

Four Welkins ($19.96) = 120 days, 12,000 Primogem-equivalents (75 wishes). Dec 1 start = coverage through Mar 31, spanning Mavuika banner + Version 5.4.

Reaches soft pity (11,840) with minimal surplus. Combined free sources over 120 days:

• Daily Commissions: 7,200
• Spiral Abyss (2 resets): 2,400
• Events: 8,000-10,000
• Total: ~30,000 Primogems (guaranteed Mavuika even after losing 50/50)

$50 Optimization

Six Welkins ($29.94) + $14.99 Genesis pack (980, or 1,960 first-time) = 12.25 immediate wishes + 112.5 over 180 days = 124.75 total.

Allocate Genesis for immediate needs (early pity/weapon banner). Reserve Welkin for long-term goals. Balances instant gratification with sustained value.

$100 Maximum

Six Welkins ($29.94) + $99.99 Genesis (12,960 first-time = 81 wishes) = 193.5 total wishes. Guarantees Mavuika (180 worst case) with weapon banner surplus.

Alternative: Six Welkins + $49.99 pack (6,560 first-time = 41 wishes) + $20 for renewals/Battle Pass. Flexible for evolving priorities.

Multiple Gift Cards

Consolidate into max Welkin + Genesis reserves. Two $25 cards ($50) = six Welkins + $14.99 pack. Three $25 cards ($75) = add $49.99 pack.

Plan purchases to exhaust balances completely using natural breakpoints ($4.99/$14.99/$29.99/$49.99/$99.99). Use final $1-3 for $0.99 pack if needed.

Purchase Timing Strategy

Days Until Mavuika

Banner: Jan 1-21, 2025 (21 days). Buying Dec 1 = 31 pre-banner days (2,790 Primogems) + 21 banner days (1,890) = 4,680 Welkin total. Add Daily Commissions (3,120 over 52 days) = 7,800 combined.

From zero Primogems: ~48 wishes including maintenance (600) + events (2,500). For soft pity (74 pulls), start Nov 1 instead = 61 days accumulation (5,490 Welkin + 3,660 Commissions = 9,150).

Avoiding Wasted Days

Mavuika's 21-day window: Welkin bought Jan 1 = only 1,890 Primogems during her availability, rest extends to Version 5.4. Not truly wasted (carries forward), but players targeting only Mavuika should buy 30-60 days early.

Optimal: 90 days before (Oct 3) = 8,100 by Jan 1 + 1,890 during banner = 9,990 total (62 wishes) from Welkin alone.

Version Income Forecast

Per 42-day version (active players):

• Maintenance: 600
• Quests: 500-800
• Events: 1,200-1,800
• Achievements: 200-400
• Abyss: 1,200 (36-star clears)
• Average: 4,000-5,000 free Primogems

Version 5.3 specifics: 600 maintenance + Lantern Rite (1,600+) + Natlan exploration (800) + standard events (1,200) = 4,200 minimum, 5,500+ for completionists. With 42-day Welkin (3,780) = 9,000-10,000 total.

Renewal Tracking

Duration displays in profile under Blessing icon. Set calendar reminders 5-7 days before expiration. Missing renewal = 90 Primogems lost per lapsed day.

Use spreadsheets to track: Welkin expiration, current Primogems, target banner dates, required pulls. Update daily after claims to visualize progress.

Free Primogem Sources

Daily Commissions

60 Primogems for four tasks + Katheryne claim. Independent of Welkin. 30 days = 1,800 (11.25 wishes). 180 days = 10,800 (67.5 wishes).

Combined Welkin + Commissions = 150 daily (90 + 60) = 4,500 per 30 days or 27,000 over 180 days = 168.75 wishes. Sufficient for guaranteed 5-star (180 worst case) with weapon surplus. Takes 10-15 min daily.

Spiral Abyss

Resets 1st and 16th monthly. Up to 600 Primogems per reset (36-star clear). Monthly max: 1,200 (7.5 wishes). Annual: 14,400 (90 wishes) = one hard pity.

Newer players: 200-400 per reset initially. Even 400 consistent (800 monthly) = 9,600 annually (60 wishes).

