Introduction

Genshin Impact Kokomi, the Divine Priestess of Watatsumi Island, is a five-star Hydro Catalyst user renowned for her exceptional healing and support capabilities. Despite initial skepticism due to her passive talent, Flawless Strategy, which increases her Healing Bonus by 25% but reduces her CRIT Rate by 100%, Kokomi has proven to be a versatile and reliable character in various team compositions.

Her Elemental Skill, Kurage’s Oath, summons a Bake-Kurage that provides continuous healing to allies while applying Hydro to enemies, making her an excellent enabler for Elemental Reactions like Freeze and Electro-Charged. Her Elemental Burst, Nereid’s Ascension, enhances her Normal and Charged Attacks, scales off her Max HP, and grants her additional healing capabilities, allowing her to sustain her team while dealing consistent damage. To maximize her potential, building Kokomi with HP%, Healing Bonus, and Energy Recharge is crucial, as her abilities scale primarily with HP.

The Ocean-Hued Clam artifact set boosts her healing while providing additional damage, whereas Tenacity of the Millelith enhances her team’s overall strength. When paired with Electro characters like Fischl or Beidou, she excels in Electro-Charged teams, and with Cryo allies like Ayaka or Ganyu, she enables strong Freeze compositions. Additionally, her consistent Hydro application makes her an excellent choice for Vaporize teams alongside Pyro characters. Genshin Impact Kokomi is not only a top-tier healer but also a reliable enabler and sustain unit, making her an invaluable asset in both casual play and high-level content such as the Spiral Abyss.

Kokomi’s Abilities

Normal Attack: The Shape of WaterKurage’s OathNereid’s Ascension

Kokomi excels as a potent healer in Genshin Impact, offering both single-target and AoE healing to ensure team survivability. Her Elemental Skill, Kurage’s Oath, summons a Bake-Kurage that continuously heals active characters while dealing Hydro damage to enemies at regular intervals, scaling with her Max HP. This skill provides consistent Hydro application, making her an excellent enabler for Elemental Reactions.

Her Elemental Burst, Nereid’s Ascension, enhances her combat abilities by granting her a Ceremonial Garment, which increases her Normal and Charged Attack damage based on her Max HP while healing nearby party members with every hit. It also boosts her resistance to interruption, allowing her to sustain damage output even in chaotic battles. Additionally, during this state, Kokomi can walk on water, providing unique exploration utility in specific situations.

Beyond her role as a healer, Kokomi is an effective Hydro applicator, making her highly valuable in reaction-based teams such as Freeze, Electro-Charged, and Bloom. Her ability to apply Hydro consistently without relying on CRIT-based damage ensures reliable reaction triggers, particularly in compositions like the well-known “Sukokomon” team. However, her -100% CRIT Rate from her passive talent, Flawless Strategy, makes her an unconventional damage dealer, requiring a focus on stats like HP%, Healing Bonus, and Energy Recharge rather than traditional CRIT-based builds.

Managing her Energy Recharge can be crucial for maintaining uptime on her Elemental Burst, especially in teams that require sustained healing and Hydro application. With multiple viable artifact sets, including Ocean-Hued Clam for additional damage or Tenacity of the Millelith for team buffs, optimizing Kokomi for different team compositions can require careful resource investment. Despite her unique mechanics, Kokomi remains a versatile and reliable character who excels in both casual exploration and high-level combat scenarios.

5-Star Weapons
Kokomi does not have a dedicated 5-star weapon for Bloom DPS, but Everlasting Moonglow can still be used for its HP and Energy regeneration.

4-Star Weapons
Sacrificial Fragments is the best weapon for Bloom DPS Kokomi, as its Elemental Mastery substat increases reaction damage and its passive helps reset Elemental Skill cooldowns for more Hydro application. Prototype Amber remains a solid alternative, offering HP and Energy generation for sustained Elemental Burst uptime.

3-Star Weapons
There are no 3-star weapons that significantly boost Bloom DPS Kokomi due to the lack of Elemental Mastery-focused options.

Best Team Compositions for Kokomi

AyakaGanyuKazuhaVentiShenheRosaria

Freeze Teams Kokomi excels in Freeze teams by providing consistent Hydro application and healing. A strong team includes Ayaka or Ganyu as the Cryo DPS, Kazuha or Venti for crowd control and Viridescent Venerer resistance shred, and Shenhe or Rosaria to enhance Cryo damage and energy generation. Kokomi’s Hydro application ensures enemies remain frozen, while her healing keeps the team sustained in prolonged fights.

