Quick Take: Heading into 2025, Ocean-Hued Clam edges out as the top pick for Sigewinne's artifact set. It dishes out 27k AoE Physical DMG from overheals every 3.5s, plus a 15% healing bonus that shines in Spiral Abyss and reaction-heavy teams. Song of Days Past? It pumps 1,200 DMG buffs per stack for single-target hypercarries, but those 6s delays and active-only restrictions hold it back. Aim for 65k HP, 130-150% ER, and go Clam to stay meta-viable—especially with Furina-Navia combos cranking the output. Her rerun hits February 12 to March 4, 2025.
Sigewinne's Spot as Fontaine's Go-To Healer in the 2025 Meta
Getting a Grip on Sigewinne's Healing Tricks and HP Scaling
Sigewinne dropped as a 5-star Hydro Bow user in Version 4.7 Phase 2, back on June 25, 2024. Her heals scale straight off Max HP—think Level 90 stats: 13,348 HP base, 193 ATK, 500 DEF, with a hefty +28.8% HP% from ascension. That Elemental Skill, Rebound Hydrotherapy? It bounces up to five times, patching up the party (skipping herself per bounce, but hitting her at the end) for 2.80-5.95% Max HP plus a flat amount each time. First hit spits out 4 particles, and the Hold version crafts two Bond of Life Droplets at 10% Max HP each—clear 'em for +5 ER per 2,000 HP.
Hit 65k HP, and you're looking at 3k heals per bounce, totaling 15k per Skill cast. Her A4 Passive kicks in too, adding +3% healing for every 1k of party Bond of Life (capping at 30% with 10k Bond). Ascension materials? You'll need Varunada Lazurite from 1-6, 168 Romaritime Flowers, 36 Xenochromatic Crystals, and 46 Water That Failed to Transcend. Level her to 90 with 420,000 Mora; talents run you 4,957,500 Mora plus 3 Crowns of Insight and Philosophies of Equity. (As someone who's farmed enough flowers to last a lifetime, trust me—stock up early.)
Why Picking the Right Artifact Set Can Make or Break Her
Her A1 Passive? It hands out +8% Hydro DMG after a Skill, plus 10 stacks of Convalescence for +80 Skill DMG per 1k HP over 30k—maxing at 2,800 DMG over 18s. At 65k HP, that's perfect fuel for Furina or Yae Miko setups. The Burst, Super Saturated Syringing, unleashes AoE Hydro over 2.5s in six hits (70 energy cost), sucking up 2 Droplets. C6 bumps it with +0.4% CRIT Rate per 1k HP (max 20%) and +2.2% CRIT DMG (max 110%) for 15s.
Talent priority stays Skill > Burst > Normal Attack. Stats-wise, push 60k+ HP and 130-150% ER (or 115-160% in Triple Hydro teams). Oh, and Underwater Emergency Dose auto-heals the active character for 50% Max HP over 2.5s if they're under 50%—20s cooldown—and slaps on -10% All/Physical RES for 10s. Ever wonder why she feels so clutch in clutch moments? It's that seamless blend of sustain and subtle debuffs.
Her Place in the Current Meta: Fitting into Endgame Like a Glove
In 2025's Fontaine Hydro meta, Sigewinne nails 10/10 for healing, 8.5/10 for application, and 10/10 for ease of use. She outshines Baizhu in Furina synergy—C1 wipes out any downtime—and edges Kokomi on off-field buffs. Her rerun lands in Version 5.4 Phase 1 alongside Yumemizuki Mizuki, from February 12 to March 4, 2025, with a solid 9.5/10 Abyss viability.
Downsides? Just one Hydro application every 2s, with an 8s downtime that can cramp Taser or Bloom without Furina or Xingqiu. To slot her in: Farm those Fontaine bosses for ascension first. Build to 65k HP for meta teams next. Then, test her on Abyss Floor 12—expect 9.5/10 clears if you nail it.

Song of Days Past: Deep Dive into This Set for Sigewinne
Breaking Down the 4-Piece Bonus: How It amps Healing Effectiveness
Song of Days Past hit in Version 4.3 on December 20, 2023, from the Waterfall Wen domain. The 2-piece gives a straightforward 15% healing bonus. The 4-piece? It tracks up to 15k HP in healing over 6s through Yearning, then converts it to Waves of Days Past—adding +8% of that recorded amount as DMG to the active character's attacks, Skills, or Burst, stacking up to five times over 10s.
