Kokomi is a 5-star Hydro Catalyst user who stands as one of the most comfortable and reliable healers in Teyvat. She excels as a high-impact Support and Hydro Enabler, mostly because her Kurage's Oath skill allows her to deploy a Bake-Kurage that continuously heals your active unit while providing consistent area-of-effect Hydro application to enemies. In this guide, we're going over the best ways to gear her, which weapons actually maximize her utility, and whether her constellations are worth your hard-earned Primogems. Read on!

Kokomi Gameplay

Her gameplay centers around a highly reliable kit, which transforms her elegant combat style into a seamless blend of potent off-field Hydro application and absolute team survivability. Her kit primarily scales on her Max HP, which uniquely boosts both her damage output and her massive healing capabilities, and she enables highly flexible team compositions by providing constant elemental reactions and unparalleled defensive comfort.

Her Elemental Skill, Kurage's Oath, summons a water-based phantom known as a Bake-Kurage to heal allies and deal AoE Hydro DMG. When deployed, it remains stationary on the battlefield and pulses at regular intervals, actively restoring a massive amount of health to your current on-field character based on her Max HP, a mechanic heavily favored for keeping fragile DPS units alive; otherwise, it serves as her primary tool for continuous off-field Hydro application. This steady elemental presence ensures she can constantly enable powerful reactions like Bloom, Vaporize, or Permafreeze.

When she unleashes her Elemental Burst, Nereid's Ascension, she dons a Ceremonial Garment that instantly empowers her combat capabilities based on her Max HP, while dealing a burst of Hydro DMG to nearby enemies. It essentially turns her into a sturdy on-field driver, significantly boosting the damage of her Normal Attacks, Charged Attacks, and her deployed Bake-Kurage. The best part is that her attacks now actively heal all party members on hit, meaning she effectively brings the entire squad back to full health just by staying on the offensive, allowing your team to confidently stand their ground against the toughest enemies or domain modifiers.

Her Passives are all about doubling down on her unique scaling while ensuring her supportive utility is consistently available. One of them famously drops her CRIT Rate by 100% in exchange for a massive, permanent 25% Healing Bonus, while another directly refreshes the duration of her active Bake-Kurage the moment her Burst is cast to ensure you never have a gap in your elemental application. It makes her super satisfying to play because you're essentially bringing an unkillable tank who can keep the squad perfectly safe with a few simple attacks while effortlessly managing 100% uptime on her jellyfish.

Kokomi Talent Priority

Talent	Recommended Level
Elemental Skill (Kurage's Oath)	10+
Elemental Burst (Nereid's Ascension)	9+
Normal Attack (The Shape of Water)	6+

Elemental Skill - Kurage's Oath

This is her absolute most important ability. It deploys a Bake-Kurage that continuously restores a massive amount of HP to the active character based on her Max HP and provides steady area-of-effect Hydro application. Leveling this maximizes your team's survivability and her off-field Hydro damage, making it the absolute core of her supportive kit.

Elemental Burst - Nereid's Ascension

Her primary tool for team-wide healing and refreshing her jellyfish duration. It deals solid Hydro damage upon cast and significantly buffs her own attacks based on her Max HP. Leveling this increases her raw damage output and burst-healing capabilities, making her a much more potent on-field driver during your ultimate window.

Normal Attack - The Shape of Water

While her Burst state heavily empowers her standard strikes to heal the entire party on hit, the base scaling of the attacks themselves isn't high enough to warrant prioritizing this over her powerful Hydro abilities unless you are specifically building her for on-field DPS. For a standard off-field support and healing role, this is leveled last to optimize your resource management.

Kokomi Best Weapons

1. Weapon for Support / Off-Field Kokomi

When Kokomi is playing the role of an off-field support, her job is wonderfully simple: drop her jellyfish to keep the team healed and apply constant Hydro, then swap out to let your main damage dealers take over. In this playstyle, you aren't worried about her personal damage or Elemental Mastery. Instead, your primary focus shifts to maximizing her Max HP and Energy Recharge so her jellyfish heals for as much as possible and her Burst is always ready to refresh its duration. Because Kokomi spends so little time on the field here, the absolute best weapons for this build are those that provide massive utility or attack buffs to the rest of your squad the moment she tags out. Here are some weapon options listed for a Support / Off-Field Kokomi:

Recommended weapon options for Support / Off-Field Kokomi
Option 1	Thrilling Tales of Dragon Slayers (3★)	Base ATK: 401 Bonus Stat: HP +35.2% Weapon Effect (R5): When switching characters, the new character taking the field has their ATK increased by 48% for 10s. This effect can only occur once every 20s.
Option 2	Prototype Amber (4★)	Base ATK: 510 Bonus Stat: HP +41.3% Weapon Effect (R5): Using an Elemental Burst regenerates 6 Energy every 2s for 6s. All party members will regenerate 6% HP every 2s for this duration.
Option 3	Hakushin Ring (4★)	Base ATK: 565 Bonus Stat: Energy Recharge +30.6% Weapon Effect (R5): After the character equipped with this weapon triggers an Electro elemental reaction, nearby party members of an Elemental Type involved in the elemental reaction receive a 20% Elemental DMG Bonus for their element, lasting 6s. Elemental Bonuses gained in this way cannot be stacked.
Option 4	Everlasting Moonglow (5★)	Base ATK: 608 Bonus Stat: HP +49.6% Weapon Effect (R1): Healing Bonus increased by 10%, Normal Attack DMG is increased by 1% of the Max HP of the character equipping this weapon. For 12s after using an Elemental Burst, Normal Attacks that hit opponents will restore 0.6 Energy. Energy can be restored this way once every 0.1s.
Option 5	Sacrificial Fragments (4★)	Base ATK: 454 Bonus Stat: Elemental Mastery +221 Weapon Effect (R5): After dealing damage to an opponent with an Elemental Skill, the skill has a 80% chance to end its own CD. Can only occur once every 16s.

2. Weapon for Bloom Teams

When building Kokomi for a Bloom team, her priority shifts entirely. Instead of focusing heavily on Max HP for healing and personal damage, she needs to stack as much Elemental Mastery (EM) as possible to maximize the damage of the Dendro Cores she triggers. Because she is usually the one creating these explosive reactions on the field, her best picks for this playstyle focus heavily on boosting that EM stat while still providing enough baseline healing to keep your squad alive. Here are some weapon options listed for a Kokomi Bloom team:

Recommended weapon options for Kokomi Bloom
Option 1	Sacrificial Fragments (4★)	Base ATK: 454 Bonus Stat: Elemental Mastery +221 Weapon Effect (R5): After dealing damage to an opponent with an Elemental Skill, the skill has a 80% chance to end its own CD. Can only occur once every 16s.
Option 2	A Thousand Floating Dreams (5★)	Base ATK: 542 Bonus Stat: Elemental Mastery +265 Weapon Effect (R1): Party members other than the equipping character will provide the equipping character with buffs based on whether their Elemental Type is the same as the latter or not. If their Elemental Types are the same, increase Elemental Mastery by 32. If not, increase the equipping character's DMG Bonus from their Elemental Type by 10%. Each of the aforementioned effects can have up to 3 stacks. Additionally, all nearby party members other than the equipping character will have their Elemental Mastery increased by 40. Multiple such effects from multiple such weapons can stack.
Option 3	Wandering Evenstar (4★)	Base ATK: 510 Bonus Stat: Elemental Mastery +165 Weapon Effect (R5): The following effect will trigger every 10s: The equipping character will gain 48% of their Elemental Mastery as bonus ATK for 12s, with nearby party members gaining 30% of this buff for the same duration. Multiple instances of this weapon can allow this buff to stack. This effect will still trigger even if the character is not on the field.
Option 4	Magic Guide (3★)	Base ATK: 354 Bonus Stat: Elemental Mastery +187 Weapon Effect (R5): Increases DMG against opponents affected by Hydro or Electro by 24%.

3. Weapon for DPS / On-Field Driver

When Kokomi is taking the spotlight as an on-field DPS or driver, her playstyle revolves entirely around her Elemental Burst. While it is active, her Normal and Charged Attacks deal significantly increased damage based on her Max HP, and her attacks simultaneously heal the entire party. In setups like Taser (Electro-Charged), Mono-Hydro, or Vaporize teams, she stays on the field to drive off-field attacks from her teammates while face-tanking incoming damage. For this role, you want weapons that maximize her personal damage, Max HP, and Energy Recharge so she can burst off cooldown. Here are some weapon options listed for a DPS / On-Field Kokomi:

Recommended weapon options for DPS / On-Field Driver
Option 1	Everlasting Moonglow (5★)	Base ATK: 608 Bonus Stat: HP +49.6% Weapon Effect (R1): Healing Bonus increased by 10%, Normal Attack DMG is increased by 1% of the Max HP of the character equipping this weapon. For 12s after using an Elemental Burst, Normal Attacks that hit opponents will restore 0.6 Energy. Energy can be restored this way once every 0.1s.
Option 2	Prototype Amber (4★)	Base ATK: 510 Bonus Stat: HP +41.3% Weapon Effect (R5): Using an Elemental Burst regenerates 6 Energy every 2s for 6s. All party members will regenerate 6% HP every 2s for this duration.
Option 3	Jadefall’s Splendor (5★)	Base ATK: 608 Bonus Stat: HP +49.6% Weapon Effect (R1): For 3s after using an Elemental Burst or creating a shield, the equipping character can gain the Primordial Jade Regalia effect: Restore 4.5 Energy every 2.5s, and gain 0.3% Elemental DMG Bonus for their corresponding Elemental Type for every 1,000 Max HP they possess, up to 12%. Primordial Jade Regalia will still take effect even if the equipping character is not on the field.
Option 4	Hakushin Ring (4★)	Base ATK: 565 Bonus Stat: Energy Recharge +30.6% Weapon Effect (R5): After the character equipped with this weapon triggers an Electro elemental reaction, nearby party members of an Elemental Type involved in the elemental reaction receive a 20% Elemental DMG Bonus for their element, lasting 6s. Elemental Bonuses gained in this way cannot be stacked.
Option 5	Ash-Graven Drinking Horn (4★)	Base ATK: 510 Bonus Stat: HP +41.3% Weapon Effect (R5): When an attack hits an opponent, deal AoE DMG equal to 80% of Max HP at the target location. This effect can be triggered once every 15s.

Kokomi Best Artifacts and Stats

1. Support / Off-Field Kokomi

When playing off-field, Kokomi's primary goal is to keep your team healthy with her jellyfish while simultaneously buffing your main damage dealer. Because her jellyfish has a wide area of effect, pulses damage every two seconds, and can be kept on the field almost indefinitely by using her Elemental Burst to refresh its duration, she is one of the most reliable characters in the game at triggering artifact sets that provide constant team-wide buffs. Instead of focusing on her personal damage, this build turns her into the ultimate utility unit. She ensures your active character can comfortably face-tank enemy attacks without needing to dodge, all while enjoying a massive attack boost to maximize their own damage output.

Recommended Artifacts for Support / Off-Field Kokomi
Option 1	Tenacity of the Millelith (4-Piece)	2-PC: HP +20% 4-PC: When an Elemental Skill hits an opponent, the ATK of all nearby party members is increased by 20% and their Shield Strength is increased by 30% for 3s. This effect can be triggered once every 0.5s. This effect can still be triggered even when the character who is using this artifact set is not on the field.
Option 2	Ocean-Hued Clam (4-Piece)	2-PC: Healing Bonus +15%. 4-PC: When the character equipping this artifact set heals a character in the party, a Sea-Dyed Foam will appear for 3 seconds, accumulating the amount of HP recovered from healing (including overflow healing). At the end of the duration, the Sea-Dyed Foam will explode, dealing DMG to nearby opponents based on 90% of the accumulated healing. (This DMG is calculated similarly to Reactions such as Electro-Charged, and Superconduct, but is not affected by Elemental Mastery, Character Levels, or Reaction DMG Bonuses). Only one Sea-Dyed Foam can be produced every 3.5 seconds. Each Sea-Dyed Foam can accumulate up to 30,000 HP (including overflow healing). There can be no more than one Sea-Dyed Foam active at any given time. This effect can still be triggered even when the character who is using this artifact set is not on the field.
Recommended Stats and Sub-Stats
Main Stat	Sands: HP% or Energy Recharge Goblet: HP% Circlet: Healing Bonus
Sub Stat	Energy Recharge (ER%) > HP% > Flat HP > Elemental Mastery

2. Bloom Kokomi

In Dendro-focused Bloom teams, Kokomi’s artifact choice is a delicate balancing act between maximizing explosive reaction damage and ensuring your team survives those very same explosions. Because Bloom cores deal a portion of their damage back to your own characters, blindly stacking pure Elemental Mastery (EM) can often be a trap. Without sufficient healing, the self-inflicted damage from a constant stream of seeds can easily overwhelm your party before the enemies are even defeated.

Recommended Artifacts for Bloom Kokomi
Option 1	Flowers of Paradise Lost (4-Piece)	2-PC: Elemental Mastery +80 4-PC: The equipping character's Bloom, Hyperbloom, and Burgeon reaction DMG are increased by 40%. Additionally, after the equipping character triggers Bloom, Hyperbloom, or Burgeon, they will gain another 25% bonus to the effect mentioned prior. Each stack of this lasts 10s. Max 4 stacks simultaneously. This effect can only be triggered once per second. The character who equips this can still trigger its effects when not on the field.
Option 2	Gilded Dreams (4-Piece)	2-PC: Increases Elemental Mastery by 80. 4-PC: Within 8s of triggering an Elemental Reaction, the character equipping this will obtain buffs based on the Elemental Type of the other party members. ATK is increased by 14% for each party member whose Elemental Type is the same as the equipping character, and Elemental Mastery is increased by 50 for every party member with a different Elemental Type. Each of the aforementioned buffs will count up to 3 characters. This effect can be triggered once every 8s. The character who equips this can still trigger its effects when not on the field.
Option 3	Wanderer's Troupe (2-Piece)	2-PC: Increases Elemental Mastery by 80.
Option 3	Gilded Dreams (2-Piece)	2-PC: Increases Elemental Mastery by 80.
Recommended Stats and Sub-Stats
Main Stat	Sands: Elemental Mastery Goblet: EM (or HP% if you are dying to core explosions) Circlet: Elemental Mastery
Sub Stat	Elemental Mastery > HP% > Energy Recharge > Flat HP

