Vodyanitsa is a five-star Hydro Catalyst support who arrived in Phase 1 of Version 7.1 on September 23, 2026, sharing a banner window with Vesna that runs through October 13, 2026. Her whole kit runs on Max HP, she needs almost no field time, and she hands out healing, interruption resistance, and resistance shred for three elements. Voiced by Suzie Yeung in English and Ito Kanae in Japanese, she is one of the easiest premium supports to build and one of the most flexible to slot, provided you feed her the right HP number.
Quick answer: Put HP% on her Sands, Goblet, and Circlet to aim for about 65,000 HP; use 4-piece Tenacity of the Millelith, prioritize her Elemental Skill for a crown, and pair her with Freeze or Stellar Swirl teams.
Why Max HP is the only stat that counts
Every buff Vodyanitsa provides scales off her Max HP, but nothing begins working until she passes 40,000 HP. Above that point, each 1,000 HP adds more flat damage to Hydro and Cryo attacks, and the gains keep climbing until about 65,000 HP. Hitting that mark finishes her bonuses for Hydro, Cryo, and Stellar Swirl at once; anything beyond it does nothing for her passives.
Aim for 60,000 HP during artifact farming, with 65,000 as the later goal. You can skip Energy Recharge because her Burst adds little to her role. If you choose to cast it, though, its cost is one of the game’s lowest, so a modest amount of Energy Recharge is enough.
Elemental Skill, Burst, and talent priority
Most of her value comes from Rechitativ: Sonorous Dawn, her Elemental Skill. Its effect remains on the character currently on the field when Vodyanitsa swaps out, dealing Hydro about every three seconds. It also reduces enemy Hydro and Cryo RES by as much as 30%, heals, and provides interruption resistance. Make this her first talent priority and crown it.
Her Burst, Sink With Thee, deals cheap AoE Hydro damage that adds little to her support role, so most rotations skip it. Normal Attack, Psyshkhwe Arietta, can stay at level 1. Talent order is Elemental Skill, then Elemental Burst if you use it, then Normal Attack last.
The Last Djeguako Songstress and Dirge of the Fandyr are the two passives that complete her kit. While her Skill is running, The Last Djeguako Songstress lowers nearby Anemo RES by 35%, enabling her role on Stellar Swirl teams. Dirge of the Fandyr creates HP-based stacks to boost Hydro, Cryo, and Stellar Swirl damage.
Best artifacts for Vodyanitsa
Since her personal damage is negligible, artifact choices should push HP and team buffs. Run HP% on the Sands, Goblet, and Circlet, and prioritize HP% substats, then flat HP, then Energy Recharge. A Healing Bonus circlet works only when you need extra sustain, and the lost buff power usually outweighs the healing.
| Set | Bonus that matters | Best for |
|---|---|---|
| Tenacity of the Millelith (4pc) | +20% HP, +20% team ATK | Default pick |
| 2pc Tenacity + 2pc Vourukasha’s Glow | +20% HP, +20% HP | Reaching 65,000 HP |
| Song of Days Past (4pc) | +15% Healing, damage from healing | Freeze teams |
| Instructor (4pc) | +120 team EM | Early filler only |
Tenacity of the Millelith is the standard pick: its two-piece bonus advances her HP target, and its four-piece effect gives the party 20% ATK when her off-field Hydro damage connects—a trigger her Skill provides reliably. ATK-scaling Stellar Swirl and Freeze carries benefit especially well. If another teammate has Tenacity equipped, pair two HP-boosting two-piece sets instead. Song of Days Past converts her regular healing into damage, making it a good fit for Freeze teams. Instructor should be a last resort; giving up the HP from a four-star set noticeably weakens her buffs.
Best weapons for Vodyanitsa
All the worthwhile catalysts share a large HP substat to help her approach the cap; their passives are what set them apart.
| Weapon | HP substat | Source |
|---|---|---|
| Hymn of the Maelstrom | 66.2% | Signature (gacha) |
| Jadefall’s Splendor | 49.6% | Gacha |
| Everlasting Moonglow | 49.6% | Gacha |
| Prototype Amber | 41.3% | Crafted |
| Ash-Graven Drinking Horn | 41.3% | Event |
| Thrilling Tales of Dragon Slayers | 35.2% | Gacha (3-star) |
Hymn of the Maelstrom is her signature weapon and best-in-slot choice. Healing raises her Max HP and Healing Bonus, while each 1,000 HP above 40,000 is converted into ATK for the active character. If an ally triggers Frozen or Stellar Swirl, the weapon’s stacks gain 75%; these are her two main archetypes, and the buff persists off-field as characters swap.
Thrilling Tales of Dragon Slayers remains a strong free choice. Its HP secondary stat helps her hit the cap; at R5, it grants the character taking over an ATK increase of 48% that lasts 10 seconds, which fits her brief rotation. Give this catalyst to only one party member, since identical switch-in effects cannot stack.
Prototype Amber is a forgeable choice to consider when her Burst is part of the plan, since its passive restores Energy and heals the party. Jadefall’s Splendor or Everlasting Moonglow can provide extra HP if you already own either one. Every 15 seconds, Ash-Graven Drinking Horn produces a modest area-of-effect strike that scales with Max HP, adding a little personal damage.