Events Per Version

1,200-1,800 per version. Major events (Lantern Rite) = 2,000+. Version 5.3: 2,500 minimum, 3,000+ for completionists. Requires 30-60 min daily over 7-14 day periods.

Total Version 5.3 Income (42 days)

• Welkin: 3,780
• Commissions: 2,520
• Abyss (2 resets): 1,200
• Events: 2,500
• Maintenance: 600
• Total: 10,600 (66.25 wishes)

Casual players (400 Abyss, 80% events): ~9,000 (56 wishes)—approaching soft pity from one version.

Common Mistakes

Stacking Beyond 180

Hard cap. Excess purchases = 330 Genesis compensation (2.06 wishes) vs standard 18.75 wishes = 90% value loss. Always check duration before buying. Wait until <150 days to renew.

Buying Too Early

Months before banners risks wasted rewards and disengagement. Optimal: 60-90 days before confirmed dates. For Jan 1 Mavuika, buy Oct-Nov. Avoid Jul-Aug purchases for Jan banners.

Forgetting Claims

Missing login = 90 Primogems lost permanently (0.56 wishes). Missing week = 630 (3.94 wishes) = $1.05 Welkin value. Set consistent times. Mobile claim takes <30 sec.

Welkin Affects Rates

Welkin provides only Primogems/Genesis—doesn't modify probabilities, pity, or rates. 50/50 chances, soft pity (74), hard pity (90) identical for all players. Value = increased wish volume, not quality.

Mavuika Fund Calculator

Current Inventory

1. Check Primogem count
2. Count Intertwined Fates
3. Review pity (Wish → History)

4. Calculate pulls to 5-star (90 - pity)
5. Determine 50/50 status

Example: 5,000 Primogems, 10 Fates, 40 pity, guaranteed featured = need 50 pulls (8,000 Primogems). Current = 41.25 wishes (5,000 ÷ 160 + 10), need 8.75 more (1,400 Primogems).

Welkin Duration Needed

Formula: (Required - Current) ÷ 90 = Days needed

Example: (8,000 - 5,000) ÷ 90 = 33.3 days. One Welkin (30 days) = 2,700, gap covered by 5 days Commissions (300).

From zero for guaranteed (28,800):

• Welkin alone: 320 days (exceeds max)
• Welkin + Commissions: 192 days (150 daily)
• Welkin + Commissions + Events: 120-150 days realistic

Gift Card Allocation

• <30 days: Genesis packs + 1-2 Welkins
• 30-90 days: 2-4 Welkins + mid-tier Genesis
• 90+ days: Six Welkins + remaining for Genesis/renewals

For Jan 1 Mavuika with Dec cards:

• $25: Four Welkins
• $50: Six Welkins + $14.99 Genesis
• $100: Six Welkins + $49.99 Genesis (first-time) + reserve

Timeline Example

• Welkin: 2,790
• Commissions: 1,860
• Events: 1,500
• Subtotal: 6,150 (38.4 wishes)

• Maintenance: 600
• Events: 1,000
• Abyss: 600
• Subtotal: 5,350 (33.4 wishes)

52-day total: 11,500 (71.9 wishes)—reaches soft pity with minimal existing Primogems.

FAQ

How many Welkin Moons stack? Max six (180 days). Excess converts to 330 Genesis compensation—90% value loss vs normal benefits.

Does Welkin expire if you miss claims? Duration decreases daily at 4AM reset regardless of claims. Missing login = permanent forfeit of that day's 90 Primogems. No accumulation or retroactive compensation.

How many primogems from max stack? 18,000 total: 16,200 daily (90 × 180) + 1,800 upfront (300 × 6) = 112.5 wishes.

Is Welkin worth it for Mavuika? Yes. Most cost-efficient at 601.20 Primogems/USD. $4.99 = 18.75 wishes over 30 days—10x better than direct Genesis packs. Active users accumulate 60-70 wishes during Version 5.3.

What if duration exceeds 180 days? Auto-converts to 330 Genesis (2.06 wishes) vs normal 18.75 wishes = 90% loss. Check duration before buying.

Primogems for guaranteed Mavuika? Worst case: 28,800 (180 pulls)—14,400 first hard pity + 14,400 after losing 50/50. Soft pity (pull 74) = realistic 11,840-25,000 range. Budget conservatively for 180 from zero pity.