3. DPS / On-Field Driver Kokomi

When Kokomi is staying on the field to use her Elemental Burst, her healing output skyrockets because her Normal Attacks are healing the whole team at once. You want an artifact set that weaponizes this massive amount of healing and turns it into raw damage.

Recommended Artifacts for DPS / On-Field Driver Kokomi
Option 1	Ocean-Hued Clam (4-Piece)	2-PC: Healing Bonus +15%. 4-PC: When the character equipping this artifact set heals a character in the party, a Sea-Dyed Foam will appear for 3 seconds, accumulating the amount of HP recovered from healing (including overflow healing). At the end of the duration, the Sea-Dyed Foam will explode, dealing DMG to nearby opponents based on 90% of the accumulated healing. (This DMG is calculated similarly to Reactions such as Electro-Charged, and Superconduct, but is not affected by Elemental Mastery, Character Levels, or Reaction DMG Bonuses). Only one Sea-Dyed Foam can be produced every 3.5 seconds. Each Sea-Dyed Foam can accumulate up to 30,000 HP (including overflow healing). There can be no more than one Sea-Dyed Foam active at any given time. This effect can still be triggered even when the character who is using this artifact set is not on the field.
Option 2	Heart of Depth (4-Piece)	2-PC: Hydro DMG Bonus +15%. 4-PC: After using an Elemental Skill, increases Normal Attack and Charged Attack DMG by 30% for 15s.
Recommended Stats and Sub-Stats
Main Stat	Sands: HP% Goblet: Hydro DMG Bonus Circlet: Healing Bonus (Her passive converts Healing Bonus into Damage)
Sub Stat	HP% > Energy Recharge > Flat HP > Elemental Mastery

Kokomi Best Team Compositions

You can focus on her crucial off-field Hydro application to keep enemies permanently frozen alongside strong Cryo damage dealers and Anemo crowd control. Alternatively, Kokomi truly shines in Dendro-focused teams by continuously generating Dendro cores alongside off-field Dendro applicators, where her massive healing output is essential to counter the self-inflicted damage caused by pure Bloom or Hyperbloom reactions. Finally, for Electro-Charged (Taser) compositions, Kokomi takes on a more active role as the on-field driver during her Elemental Burst, absorbing incoming attacks and healing the entire party while off-field Electro sub-DPS units continuously chain lightning damage between grouped enemies.

Kokomi Constellations

While Kokomi is a complete and exceptional character at C0, offering incredible healing and Hydro application, her constellations primarily provide meaningful boosts to her personal on-field damage and help manage her Energy requirements.

Constellation Performance

Constellation	Rating	Explanation
C1	★★★★☆	The final Normal Attack in her Burst combo unleashes a fish dealing 30% of her Max HP as Hydro DMG. A solid personal damage boost for on-field Kokomi.
C2	★★☆☆☆	Increases her healing output for characters under 50% HP. Since Kokomi's baseline healing is already incredibly potent, this is often considered overkill.
C4	★★★☆☆	Increases Normal Attack SPD by 10% and restores 0.8 Energy per hit during her Burst. Greatly improves her energy management and makes her attacks feel smoother.
C6	★★★☆☆	Grants a 40% Hydro DMG Bonus when healing allies who are at or above 80% HP during her Burst. A strong addition to her personal damage ceiling, though an expensive investment.

Conclusion

This comprehensive guide demonstrates Kokomi's position as one of Genshin Impact's premier 5-star Hydro Healers and enablers, bringing both deep lore significance as the Divine Priestess of Watatsumi Island and exceptional gameplay mechanics. Her unique Bake-Kurage healing, continuous area-of-effect Hydro application, and unmatched synergies in Freeze, Bloom, and Taser teams make her incredibly valuable for players seeking a versatile, high-utility anchor for their rosters. While she is exceptionally complete at C0, her constellations provide meaningful improvements to her on-field damage and energy management, with C1 being a particularly valuable stopping point.

To fully prepare for Kokomi's next arrival and maximize her potential, consider topping up Genshin Impact via LootBar to secure the Genesis Crystals and Primogems needed for her limited-time banners and signature weapon. Ensuring you have the character and her best-in-slot gear is the essential first step before you head into the world to farm the materials required for her ascension and talents.
