Normal Attack

In Nilou teams she triggers a large share of the Blooms herself, so full EM is worth it; she still heals enough to offset Bloom self-damage.

Teams

Recommended teams

Guide

How to play

How she works

Kurage's Oath (Skill) summons a stationary Bake-Kurage that deals Hydro DMG and heals the active character at regular intervals, based on her Max HP (20s cooldown).
Nereid's Ascension (Burst) deals Hydro DMG and dresses her in the Ceremonial Garment: her Normal Attacks, Charged Attacks and jellyfish deal more damage based on Max HP, and her attacks heal the whole party. It also grants interruption resistance and lets her walk on water. The effect ends if she leaves the field.
Tamakushi Casket (A1): using her Burst while the jellyfish is out refreshes its duration.
Song of Pearls (A4): in the Ceremonial Garment, 15% of her Healing Bonus is added to her Normal and Charged Attack bonus.
Flawless Strategy: +25% Healing Bonus, but -100% CRIT Rate. Never build CRIT on her.

Rotation

On-field: E, supports, then Q and chain N3 + dash (or N2 + dash). Charged Attacks apply more AoE Hydro but eat Stamina fast.
Off-field: E and swap out. Skip her Burst, or build enough ER to recast it and refresh the jellyfish through her A1.

The jellyfish does not follow enemies: place it where the fight will happen, and avoid it against mobile or repositioning bosses.

Strengths

Excellent healing, especially on-field, with no Stamina drain or timing to manage
Reliable Hydro application on and off the field
Easy to build: HP% and Energy Recharge, no CRIT at all
Fits many teams: Freeze, Bloom, Hyperbloom, Overvape, Electro-Charged

Weaknesses

Poor fit for Lunar reactions: with -100% CRIT Rate, her share of Lunar-Charged damage is weak
The stationary jellyfish misses enemies that move away
Low returns on constellations and signature weapon
20s Skill cooldown limits rotation flexibility

Notable dupes · Constellation

C1

Solid upgrade

The last hit of her Normal Attack combo fires a fish dealing 30% of her Max HP: a solid damage gain on-field.

C4

Solid upgrade

+10% Normal Attack SPD and Energy on hit during her Burst: lowers her ER needs.

C6

Solid upgrade

+40% Hydro DMG for 4s when her attacks heal a character at 80% HP or more.