FurinaYelanZhongli

Main DPS Kokomi Teams Kokomi can function as the main damage dealer when equipped with the Ocean-Hued Clam set, which converts healing into damage. A recommended team consists of Kokomi as the on-field attacker, Furina for additional Hydro damage and buffs, Yelan for off-field DPS, and Zhongli for shielding and resistance shred. This setup maximizes Kokomi’s personal damage while maintaining team survivability.

NahidaAlhaithamShinobuRaiden Shogun

Hyperbloom Teams Kokomi is a key enabler in Hyperbloom teams, ensuring consistent Hydro application to generate Dendro Cores. A strong lineup includes Nahida or Alhaitham for Dendro application, Kuki Shinobu or Raiden Shogun for Electro triggers, and Kokomi for healing and Hydro infusion. This composition allows for continuous Hyperbloom reactions, dealing powerful single-target damage.

NilouNahida

Nilou Bloom Teams Kokomi pairs exceptionally well with Nilou in Bloom teams, where her healing offsets the self-damage from Bountiful Cores. A recommended setup features Nilou and Nahida or the Dendro Traveler for Dendro application, Kokomi for Hydro support and healing, and another Dendro character to maximize core generation. Kokomi’s ability to sustain the team makes her one of the best choices for Nilou-centric compositions.

KleeDilucXiangling

Vaporize Teams Kokomi can function as a Hydro enabler in Vaporize teams, though careful rotation is needed to ensure Pyro characters trigger the reaction efficiently. A viable team includes Klee or Diluc as the main Pyro DPS, Kazuha for elemental buffs and resistance shred, Xiangling for off-field Pyro application, and Kokomi for sustained Hydro application and healing. While other Hydro units may offer stronger reaction consistency, Kokomi provides excellent survivability in aggressive Vaporize setups.

To fully ascend Sangonomiya Kokomi and upgrade her talents in Genshin Impact, you will need a variety of materials sourced from bosses, enemies, and domains across Inazuma. Her character ascension requires Varunada Lazurite stones in increasing rarities, which are obtained from Hydro Hypostasis, Oceanid, and Azhdaha. She also needs Dew of Repudiation, a boss material dropped by Hydro Hypostasis, along with Sango Pearl, a local specialty found exclusively on Watatsumi Island.

Additionally, you must collect Spectral materials—Spectral Husk, Spectral Heart, and Spectral Nucleus—by defeating Specter enemies. To reach level 90, you will need 1 Varunada Lazurite Sliver, 9 Fragments, 9 Chunks, and 6 Gemstones, along with 46 Dew of Repudiation, 168 Sango Pearl, 18 Spectral Husk, 30 Spectral Heart, and 36 Spectral Nucleus. The total Mora cost for ascension is 420,000.

Her ascension progresses through six ranks. At Rank 1 (Level 20), you need 1 Varunada Lazurite Sliver, 3 Sango Pearl, 3 Spectral Husk, and 20,000 Mora. Rank 2 (Level 40) requires 3 Varunada Lazurite Fragment, 2 Dew of Repudiation, 10 Sango Pearl, 15 Spectral Husk, and 40,000 Mora. Rank 3 (Level 50) needs 6

Varunada Lazurite Fragment, 4 Dew of Repudiation, 20 Sango Pearl, 12 Spectral Heart, and 60,000 Mora.

Kokomi’s talent materials focus on the Transience talent book series, which includes Teachings, Guide, and Philosophies of Transience, obtained from the Violet Court domain on Mondays, Thursdays, and Sundays. Each of her three talents—Kurage’s Oath, Nereid’s Ascension, and The Shape of Water—requires 3 Teachings, 21 Guide, and 38 Philosophies of Transience to reach level 10. Additional materials include 6 Spectral Husk, 22 Spectral Heart, and 31 Spectral Nucleus per talent, along with 6 Hellfire Butterflies dropped by La Signora and 1 Crown of Insight. The total Mora cost per talent to level 10 is 1,652,500.

For optimal performance, Kokomi’s recommended talent leveling order prioritizes Kurage’s Oath (Elemental Skill) first, followed by Nereid’s Ascension (Elemental Burst), and lastly her Normal Attack: The Shape of Water. While her talents cap at level 10 through standard upgrades, constellations can increase them further. Constellation 3 raises the level of Nereid’s Ascension, and Constellation 5 increases the level of Kurage’s Oath, both by 3 levels. This combination of ascension and talent investments ensures Kokomi is fully optimized for her role as a powerful Hydro healer and support character.

