Overview
Aino leaves a Hydro-firing cooler for another character to drive reactions. EM also contributes to her Burst damage, but enemies must stay within the cooler’s fixed area.
Role
Off-field Hydro zone / EM-linked Burst damage
Playstyle
Use Musecatcher briefly, deploy the cooler and switch to the reaction driver.
Why It Works
EM adds to Burst damage through Structured Power Booster.
Watch For
Reaction ownership must still be established; EM-linked Burst damage does not prove every team reaction belongs to Aino.
Playstyle
Combat Flow
Place the Burst zone around the fight after the Skill action. Choose the Moonsign level deliberately; Ascendant Gleam increases firing frequency and area without changing the zone into a following effect.
Key Notes
The cooler supplies persistent Hydro while Aino can remain off-field.
Use a few Normal Attacks if Favonius needs another chance to trigger.
Her Hydro application is insufficient alone for demanding Hyperbloom teams.

C2The Principle of Transference in Gear Differentials
If Aino is off-field while the Focused Hydronic Cooling Zone of her Elemental Burst Precision Hydronic Cooler is active, when your active party member hits a nearby opponent with an attack, the Cool Your Jets Ducky will fire an additional water ball at that opponent, dealing AoE Hydro DMG equal to 25% of Aino's ATK and 100% of her Elemental Mastery. This DMG is considered Elemental Burst DMG. This effect can be triggered once every 5s.
