Sigewinne Build Guide 2026: Mastering Fontaine's Melusine Medic

So, you've pulled the head nurse of the Fortress of Meropide, and now you're wondering how to build her? Is she just another healer, or does this Melusine pack a surprising punch? Let's dive into the optimal way to build Sigewinne, the 5-star Hydro archer who joined the roster back in version 4.7 alongside Clorinde and Sethos. True to her day job, she excels at keeping the party in tip-top shape, but don't let the nurse's uniform fool you—she brings a unique kit to the table. Her abilities scale primarily off her HP, making stat-building a relative breeze. She cleverly utilizes the Bond of Life mechanic to enhance her healing and fuel her Energy needs, and she can even toss out Sourcewater Droplets, which are as handy for her as they are for a certain Chief Justice. Perhaps most intriguingly, she provides a buff to off-field Elemental Skill damage, making her a sneaky-good partner for certain sub-DPS characters. Who knew a nurse could be so versatile?

Best Weapons For Sigewinne: Bows That Boost the Bulk

The first order of business is arming our medic. What's the best tool for the job?

• The Undisputed Champion: Silvershower Heartstrings 🏆

  This is her signature 5-star weapon, and it's practically made for her (because, well, it was). It offers a massive HP sub-stat (66.15% at Lv. 90) and a skill called Remedy. By using her Skill, gaining Bond of Life, or healing (which she can do off-field), she gains Remedy stacks. At 3 stacks, she gets a whopping 40% Max HP increase and a 28% Elemental Burst CRIT Rate bonus. It's the perfect bow that synergizes with her entire playstyle.

• The Premium Alternative: Aqua Simulacra

  Don't have her signature? Yelan's bow is a solid offensive option that still offers a 16% HP bonus from its skill. It's more damage-focused, but that HP bump is nothing to sneeze at.

• The Shockingly Good Budget Pick: Recurve Bow 😲

  Yes, you read that right—a 3-star bow! While its other stats are... forgettable, its HP sub-stat (46.9% at Lv. 90) is incredibly valuable for a pure healer build. In fact, for a dedicated healer, the humble Recurve Bow can outperform Aqua Simulacra! It's the Zhongli-Black-Tassel equivalent for Sigewinne.

• The Energy Recharge Options

  If HP bows are out of reach, look for Energy Recharge. The 4-star Sacrificial Bow is top-tier here because its skill has a chance to reset her Elemental Skill cooldown—the very skill that does the healing! The Favonius Warbow is a close second for team energy generation.

Here’s a quick comparison table for her weapon options:

Weapon	Rarity	Key Stat / Effect	Best For
Silvershower Heartstrings	5★	HP%, Remedy Stacks (HP & Burst CRIT)	Signature Best-in-Slot
Aqua Simulacra	5★	HP% from skill, High CRIT DMG	Hybrid Damage/Heal
Recurve Bow	3★	High HP% sub-stat	Pure, Budget Healer Build
Sacrificial Bow	4★	Energy Recharge, Skill Reset	Healing Uptime & Energy
Favonius Warbow	4★	Energy Recharge, Team Energy	Team Support & Energy

Best Artifacts & Stats: Dressing the Doctor

Now, for her outfit—the Artifacts. As of 2026, two main sets vie for her attention, each with a distinct philosophy.

• The Support Specialist: Song of Days Past 🩺

  This is arguably the best Artifact set for Sigewinne's healer and support build. The 2-piece gives a 15% Healing Bonus, and the 4-piece converts registered healing into a damage bonus for the active character. It perfectly complements her natural role as a buffer who amplifies her team's damage.

• The Off-Field Damage Option: Ocean-Hued Clam 💥

  Want your nurse to deal some damage? This set also provides a 15% Healing Bonus from its 2-piece, but its 4-piece effect creates a bubble that explodes for damage based on healing done. It makes Sigewinne a more active off-field damage contributor. However, her best offensive potential is locked behind Constellations, so focusing on support is often the more effective route.

Stat Priority:

When farming those perfect pieces, remember this order:

1. HP% (Sands, Goblet, Circlet): Prioritize boosting her HP as much as you can. It governs her healing and Burst damage.

2. Healing Bonus (Circlet): A must-have for maximizing her primary role.

3. Energy Recharge: Ensures her Burst is ready when needed.

4. CRIT Rate / CRIT DMG: Since her damage scales from HP, CRIT stats are the best way to amplify it if you want some extra punch.

Best Team Comps: The Ideal Patient Roster

Sigewinne is a very flexible healer. While she plays well with Bond of Life characters like Clorinde, she's not chained to them. The key to her team synergy is her buff to off-field Elemental Skill DMG. Remember, this buffs skills like Fischl's Oz or Raiden Shogun's Eye, but not off-field Burst damage from characters like Yelan or Xingqiu.

• The Dream Team Core: Sigewinne + Furina 💧💧

  She is at her best alongside Furina for two brilliant reasons. First, she buffs Furina's incredibly powerful off-field Skill damage. Second, together they activate Hydro Resonance, boosting the entire team's Max HP, which in turn makes Sigewinne's healing even more potent. It's a match made in Fontaine.

Here are some potent team compositions to consider:

Team Role	Example Composition	How It Works
Hyperbloom Enabler	Sigewinne, Furina, Nahida, Raiden Shogun (EM)	Furina & Sigewinne provide Hydro for Blooms, which Raiden triggers. Sigewinne heals through Furina's HP drain and buffs Raiden's Skill.
Electro-Charged Support	Sigewinne, Fischl, Beidou, Kazuha	Sigewinne buffs Fischl's Oz and Beidou's Tidecaller (initial cast) while providing consistent healing and Hydro application for reactions.
Bond of Life Synergy	Sigewinne, Clorinde, Chevreuse, Fischl	A more niche but fun overload team where Sigewinne helps manage Clorinde's Bond of Life while buffing off-field Electro Skills.

Skill Priority: Which Talent Gets the Medicine First?

Resources are scarce, so where should you invest?

1. Elemental Skill (Priority #1): The main priority among Sigewinne's Talents is her Elemental Skill. This is her bread-and-butter healing ability. Max this out first.

2. Elemental Burst (Priority #2): Upgrade this next. It's a damage-dealing Burst that you'll use in your rotation, so you want it to hit decently hard.

3. Normal Attack (Priority #3 - Ignorable): You can leave this at level 1. You'll almost never use it.

In summary, building Sigewinne is refreshingly straightforward. Even without a dedicated 4-star HP bow, her healing potential, simple stat requirements, and team flexibility make her a remarkably reliable and valuable addition to any roster. So, equip your Recurve Bow or her signature Silvershower, slap on some Song of Days Past artifacts, and let the Melusine medic work her magic—your team will be in safe hands. 🩹✨