At 65k HP, you max out at +1,200 DMG per hit. Pros: Those CRIT-like buffs pair beautifully with Neuvillette. Cons: It's active-only, needs a 6s wind-up, and the 10-hit cap flops in AoE scenarios. I've tested it enough to say—great for focused bursts, but don't expect miracles in mob swarms.
How It Meshes with Sigewinne's Kit
This set clicks in single-target fights, leveraging her A1 buffs and Skill pulses to rack up those recorded heals for stacks. It aggregates nicely with Yelan or Kokomi in mono-Hydro teams. Picture this: A Skill tap logs 15k heals, turning into +1,200 DMG x5 on Neuvillette's turns.
To pull it off: Fire the Skill before swapping to DPS. Stick around for those 6s to build Yearning. Team it with Kazuha for VV shred. At C1, those extra bounces push stacks to +100 DMG per 1k HP—max 3,500 total. It's like giving your hypercarry a secret weapon, but only if you're patient.
Top Main Stats and Substat Priorities for This Build
Go HP% on Sands, Goblet, and Circlet to hit 60k+ HP. Substats: HP% first, then ER, then CRIT. Farm the East Slopes of Mont Automnequi domain; aim for 130% ER in double Hydro setups. Skip Healing Bonus on the Circlet unless you're all-in on pure sustain—HP% carries more weight here.
Weapons That Shine with Song of Days Past
Her signature, Silvershower Heartstrings, boasts 542 base ATK and 66.2% HP%, plus +40% HP and +28% Burst CRIT Rate at three Remedy stacks from Bonds. F2P option: Recurve Bow at 354 base ATK and 46.9% HP%, restoring 8-16% HP on kills—R5 works wonders with Furina's Fanfare.
Alternative: Elegy for the End with 608 base ATK, 55.1% ER, and +60 EM; four Sigils add +100 EM and +20% party ATK. Steps: Slap on Silvershower and use Droplets for stacks. Refine Recurve for extra HP. If ER's tight, Favonius Warbow (61.3% ER, 60% particle gen on CRIT) saves the day. For the full scoop, check Best Weapons for Sigewinne: Complete Tier List 2025.
Ocean-Hued Clam: Turning Heals into Real Damage
The 4-Piece Mechanics: Crunching Those Bubble Damage Numbers
Ocean-Hued Clam arrived in Version 2.5 on May 31, 2022, from the Slumbering Court domain—craftable at AR45. Two-piece: 15% healing. Four-piece: It builds Sea-Dyed Foam up to 30k HP from heals over 3s, then explodes for 90% of that as Physical DMG every 3.5s. Ignores EM, levels, and reactions entirely.
At 65k HP, those procs hit 27k AoE DMG off-field. Pros: Dead consistent with her Skill pulses. Cons: Physical typing, and the cap bottlenecks if heals stay low. What gets me? It's like your overheals finally pull their weight—pure gold for lazy rotations.
Converting Heals to Damage: Squeezing Every Drop from Clam
This set thrives on turning overheal into DMG, especially without other healers to split the pot. Example: Her 15k Skill heals plus A4 fill the cap quick, netting 27k per rotation. Build to 65k HP without backup healers. Tap the Skill for those pulses. Absorb Droplets in Burst.
It outdamages Emblem at C0, with barely any waste. In my runs, it's the set that turns just a healer into a sneaky DPS contributor.
Teams That Thrive on Ocean-Hued Clam
For Hyperbloom: Sigewinne, Nahida, Raiden/Fischl, Furina—Nahida E Q, then Sigewinne tap E, Raiden E, Fischl Q. Nilou Bloom: Sigewinne, Nilou, Nahida, Yelan—Nilou E N2 E, Sigewinne tap E, Yelan EQ. Furina-Navia: Sigewinne, Furina, Navia, Chiori—Furina ED Q, Sigewinne tap E, Navia Q.
Double Geo for Crystallize, and Hydro Resonance juices ER. Dive into more with Sigewinne Team Compositions for Spiral Abyss.
Fine-Tuning Rotations for Steady Bubble Pops
Keep field time minimal: Tap or Hold Skill for heals, Droplets, and Bond. Burst for 2.5s (jump-cancel it). Swap out—the Foam blows up off-field. Furina Vaporize example: Furina ED Q, Klee E, Kazuha tap EPQ, Sigewinne tap EQ, Klee Q.
Prioritize Skill for A1 uptime; C4 stretches Burst to 5.5s with +8 hits. Details in Sigewinne Talent Priority & Leveling Guide.