Maximum level 15.C6 – Sango IsshinGrants a 40% Hydro DMG Bonus for four seconds when Normal or Charged Attacks heal characters with 80% or more HP under Nereid’s Ascension. Boosts Kokomi’s on-field damage potential.

Sangonomiya Kokomi’s constellations offer a variety of enhancements to her healing, damage output, and Hydro application, making her more effective in both supportive and offensive roles depending on how she is built.

Her first constellation, At Water’s Edge, adds a unique offensive boost while she is under the effect of her Elemental Burst, Nereid’s Ascension. During this state, the final hit of her Normal Attack combo releases a swimming fish that deals Hydro damage equal to 30% of her Max HP. This damage is not considered Normal Attack damage, which means it is unaffected by effects that enhance Normal Attack DMG but benefits from Hydro and HP scaling. This constellation increases Kokomi’s on-field DPS and contributes to consistent Hydro application.

The second constellation, The Clouds Like Waves Rippling, enhances Kokomi’s healing for characters with 50% HP or less. When this condition is met, her Bake-Kurage from Kurage’s Oath heals an additional 4.5% of her Max HP, while her Normal and Charged Attacks during Nereid’s Ascension heal for an additional 0.6% of her Max HP. While this constellation offers a healing boost, it is conditional and only activates when allies fall below half health.

Constellation three, The Moon, A Ship O’er the Seas, increases the level of Kokomi’s Elemental Burst, Nereid’s Ascension, by three, up to a maximum of level 15. This directly enhances the healing and damage output of her Burst, which is central to her performance as both a healer and a hybrid DPS.

Her fourth constellation, The Moon Overlooks the Waters, improves Kokomi’s Normal Attack speed by 10% while under the effects of Nereid’s Ascension. Additionally, her Normal Attacks restore 0.8 Energy every time they hit an enemy, with a cooldown of 0.2 seconds. This allows her to generate energy more effectively and maintain a smooth rotation with higher Burst uptime.

Constellation five, All Streams Flow to the Sea, increases the level of her Elemental Skill, Kurage’s Oath, by three, also up to a maximum of level 15. This further enhances the healing and periodic Hydro damage of her Bake-Kurage, making her off-field support even stronger.

Her sixth constellation, Sango Isshin, grants Kokomi a 40% Hydro DMG Bonus for four seconds whenever her Normal or Charged Attacks heal, or would heal, a character with 80% or more HP while under the effect of Nereid’s Ascension. This includes healing characters who are already at full health. This final constellation significantly boosts her on-field damage potential, making Kokomi a more potent hybrid unit with strong sustained Hydro application and healing.

Gameplay and Combos

Sangonomiya Kokomi is a 5-star Hydro character who excels as a healer while offering consistent Hydro application and utility in elemental reaction teams. Although her passive talent, Flawless Strategy, reduces her CRIT Rate by 100%, it provides a 25% Healing Bonus, reinforcing her role as a support. Her abilities scale with Max HP, and her gameplay revolves around maximizing healing and reaction uptime through her Elemental Skill and Elemental Burst. Kokomi’s Normal Attack sequence consists of up to three Hydro-based attacks, with her Charged Attack dealing AoE Hydro damage. While she has high Energy Recharge demands, her consistent field presence makes her a reliable source of healing and Hydro status application.

Her Elemental Skill, Kurage’s Oath, summons a Bake-Kurage jellyfish that periodically deals Hydro damage and heals the active character, both based on Kokomi’s Max HP. The jellyfish lasts 12 seconds with a 20-second cooldown and applies the Wet status to Kokomi upon casting. Only one Bake-Kurage can exist at a time. Thanks to her Ascension Passive, Tamakushi Casket, using her Elemental Burst while the Bake-Kurage is active refreshes its duration. The jellyfish applies Hydro with each tick and does not have an internal cooldown, allowing it to trigger frequent elemental reactions.

