Overview
Iansan supplies an ATK buff through a following Kinetic Energy Scale. The active character’s movement helps sustain it, so mobile and stationary damage windows receive different practical support.
Role
ATK-based moving-character support
Playstyle
Enable Precise Movement, deploy the Scale and let the supported active character move enough to replenish Nightsoul.
Why It Works
Below the native Nightsoul threshold the buff depends on both resource and ATK; above it the stronger form uses ATK.
Watch For
A stationary damage window may sustain the Scale differently from a mobile one; do not promise permanent maximum support.
Playstyle
Combat Flow
Use the Skill and quick Swift Stormflight follow-up to enable Precise Movement. Cast the Burst and transfer to the attacker, whose movement helps retain the stronger Ardent Support state.
Key Notes
Warming Up can supply conditional ATK-scaling healing after a Nightsoul Burst.
Movement by the active character replenishes her Nightsoul points.
Swift Stormflight enables Precise Movement; C2 also enables it on Burst.
Her minor healing is not sufficient by itself for Furina’s repeated team drain.

Elemental Skill
Thunderbolt Rush
Iansan charges forward a certain distance, dealing Nightsoul-aligned Electro DMG to all opponents in her path.
After this Skill is used, Iansan will regain 54 Nightsoul points and enter the Nightsoul's Blessing state. Within 5s after this is done, using a Normal Attack will trigger 1 quick Swift Stormflight stomp from Iansan that will not consume Stamina.
Nightsoul's Blessing: Iansan
Continuously consumes Nightsoul points. If she runs out, or uses this Skill again, her Nightsoul's Blessing state will end. It has the following properties:
· Increases Iansan's Movement SPD.
· Holding sprint will switch Iansan to Rushing Thunderbolt mode, greatly increasing her Movement SPD temporarily. In this mode, Iansan can make flying leaps using terrain, or consume additional Nightsoul points to move on water or liquid Phlogiston while being immune to DMG from the latter.

Elemental Burst
The Three Principles of Power
Iansan's stomping foot shatters the very earth with "Power," dealing Nightsoul-aligned AoE Electro DMG. She then whips out her "Limited-Edition Kinetic Energy Scale (For Workouts)."
When this Skill is used, Iansan will gain 15 Nightsoul points and enter the Nightsoul's Blessing state.
When the Kinetic Energy Scale leaves the field, Iansan's Nightsoul's Blessing state will end.
Kinetic Energy Scale
The Kinetic Energy Scale will follow the character around, boosting the ATK of your current active party member in different ways based on Iansan's Nightsoul points.
· If Iansan has less than 42 Nightsoul points, the ATK bonus will be based on her Nightsoul points and ATK.
· If Iansan has at least 42 Nightsoul points, the Kinetic Energy Scale will switch to the "Ardent Support!" state, in which the ATK bonus will be stronger and based on her ATK alone.
Additionally, the Scale will log the distance your current active character (excluding Iansan) has moved so long as it is active, restoring Nightsoul points to Iansan every second based on the distance moved in the previous second.
The Scale will disappear once her Nightsoul's Blessing state ends. It will also disappear after 1 second when you are not in a state of combat. While it is active, Iansan's Nightsoul's Blessing state will not end even if she is not on the field.