Head-to-Head: Song of Days Past vs. Ocean-Hued Clam
Raw Healing Output: The Math and What Tests Show
Both sets kick off with 15% healing from the 2-piece. But Clam flips overheal into 27k AoE DMG every 3.5s, while Song logs over 6s for +1,200 buff x5—but only on the active character. At 65k HP, Clam matches the 15k/Skill heals yet piles on extra output; Song wastes 20-30% in quick-swaps.
From testing: Clam scores 9.5/10 in AoE Abyss floors; Song holds its own in single-target.
Healing Uptime: Clam's instant pulses win. Song's 6s wind-up cuts it by 20-30%.
Consistency: Clam works off-field. Song ties you down, with that 10-hit cap choking AoE.
Damage Breakdown: Real DPS Numbers for Each
Clam drops 27k Physical per proc—80k per rotation in multi-enemy fights. Song? +1,200 x5 equals about 6k buffed DPS on a hypercarry, but over 6s +10s. In Furina teams, Clam adds DMG without burning A1 potential.
2025 data points to Clam leading (27k AoE vs. 1,200 stacks); Song fits Neuvillette with +8% per hit. (My take: Clam's the meta pick unless you're laser-focused on one boss.)
Team Healing vs. Personal Damage: What's the Real Priority?
Clam ramps team AoE and survivability for Abyss runs. Song juices single DPS in hypercarry comps. With Furina, Clam maxes Fanfare through overheal; Song's off-field aggregation falls short. Go Clam for meta clears (9.5/10); Song if single-target sustain's your jam.
Resin Smarts: Farming Efficiency and Domain Access
Clam's Inazuma domain is craftable—low resin burn at AR45. Song's Fontaine spot sees more traffic. Farm 5/5 pieces, chase HP% subs, and track your resin. Simpler path means faster builds.
As you tweak things, low fee Genshin top up via BitTopup delivers cheap, instant credits with ironclad security. It supports tons of games, boasts high satisfaction, and keeps progression hassle-free.
Real-World Tests: How They Stack Up in Spiral Abyss Floor 12
Clear Times Side by Side
On Floor 12, Clam shaves 10-15% off times with 20-30k Foam procs per rotation in AoE—think Furina-Navia: Skill, Burst, swap for 27k explosions. Song drags with its 6s setup, but shines single-target on Neuvillette (+1,200 stacks). Post-4.7 trends? Clam dominates multi-enemy clears.
Survivability Stats: Healing Reliability and Team Longevity
Clam hits 100% uptime via pulses—10/10 healing. Song matches the heals but dips sustain 15% in swaps. C1 Sigewinne with Clam erases downtime; add Furina for Resonance magic.
ER Needs for Smooth Burst Cycling
Base 130-150% ER; drops to 105-140% with Favonius in Triple Hydro. Catch 4 Skill particles. Clear Droplets for +5 ER each. Double Hydro (like Furina) handles 115-160%. ER-starved? Sacrificial Bow resets the Skill.
Prime Teams for Each Set
Song of Days Past: Teams Built for Sustain
Mono-Hydro: Sigewinne, Yelan, Kokomi, Kazuha—Yelan EQ, Sigewinne tap E, Kokomi Q, Kazuha tap EPQ; stacks buff active Hydro. F2P swap: Xingqiu in.
Ocean-Hued Clam: Lineups Geared for Damage
Bloom/Hyperbloom: Sigewinne, Nahida, Raiden, Furina—Nahida E Q, Sigewinne tap E, Raiden E, Furina Q; Clam tacks 27k onto Blooms. Premium: Navia as Geo core.
Hyperbloom and Bloom Synergies: Set Matchups
Clam rules Hyperbloom with AoE procs on Dendro cores. Song buffs Nahida/Raiden Skills. In Nilou Bloom, Clam offsets self-damage with steady heals.
Premium vs. F2P Options Across Builds
Premium: Furina + Neuvillette (Song for buffs). F2P: Fischl + Kazuha (Clam for DMG). More ideas in Sigewinne Team Compositions for Spiral Abyss.
How Constellations Shift Your Set Choice
C0 Sigewinne: Base Performance Winners
At C0, Clam takes it for no-strings DMG. Song's viable but spotty. Rating: Clam as SS-tier support. Straightforward—why complicate when it just works?
C2 and C6 Milestones: Priority Shifts
C1 adds three bounces, juicing A1 to max 3,500—Song stacks love it. C2 brings Bubbly Shield (30% HP, 250% Hydro absorb) and -35% Hydro RES for 8s—teams with Clam for -75% shred via VV. C6? Burst CRIT (20% Rate, 110% DMG) nudges toward Crimson Witch or Aqua Simulacra. Cap at C2 for QoL gains. Full breakdown in Sigewinne Constellation Guide: C0 vs C6.
