Best Party Members to match Kokomi with in Genshin Impact

Premium (Gacha) Team

In Genshin Impact, Kokomi is a great sub-DPS that can spread out Hydro on the field and set up for reactions from the rest of the team. Use Venti to control enemies and help spread the Hydro around. Ayaka can do the most damage here as she can freeze enemies hit by Hydro and naturally delivers heavy Cryo damage. Use Raiden to boost energy recovery and cause reactions.

F2P Team

Kokomi will be used to cause reactions with the Electro members of the team and heal as a sub-DPS. Pair her up with Kaeya to freeze enemies and do additional damage. Electro Traveler can drop Electro on the field and recover energy to keep Kokomi’s Burst nearby. Lisa is a great choice for using as your DPS when there’s Hydro on the field.
