Support Healer Kokomi Build

Kokomi's classic build is that of a healer, primarily focusing on stats which boost your healing to ensure your team stays alive. Thanks to her incredible Hydro application however, she also effectively support reaction teams such as Freeze teams.

  3. Normal Attack

Thrilling Tales of Dragon Slayers is a really good weapon for Kokomi due to the damage buff it provides for the entire party. Sacrificial Fragments is an interesting weapon and can allow you to refresh your Elemental Skill Kurage's Oath without having to use Nereid's Ascension giving you guaranteed uptime while removing any energy issues.

Tenacity of the Millelith and Ocean-Hued Clam are both incredibly similar artifact sets in terms of how good they are for Kokomi. With Tenacity of the Millelith providing a damage buff to further increase your teams damage while Ocean-Hued Clam instead provides personal damage when healing. Ocean-Hued Clam is better if you plan to stay on field and attack while using Nereid's Ascension.


Bloom DPS Kokomi Build

In Bloom teams, Kokomi is often the main trigger for a lot of reactions and therefore wants different artifact sets as well as having different stat priorities which instead focus on increasing the damage of Bloom reactions.

BiS Weapon A Thousand Floating Dreams
Alternative Weapons
  1. Sacrificial Fragments
  2. Magic Guide
  3. Fruit of Fulfillment
Best Artifacts
  1. Flower of Paradise Lost
Main Stats
  • Sand Stats: Elemental Mastery
  • Goblet Stats: Elemental Mastery
  • Circlet Stats: Elemental Mastery
Substat Priority
    1. Elemental Mastery
    2. Energy Recharge
    3. HP %
    4. HP
Talent Priority
  1. Elemental Skill
  2. Elemental Burst
  3. Normal Attack

As a Bloom DPS, Kokomi will be triggering a large majority of the bloom reactions and subsequently needs a lot of Elemental Mastery to increase that damage. This is why weapons such as A Thousand Floating Dreams and Sacrificial Fragments are great options for her.

Due to the focus on Bloom reactions with this build, Flower of Paradise Lost is a great artifact set for Kokomi as it increases reaction damage.


DPS Kokomi Build

On top of the other 2 builds, Kokomi can also be played as an on-field DPS. While previously a more Niche option, it can now be quite powerful with the release of Furina which has enabled Mono Hydro team compositions.

BiS Weapon Everlasting Moonglow
Alternative Weapons
  1. Prototype Amber
  2. Hakushin Ring
  3. Thrilling Tales of Dragon Slayers
Best Artifacts
  1. Ocean-Hued Clam
Main Stats
  • Sand Stats: HP % / Energy Recharge
  • Goblet Stats: Hydro DMG
  • Circlet Stats: Healing Bonus
Substat Priority
    1. HP %
    2. Energy Recharge
    3. ATK %
    4. HP
Talent Priority
  1. Elemental Burst
  2. Normal Attack
  3. Elemental Skill

As a DPS, this build will focus to increase her on-field damage during her Elemental Burst, Nereid's Ascension, which increases Kokomis damage based on her max Hp. Because of this her signature weapon Everlasting Moonglow is her best weapon.

Ocean-Hued Clam is her best artifact set due to it also being able to increase your teams damage through healing.


Combos and How to Play Kokomi

Kokomi's playstyle mainly involves her Bake-Kurage summoned using Kurage's Oath to apply Hydro for reactions and heal the party. This has incredibly powerful hydro application due to having no internal cooldown. The duration of Bake-Kurage can also be extended when using Nereid's Ascension allowing for constant uptime.

When playing as a DPS, it is more damage to do your Normal Attack, Normal Attack: The Shape of Water twice (or 3 times at C1) and then dash cancel the animation to be able to attack again.


Kokomi's Best Team Comps

As an extremely powerful healer, Kokomi can be used in a very wide range of team compositions. On top of simply being a healer, Kokomi can work in reaction-based comps to also increase their damage.


Kokomi Freeze Teams

Main DPS Sub DPS Support Anemo CC
Kamisato Ayaka Shenhe Sangonomiya Kokomi Kaedehara Kazuha Venti

In Freeze teams, Kokomi provides impressive AoE Hydro application so that Cryo characters such as Kamisato Ayaka can consistently maintain Freeze. Anemo characters such as Kaedehara Kazuha and Venti can help support the team by providing off-field damage and crowd control as well as the benefits of the Viridescent Venerer artifact set.


Kokomi Hyperbloom Team

Main DPS Sub DPS Sub DPS Support
Nahida Yelan Kuki Shinobu Sangonomiya Kokomi

In Hyperbloom team compositions, Kokomi can apply Hydro to Dendro so that an Electro character such as Kuki Shinobu or Raiden Shogun can trigger Hyperbloom reactions to deal massive damage.


Nilou Bloom Team

Nilou Nahida Dendro Traveler Sangonomiya Kokomi

Kokomi has great synergy with Nilou providing powerful healing to keep your party alive during Bloom damage. Your Bake-Kurage will apply a large portion of the Hydro damage however you may need to use Kokomi to apply additional Hydro occasionally.

Because Kokomi will be triggering a lot of the Bloom reactions, it is advised to equip her with Flower of Paradise Lost with a focus on Elemental Mastery.


Mono Hydro Team

While previously viable, Furina helps to make Mono-Hydro a powerful team composition. In this team, Kokomi plays the role of the main on-field damage dealer while Furina, Xingqiu and Yelan all provide powerful off-field damage. Additionally, Mono Hydro teams benefit from Hydro Resonance as well as low Energy Requirements due to everyone sharing the same Element.
