Genshin Sangonomiya Kokomi Build & Teams: 5-Star Hydro Catalyst Healer · Ocean-Hued Clam
Quick Answer
- Kokomi is a 5★ Hydro Catalyst (Inazuma priestess of Watatsumi) who heals and sub-DPSes; core = Bake-Kurage jellyfish for sustained healing + off-field Hydro.
- Core artifacts: Ocean-Hued Clam 4pc (overflow healing → foam damage) or Tenacity of the Millelith 4pc (team ATK buff); use Flower of Paradise Lost 4pc for Bloom.
- Main stats: HP% Sands / HP% or Hydro DMG Goblet / Healing Bonus Circlet.
- Substats: HP% > Energy Recharge > EM (Bloom teams).
- Key: her passive "Flawless Strategy" sets CRIT Rate to −100% — never build CRIT; pour everything into HP and ER.
- Best teams: Kokomi + Ayaka + Shenhe + Kazuha (Freeze), Kokomi + Nilou + Nahida + Baizhu (Bloom).
- Weapon "Everlasting Moonglow" fits best; F2P use "Prototype Amber" or "Thrilling Tales of Dragon Slayers" (3★).
Role & Kit
Kokomi's value is steady Hydro application plus reliable healing:
- Skill "Bake-Kurage": summons a jellyfish that heals the team and applies off-field Hydro — the heart of Ocean-Hued Clam and Bloom triggers.
- Burst "Ceremonial Garment": boosts NA/CA/jellyfish damage based on Max HP and refreshes the jellyfish duration.
- A4 "Song of Pearls" converts 15% of Healing Bonus into NA/CA damage bonus — that is why the circlet is Healing Bonus.
- Stack HP and ER; zero CRIT needed.

FAQ
Is Kokomi still worth building?
Yes. She fits Freeze, Bloom, Hyperbloom and Taser; C0 is complete and she needs no CRIT, so she is easy to gear.
Should I build CRIT on Kokomi?
Absolutely not. Her passive sets CRIT Rate to −100%, so CRIT stats are wasted — invest in HP and ER only.
How much Energy Recharge?
On-field ~200%, with Prototype Amber down to ~160%; off-field ~140%.
What is her best weapon?
Everlasting Moonglow fits best; without a 5★ use Prototype Amber, or Thrilling Tales of Dragon Slayers (3★) for pure support.
What teams is she good in?
Freeze, Nilou Bloom, Hyperbloom and Taser all benefit from her steady Hydro + healing.
