Sangonomiya Kokomi Skill Guide & How To Use Sangonomiya Kokomi

Recommended Rotation For Kokomi

	Recommended Rotation
1	Use Elemental Skill and switch to other characters
2	Use other characters to deal reactions her Elemental Skill
3	If the Elemental Skill is down, use her Elemental Burst
4	Use her Elemental Burst and use charged attacks near her Jellyfish
5	Once the Burst is over, repeat step 1

Uses Of Kokomi's Elemental Skill

Consistent Infliction Of Hydro At A Certain Area

▲Triggers reaction per Tic making it great for any reaction comps.

Kokomi summons a jellyfish that lasts for 12 seconds. This heals allies and damages enemies around it while dealing Hydro. The jellyfish does not disappear even if you switch character which makes it an amazing skill for triggering Hydro Elemental reactions.

Uses Of Kokomi's Elemental Burst

Resets The Duration Of Elemental Skill

Kokomi's Elemental Burst mainly has two roles depending on the role of Kokomi: First, is to refresh the duration of her Elemental Skill. For support Kokomi, the main role of Elemental Burst is to reset the Elemental skill enabling it to have an almost 100% uptime in the field.

Increases The DMG Capability Of Kokomi

The second role is to increase Kokomi's personal damage. Elemental Burst will increase the damage of Kokomi's skills that scales from her Max HP. The effects of this, however, disappears after switching characters.

Heals Team In Tics

While you are in Elemental Burst, each tic will heal the team. This can also increase the damage because of the artifact, Ocean-Hued Clam Set. The Elemental Burst of Kokomi combined with Elemental Skill can easily reach the max 30,000 of the artifact set.

Should You Pull for Sangonomiya Kokomi's Constellation Or Best Weapon?

Prioritize Sangonomiya Kokomi's C1

Signature VS Constellations
C1 > C4 or Everlasting Moonglow

C1 Is a Decent Damage Increase

The extra swimming fish generated from Kokomi's C1 contributes a fair amount of damage and also acts as another source of Hydro, making her on-field state after using her Burst more rewarding. Her C1 is arguably her most valuable constellation, with C4 and C6 being the next best, and is a good stopping point for most of Kokomi's use-cases.

Her Signature Weapon is typically not recommended, since the craftable Prototype Amber is almost as good. Kokomi's performance with her Signature Weapon is slightly better when she goes on-field more, but unless the other weapon on the banner is something you can realistically use, getting Everlasting Moonglow (and the rest of her constellations) is considerably lower on the pull priority list.

Sangonomiya Kokomi's Constellations & Effects

Rating	Constellation Effect

★★★・・	C3: The Moon, A Ship O'er The Seas Increases the Level of Nereid's Ascension by 3. Maximum upgrade level is 15.

★★・・・	C5: All Streams Flow To The Sea Increases the Level of Kurage's Oath by 3. Maximum upgrade level is 15.