Advice for Dolphins and F2P Folks
F2P: Stick C0 Clam + Recurve. Dolphins: C2 Clam for that utility edge.
Pitfalls and Pro Tips to Nail It
Stat Mistakes That'll Trip You Up
Under 60k HP? You miss A1's max. Fix: HP% mains upfront, ER second. Ditch Healing Bonus Circlet for HP—it's a trap for most.
Balancing Overheal and Damage: Hit the Sweet Spot
Don't spam Hold Skill on bosses—it's slow, skips the trap. Tap for speed; Hold for mobs and Droplets. At 65k HP, layer CRIT subs after.
Weapons That Mismatch and Hurt
Skipping Bond-synergy weapons wastes passives. Go Recurve or Favonius for F2P ER—reliable picks.
Rotation Blunders That Kill Set Bonuses
Bursting without ER? Downtime city. Skill first, absorb Droplets; lean on double Hydro. Normals? Level to 1 and forget.
Offbeat and Mixed Builds
Mixing 2-Piece Sets: When to Go Hybrid
2pc Clam + 2pc Tenacity: +15% healing, +20% HP, +20% party ATK on Skill. Or 2pc Tenacity + 2pc Vourukasha's Glow for +40% HP total—F2P scaling beast.
Legacy Picks Like Maiden Beloved
Maiden: +15% healing, +20% party DMG post-heal—hybrid option, but trails Clam. Niche: 4pc Fragment of Harmonic Whimsy for Bond focus.
Weird Builds for Niche Challenges
Emblem Burst Hybrid: 4pc Emblem (+20% ER, +25% Burst DMG up to 75% ER) for C6 DPS. Mains: ER Sands, Hydro Goblet, CRIT Circlet. Suits quick-swaps with Yae, Fischl, Nahida.
Building Sigewinne for the Long Haul
Synergies on the Horizon and Meta Guesses
2025's Hydro meta leans Clam hard, especially with Neuvillette's RES shred at C2 and Furina's Fanfare stacks. Against Baizhu, Sigewinne's pure Hydro edge makes her premium.
New Sets Coming: Worth Holding Off?
Clam's evergreen for AoE—stock a R5 Recurve. No need to wait; it adapts to whatever shifts HoYoverse throws.
Strategy for Dedicated Mains
Farm Clam first; grab C2 for utility. With the 5.4 rerun, prioritize Furina synergy. Everything you need in Sigewinne Complete Guide 2025.

FAQ
Which artifact set rules for Sigewinne in 2025?
Ocean-Hued Clam takes the crown for most setups, pumping 27k AoE Physical DMG every 3.5s from 30k HP overheals alongside 15% healing—perfect for Spiral Abyss and Furina-Navia squads. Song of Days Past fits single-target hypercarries with +1,200 DMG buffs from 15k recorded heals, though the 6s delay and active-only vibe hampers quick-swaps.
How do Clam's bubbles play with Sigewinne?
The 4pc builds Foam to 30k HP from heals, popping 90% as Physical DMG every 3.5s off-field. Her Skill pulses (15k at 65k HP) trigger it reliably, layering 27k AoE into Nahida-Raiden Hyperbloom for Abyss wins—no reactions needed.
Best main stats for her healer build?
Sands: HP%; Goblet: HP%; Circlet: HP% (Healing Bonus if sustain's key). It maxes 15k Skill heals and A1 buffs (2,800 DMG at 65k HP). Subs: HP% > ER (130-150%) > CRIT for Convalescence stacks.
HP target for peak healing?
60k+ HP, sweet spot at 65k for full A1 (+80 DMG/1k over 30k, total 2,800) and Clam pops (27k DMG). Delivers 3k per bounce (15k Skill total), boosted by 28.8% ascension HP% and Silvershower's 66.2% HP%.
Does Song boost her healing directly?
The 2pc matches Clam's 15% healing bonus, but 4pc zeros in on +8% of 15k recorded heals (up to 1,200 x5 stacks) for DMG buffs. It pools multi-healer input over 6s via Yearning, giving indirect lifts in Neuvillette-Kazuha teams.
Constellations' impact on sets?
C0 leans Clam for easy DMG. C1 juices Song with extra bounces (+100 DMG/1k, max 3,500). C2 mates Clam with shield and -35% Hydro RES ( -75% total shred with VV); C6 pivots to Emblem for Burst CRIT (20% Rate, 110% DMG). Clam leads C0 meta; C1-C2 for quality-of-life.
