Sigewinne is the adorable Melusine Head Nurse of the Fortress of Meropide. She is a dedicated Hydro Healer who uses a unique "Bond of Life" mechanic to provide continuous healing and buff the off-field damage of Elemental Skills (like Furina, Fischl, and Yae Miko).

Pros

Strong teamwide healing on Elemental Skill (no Burst needed).
Buffs off-field Elemental Skill DMG for the team.
Excellent synergy with Furina (stacks Fanfare quickly).
Very tanky (Highest Base HP in the game).
Can heal underwater party members (Best for exploration).

Cons

Hydro application is slow and inconsistent.
Buff has a quota (limited hits), making it weak in AoE.
Signature weapon is extremely niche (HP Bow).
Long cooldown on Elemental Skill (18s).

Quick Guide (TL;DR)

If you don't have time for the math, here is the cheat sheet.

Best Artifact: 4pc Ocean-Hued Clam (Healer/DPS) or 4pc Song of Days Past (Buffer).
Alt Artifact: 2pc HP% / 2pc HP% (Stat Stick).
Best Weapon: Silvershower Heartstrings (Signature).
Alt Weapon: Recurve Bow (3⭐ - HP% Stat Stick) or Elegy for the End (Buffing).
Support Weapon: Favonius Warbow (Team Battery - Highly Recommended).
Main Stats: SANDS: HP% | GOBLET: HP% | CIRCLET: HP% or Healing Bonus.
Talent Priority: Elemental Skill > Elemental Burst > Normal Attack.
Top Team: Sigewinne + Furina + Navia/Clorinde + Chiori/Fischl.

Pro Tip: HP Cap: Sigewinne's damage buff maximizes at 65,000 HP. Aim for at least 50k HP to make her buff noticeable. Triple HP artifacts are standard.

Talent Breakdown & Mechanics

Elemental Skill: Rebound Hydrotherapy

Bolstering Bubblebalm: Creates a bubble that bounces between teammates (if C1/C2) or enemies.
Hold E: Charges a larger bubble that traps smaller enemies briefly.
Healing: Heals party members based on Max HP. Also creates "Sourcewater Droplets" for Neuvillette to absorb.
Buff: Grants a flat DMG increase to off-field Elemental Skill damage for the team.

Elemental Burst: Super Saturated Syringing

Cost: 70 Energy | Cooldown: 18s
The Spray: Deals AoE Hydro DMG and applies Hydro.
Usage: Mostly used for applying Hydro or triggering Clam set damage. Healing is tied to Skill, so Burst is secondary for sustain.

Passive: Requires Appropriate Rest

The Buff: Based on the total HP of all party members, Sigewinne grants "Convalescence" stacks.
Effect: Increases the DMG of off-field Elemental Skills (e.g. Furina's Salon Members, Fischl's Oz) by a flat amount. Max 10 stacks per skill use.
Scaling: Buff maxes out at 65,000 HP on Sigewinne.

Talent Priority Order:

Elemental Skill (Level 10) - Primary healing and buff source.
Elemental Burst (Level 8) - Extra damage.
Normal Attack (Level 1) - Ignore.

Stat Requirements & ER Thresholds

Sigewinne is HP hungry. ER is less critical as her healing is on Skill.

Team Context	Weapon	ER Requirement
Double Hydro (w/ Furina)	Recurve Bow	140% - 160%
Solo Hydro	Favonius Warbow	180% - 200%
Healer Only (No Burst)	Any HP Bow	0%

Substat Priority:

HP% (Priority #1 - Aim for 50k+)
Flat HP
Energy Recharge (Comfort)
CRIT Rate (Only for Favonius)

Best Artifacts Comparison

Set Name	Role	Reasoning
4pc Ocean-Hued Clam	BiS Healer	Converts her massive healing into Physical DMG bubbles (30k). Since she overheals a lot, this adds significant team DPS.
4pc Song of Days Past	Buffer	Records healing to buff active character's DMG. Good if you want to buff a hypercarry like Neuvillette further.
2pc HP / 2pc HP	Max HP	Easiest way to reach the 65k HP cap for her passive buff. Recommended if you lack good 4pc sets.

Weapon Rankings

Weapon	Type	Performance	Notes
Silvershower Heartstrings	HP%	S+	Signature. Massive 66% HP stat. The only bow that significantly boosts her HP scaling.
Recurve Bow	HP%	S (3-Star)	The only F2P HP bow. Surprisingly her second best option for maximizing buffs. Do not delete it!
Favonius Warbow	ER%	S (Battery)	Best if your team needs energy (e.g., Furina needs help). Requires Crit Rate on artifacts.
Elegy for the End	ER%	A (Buffing)	Buffs Team EM/ATK. Good for reaction teams, but harder to proc consistently with Sigewinne's slow hits.

Constellation Value

Sigewinne is complete at C0. C1 and C2 improve her buffing capabilities.

C1: The Spirits of the Springs... - (Buff Upgrade) Increases the damage quota of her Skill buff (more hits boosted). Also increases the damage of her bounce. Great QoL.
C2: The Spirit of the Waves... - (Shield) Skill creates a bubble shield that absorbs Hydro DMG. Also reduces Hydro RES of enemies. Good defensive utility.
C6: The Spirit of the Radiant... - (DPS) Massive increase to Burst Crit Rate/DMG based on Max HP. Turns her into a viable Burst Nuke healer.

Verdict: C0 is perfect. C1 makes her buff last longer for fast attackers.

Top Team Compositions

1. Furina Taser/Skill

Main DPS: Clorinde / Yae Miko
Buffer: Furina
Healer/Buffer: Sigewinne
Flex: Fischl / Kazuha

Why it works: Sigewinne heals Furina's drain, maxing Fanfare. Her passive buffs Yae/Fischl/Furina's skill damage. Clorinde drives the reactions.

2. Mono Hydro / Wet Rock

Main DPS: Neuvillette / Ayato
Sub-DPS: Furina
Healer: Sigewinne
Flex: Kazuha / Zhongli

Why it works: Hydro Resonance gives +25% HP (Buffs Neuv, Furina, and Sigewinne). Sigewinne creates droplets for Neuvillette. Very comfy team.

Rotations & Combos

Healer Rotation:
Furina EQ > Sigewinne Hold E (Aim then release) > Sub-DPS > Main DPS

Tip: Hold E to aim and shoot a bigger bubble, but you don't need to hold it for long. Just tap-hold-release to ensure it targets correctly. The bubble bounces automatically.

Frequently Asked Questions

Kokomi vs. Sigewinne?
Kokomi applies Hydro much faster (better for Freeze/Bloom) and can drive teams on-field. Sigewinne provides Skill DMG buffs and heals without needing to stay on-field or manage a circle. Sigewinne is better for Furina/Fischl teams; Kokomi is better for Reaction teams.

Why Recurve Bow?
It is the only free bow with HP% secondary stat. Since Sigewinne's buff scales purely on HP, this 3-star bow outperforms almost every 4-star option.
