Talent Kurage's Oath.pngKurage's OathElemental Skill
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.

  • Particle generation: Bake-Kurage has ~2/3 chance to generate an elemental particle when it hits at least 1 enemy, except at the last damage tick.
    • Generate on average 2/3 × 6 = 4 elemental particles if all ticks hit an enemy.
  • Interval: 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
  • Sangonomiya Kokomi's first Passive Talent, Tamanooya's Casket, refreshes her own Bake-Kurage's duration if it is already on the field at the time Nereid's Ascension is activated.

Talent Nereid's Ascension.pngNereid's AscensionElemental Burst
The might of Watatsumi descends, 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 move on the water's surface.

These effects will be cleared once Sangonomiya Kokomi leaves the field.

  • When standing on Electro Water during the duration of her burst, Kokomi will still take damage.
  • With Sangonomiya Kokomi's second Passive Talent, Song of Pearls, her Normal and Charged Attack DMG Bonus gained based on her Max HP will receive a further increase based on 15% of her Healing Bonus when donning the Ceremonial Garment.
  • Additional effects from Constellations:
    • Constellation 3 (The Moon, A Ship O'er the Seas): Increases Nereid's Ascension's current level by 3 and raises the talent maximum level to 15.
    • Constellation 4 (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.
    • Constellation 6 (Sango Isshin): While donning the Ceremonial Garment created by Nereid's Ascension, Sangonomiya Kokomi gains a 40% Hydro DMG Bonus for 4s after her Normal and Charged Attacks heal a character with 80% or more HP.
  • 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 other damage bonuses like Hydro Damage Bonus.
  • 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

Example calculation

At talent level 6 for both the normal attack and burst, with the 2nd passive, 30000 HP, 1000 attack, 40% Healing Bonus, only 40% Hydro Damage Bonus, no crit, and no reactions, the damage done to a Mitachurl by the first normal attack (scaling 95.73%) without the burst active is roughly: 603.099.

When the burst is activated, at level 6 the burst normal attack bonus will be 6.78%, and she will gain the following additional outgoing damage

After applying the DEF and RES modifiers for a Mitachurl, the additional incoming damage is 2415.42.

So the total damage of the first NA hit with the burst activated is the sum
