Elemental Skill
  • Description
  • Gameplay Notes
  • Advanced Properties
  • Attribute Scaling
  • Preview

Summons a "Bake-Kurage" created from water that can heal her allies.
Using this skill will apply the Wet status to Sangonomiya Kokomi.

Bake-Kurage
Deals Hydro DMG to surrounding opponents and heal nearby active characters at fixed intervals. This healing is based on Kokomi's Max HP.

  • When each of the first 6 hits hits at least one enemy, it generates 0.67 Elemental Particles.
    • Generate on average 0.67 × 6 = 4.02 elemental particles if all ticks hit an enemy.
  • The Bake-Kurage ticks every 2 seconds, for a total of 7 times before its 12s duration ends. (including the initial hit)
  • Only one Bake-Kurage can exist at a time.
  • Ripple DMG will snapshot Sangonomiya Kokomi's stats on cast and will not be affected by changes in her stats that occur afterwards.
    • This will not be updated when the Bake-Kurage's duration is refreshed by her Passive Talent 1, Tamakushi Casket.
  • In most cases, the Additive Base DMG Bonus from Nereid's Ascension cannot be snapshotted by the Bake-Kurage; however, if Kurage's Oath is cast while Nereid's Ascension is active, and Kokomi leaves the field before the first Bake-Kurage tick, the Additive Base DMG Bonus can be snapshotted.
Passive Effects
  • Passive Talent 1, Tamakushi Casket Tamakushi Casket: "If Sangonomiya Kokomi's own Bake-Kurage are on the field when she uses Nereid's Ascension, the Bake-Kurage's duration will be refreshed."

Nereid's Ascension
Elemental Burst
  • Description
  • Gameplay Notes
  • Advanced Properties
  • Attribute Scaling
  • Preview
Summons the might of Watatsumi, dealing Hydro DMG to surrounding opponents, before robing Kokomi in a Ceremonial Garment made from the flowing waters of Sangonomiya.

Ceremonial Garment
  • Sangonomiya Kokomi's Normal Attack, Charged Attack and Bake-Kurage DMG are increased based on her Max HP.
  • When her Normal and Charged Attacks hit opponents, Kokomi will restore HP for all nearby party members, and the amount restored is based on her Max HP.
  • Increases Sangonomiya Kokomi's resistance to interruption and allows her to walk on the water's surface.

These effects will be cleared once Sangonomiya Kokomi leaves the field.
  • This Elemental Burst drains energy later than most others.[5]
  • Water essentially acts as if it were normal solid terrain for the duration of the burst. As such, while donning the Ceremonial Garment, Kokomi can take fall damage and even die if she jumps from a high distance onto water.
  • Kokomi will still take damage while walking on Electrified Water.
Passive Effects
  • Passive Talent 1, Tamakushi Casket Tamakushi Casket: refreshes the duration of Kokomi's Bake-Kurage upon casting Nereid's Ascension.
  • Passive Talent 2, Song of Pearls Song of Pearls: increases the Normal and Charged Attack DMG Bonus from Nereid's Ascension by 15% of Kokomi's Healing Bonus.
Constellation Effects
  • Constellation Level 1, At Water's Edge At Water's Edge: "While donning the Ceremonial Garment created by Nereid's Ascension, the final Normal Attack in Sangonomiya Kokomi's combo will unleash a swimming fish to deal 30% of her Max HP as Hydro DMG. This DMG is not considered Normal Attack DMG."
  • Constellation Level 2, The Clouds Like Waves Rippling The Clouds Like Waves Rippling: Increases the healing that nearby party members under 50% HP receive from Kokomi's Normal and Charged Attacks during Nereid's Ascension.
  • Constellation Level 3, The Moon, A Ship O'er the Seas The Moon, A Ship O'er the Seas: Increases this talent's level by 3, up to a maximum of 15.
  • Constellation Level 4, The Moon Overlooks the Waters The Moon Overlooks the Waters: "While donning the Ceremonial Garment created by Nereid's Ascension, Sangonomiya Kokomi's Normal Attack SPD is increased by 10%, and Normal Attacks that hit opponents will restore 0.8 Energy for her. This effect can occur once every 0.2s."
  • Constellation Level 6, Sango Isshin Sango Isshin: "While donning the Ceremonial Garment created by Nereid's Ascension, Sangonomiya Kokomi gains a 40% Hydro DMG Bonus for 4s when her Normal and Charged Attacks heal, or would heal, any party member with 80% or more HP." Healing a character at maximum HP counts for this constellation.
Damage Bonus Calculations
  • The Normal Attack "DMG Bonus" is applied differently from other Damage Bonuses. It is not added to other Damage Bonus percentages, but is rather added to the base damage (before other multipliers are applied). That is (without Crit), the outgoing Damage is:
  • The DMG Bonus at the end includes damage bonuses like Hydro DMG Bonus and Normal Attack DMG Bonuses.
  • The HP Ability Bonus is the DMG Bonus provided by the burst for the corresponding type of attack (Normal, Charged, Bake-Kurage).
  • With her second Passive Talent, the Ability Bonus becomes
