SUPPORT Build 👍
Support Kokomi focuses on just using her Elemental Burst before her Elemental Skill's duration ends to refresh her skill duration. This allows 100% uptime on Hydro application from her Elemental Skill for Freeze / Electro-charge teams. Regarding Weapon Choices: Hakushin Ring: This weapon can provide Elemental DMG% for the team in Electro-charged teams and will outperform Prototype Amber if you value damage more than healing. Sacrificial Fragments: Can be useful as Kokomi won't need to use her Elemental Burst to reset her skill duration. This allows for smoother rotations as she will not face the problem of missing out on the reset for her Elemental Skill due to not casting Burst in time. Regarding Artifact Sets: Tenacity of the Millelith (4): With proper extension of Kokomi's Elemental Skill, she can maintain near 100% uptime on this artifact set's 4 piece effect. Ocean Hued Clam (4): This ranking assumes Kokomi is being used only for her Elemental Skill. If she is being used to attack onfield during Elemental Burst, this set may overtake Tenacity of the Millelith (4). Regarding Main Stats and Sub Stats: Energy Recharge: Prioritise Energy Recharge first to ensure you can always use Elemental Burst before the Elemental Skill expires in order to maintain Hydro application. Mainstats are not important for Tenacity of the Millelith (4) if you do not need the extra healing. Focus on Energy Recharge substats instead.
ABILITY TIP
Kokomi's Elemental Burst dynamically alters her skill's damage, this means that you cannot use her Burst to snapshot the buff onto the Skill and swap out.

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.