Kokomi’s Elemental Burst, Nereid’s Ascension, deals Hydro damage and envelops her in a Ceremonial Garment for 10 seconds. While active, her Normal Attack, Charged Attack, and Bake-Kurage damage are increased based on her Max HP. Hitting enemies with Normal and Charged Attacks restores HP to the entire party, also scaling with her Max HP. During this state, Kokomi gains increased resistance to interruption and can walk on water. These effects are removed when she leaves the field. The Burst also resets the duration of the Bake-Kurage if it’s active, enabling uninterrupted healing and Hydro application. With an 18-second cooldown and 70 Energy Cost, this skill is central to her healing and damage rotation.

Kokomi’s general combo involves using Kurage’s Oath to summon the jellyfish, then rotating to teammates to trigger reactions. When the jellyfish’s duration nears its end, she casts Nereid’s Ascension to refresh it and enter the enhanced state. While the Ceremonial Garment is active, she remains on the field, using Normal and Charged Attacks to deal damage and provide team-wide healing. For on-field play, especially at Constellation 1, performing two to three Normal Attacks followed by a dash cancel optimizes DPS. In a support build, her talent leveling priority is Elemental Skill first, followed by Elemental Burst. In a DPS setup, the priority shifts to Elemental Burst, then Normal Attack, and lastly Elemental Skill.

Kokomi is highly flexible in team compositions. In Freeze teams, she maintains continuous Hydro application for Cryo reactions. In Hyperbloom teams, her jellyfish activates Dendro Cores that an Electro unit can detonate. In Nilou Bloom setups, she enables Bountiful Core creation while sustaining the team with healing. As part of Mono Hydro lineups, she can be an effective on-field DPS. In Electro-Charged teams, her consistent Hydro ticks work seamlessly with Electro characters to maintain the reaction.

A basic rotation begins with casting Kurage’s Oath to deploy the Bake-Kurage, switching to other units to activate elemental reactions. When the jellyfish is about to expire, Kokomi uses Nereid’s Ascension to refresh its duration and boost her damage. During the Burst, she attacks to heal and deal damage, remaining near the jellyfish for additional Hydro application. After the Burst ends, the rotation repeats. Constellation 4 enhances her effectiveness by increasing her Normal Attack speed by 10% and restoring 0.8 Energy every time her Normal Attacks hit enemies during her Burst, improving energy recovery and allowing for more consistent ability uptime.

A Glimpse into Kokomi’s Lore

Sangonomiya Kokomi is the Divine Priestess of Watatsumi Island and serves as its highest authority. As a descendant of the Sangonomiya Clan, she carries the legacy and will of the serpent god Orobaxi, dedicating herself to protecting the island and its people. Though she appears young, Kokomi quickly earned the respect of her people through her fairness, intelligence, and strategic brilliance. She is widely known as a master tactician whose foresight and ability to predict enemy movements helped lead the Watatsumi Army to several key victories during the Vision Hunt Decree conflict. Despite being outmatched in numbers and equipment, Kokomi’s clever planning gave her forces the edge they needed, earning recognition even from opponents like Kujou Sara.

Kokomi’s approach to strategy is deeply rooted in her extensive study of military treatises, which she began reading at a young age. Her strategic style is known for minimizing losses and turning disadvantages into advantages by controlling the broader battlefield. This same methodical thinking is also applied to her governance, as she balances military, diplomatic, and domestic affairs with careful consideration.

Although she performs her leadership duties with dedication, Kokomi does not relish the spotlight. Her true aspiration is to be an advisor working quietly behind the scenes, and she often finds social interactions exhausting. To cope with this, she follows a personal energy management system, taking time to rest and recharge through solitary activities, often involving more reading and analysis.

Kokomi is deeply committed to her people, and her leadership during the Vision Hunt Decree solidified her image as a protector of Watatsumi. After the conflict, she focused on rebuilding and improving the lives of her citizens through economic reform and stable governance. Her wish has always been to ensure peace and happiness for the people of the island. This unwavering dedication has made her a beloved figure, and a popular saying among the people is, “Never fear, Her Excellency Sangonomiya is here.”

Her constellation, Dracaena Somnolenta, or “Sleeping Dragoness,” is thought to echo the legacy of the famed Chinese strategist Zhuge Liang, known as the “Crouching Dragon.” This parallel underscores Kokomi’s identity as a hidden genius and quiet force of leadership. Even her gameplay reflects this uniqueness—she is the first character with a negative base CRIT Rate, highlighting her non-traditional role that favors healing and support over burst damage. This design reinforces the idea that her true strength lies not in flashy power, but in quiet, strategic mastery and steadfast care for those she leads.
