Kokomi will be both your Sub-DPS and healer, alongside Diona.

Free to Play

If you have unlocked the Inazuma region and have the Electro Traveler, you can use Kaeya and Lisa alongside Kokomi to create a Superconduct team. Kaeya can free enemies while Lisa and the Electro traveler will be your main DPS. Kaeya is also a great battery for the team. Kokomi will act as your healer and Hydro applicator to enemies, allowing for an Electro-charged elemental reaction.

Electro Charged Team

This team focuses on defeating multiple enemies at once.

Both Kokomi and Fischl do not have to be on the field to apply the Hydro and Electro elements on enemies. Kokomi can also constantly heal Beidou without being on the field.

Kokomi does not have to be on the field to apply the Hydro element on enemies as well.