Best teams and post-release damage numbers
Vodyanitsa’s strongest homes are Freeze and Stellar Swirl, but she can also prop up ordinary Cryo and Hydro carries. Post-release testing across full teams produced the following totals, which give a sense of where she meaningfully moves the needle versus where she is a sidegrade.
| Carry | Lineup | Tested team DPS |
|---|---|---|
| Sandrone | Sandrone, Odette, Sucrose, Vodyanitsa | 247k |
| Vesna | Vesna, Odette, Cryo Traveler, Vodyanitsa | 223k |
| Skirk | Skirk, Furina, Escoffier, Vodyanitsa | 187k |
| Mizuki | Mizuki, Odette, Cryo Traveler, Vodyanitsa | 187k |
| Lohen | Lohen, Escoffier, C4 Mona, Vodyanitsa | 164k |
| Varka | Varka, Prune, Furina, Vodyanitsa | 159k |
| Chasca | Chasca core with Vodyanitsa | 133k |
| Neuvillette | Neuvillette core with Vodyanitsa | 133k |
Skirk Freeze
Skirk, Furina, Escoffier, and Vodyanitsa form her signature Freeze lineup. Vodyanitsa meets Skirk’s requirement for a roster made entirely of Cryo and Hydro units; her healing sustains Furina’s Burst bonus, and she further reduces both Hydro and Cryo resistance. Compared with C2 Shenhe or C4 Mona setups, she adds roughly 23k–25k DPS and performs about 7% better than Citlali in the fourth slot. Skirk can be replaced by Ayaka, Wriothesley, Ganyu, or Neuvillette, while Yelan or Xingqiu can fill Furina’s position.
Keep Escoffier on the team; Vodyanitsa is not her substitute. Removing Escoffier cuts the team’s damage. Use Vodyanitsa in place of Citlali, Shenhe, or Mona.
Vesna Stellar Swirl
Vesna, Odette, Cryo Traveler, and Vodyanitsa build around her strengths. By turning Cryo Swirl into Stellar Swirl, Vesna activates the Anemo shred; Odette supplies off-field Cryo and Stellar Glimmer, while Cryo Traveler keeps reactions going. Vodyanitsa brings healing and RES reduction. For your carries, choose ATK% and CRIT goblets instead of elemental DMG%, since Stellar Swirl follows the Lunar Reactions formula and disregards elemental DMG bonuses. She performs around C6 Faruzan’s level here, exchanging some buff power for sustain, and can come out slightly ahead of Faruzan in the third or fourth slot.
Sandrone, Lohen, and Varka variants
Sandrone works as a Stellar Swirl carry; with Odette, Sucrose, and Vodyanitsa alongside her, the team gains Cryo shred, ATK from Tenacity and Thrilling Tales, and enemy grouping. Lohen’s Freeze team reaches about 164k team DPS with Escoffier and C4 Mona. Another option is Varka, Prune, Furina, and Vodyanitsa for a lighter Hydro lineup, with Mona as a Furina substitute. These alternatives fall short of her two primary archetypes, but remain viable if the units are already built.
Marginal cases: Mizuki, Chasca, and Neuvillette
For Mizuki she delivers only minor gains over Faruzan, and her constant Hydro can disrupt Swirl sequences that depend on a specific order. Chasca pairings came out underwhelming. For Neuvillette she offers only about a 1k–5k improvement over Ineffa teams, so she is a sidegrade at best there.
Where she does not fit, and how she moves in the overworld
Frequent Hydro reapplication is the main constraint on her team choices. In Pyro-carry Vaporize teams, she can repeatedly replace the aura and make reactions unreliable; teams that rely on precise Swirl sequences may also lose their planned reactions. Her consistent Hydro is either neutral or beneficial in Freeze, mono-Hydro, and Stellar Swirl lineups.
Exploration is modest. In her mermaid form she swims slowly across surface water, has no infinite water-walking, and consumes stamina normally, so she is not a traversal upgrade over existing swim options.
Constellations worth chasing
| Constellation | Effect | Verdict |
|---|---|---|
| C1 | Team ATK when she heals | Solid, minor |
| C2 | Hydro/Cryo and Stellar Swirl CRIT DMG, +9s Skill | Biggest jump |
| C4 | Stacking Max HP above 40% health | Helps hit the HP cap |
| C6 | C2 effects for the whole party, extra DMG | Full team buffer |
Set your constellation priority to C2 > C6 > C1. C2 is the major breakpoint: it adds nine seconds to her Skill, nearly eliminating downtime, and gives the carry a substantial CRIT DMG boost. C4 chiefly eases the HP requirement. With C6, the C2 effect reaches the entire party, along with added Stellar Swirl, Hydro, and Cryo damage.
Is Vodyanitsa worth pulling?
Vodyanitsa brings valuable utility, though teams do not require her. Healing, interruption resistance, and RES reduction for three elements all help, but her advantage over the supports available now is more limited than her kit might imply. She is a particularly good fit for Stellar Swirl-focused accounts, where she pairs naturally with Vesna, and for Skirk Freeze players with heavy investment, where she outperforms Citlali or Mona but remains behind Escoffier. She also works as an excellent Thrilling Tales holder and remains useful across nearly any roster, making her an easy support to justify if you already use Cryo or Hydro damage dealers.
