Iansan GUIDE
Understand Iansan
Useful when…
- Boosting the active character’s ATK while the Kinetic Energy Scale is active.
- Healing the active character when Nightsoul point restoration occurs during Warming Up.
- Using faster movement and terrain-assisted leaps in Nightsoul’s Blessing.
How does her burst support the active character?
The Three Principles of Power deals AoE Electro damage, grants 15 Nightsoul points, and creates the Kinetic Energy Scale. The Scale follows the active character and boosts that character’s ATK. Below 42 Nightsoul points, the bonus depends on Iansan’s ATK and point total; at 42 or more, its conversion is 27% of Iansan’s ATK, capped at 330 points. While the Scale is active, it tracks the distance moved by the active character other than Iansan and restores Nightsoul points each second based on the previous second’s movement. The burst costs 70 Energy and its effect lasts 12 seconds. Iansan can remain off field without ending the state; the Scale disappears when her Nightsoul’s Blessing ends and one second after combat stops.
What do her skill and attacks add?
Thunderbolt Rush charges ahead for Electro damage, restores 54 Nightsoul points, and starts Iansan’s Nightsoul state. Using a Normal Attack within five seconds triggers one quick Swift Stormflight stomp without spending Stamina. In that state, Iansan moves faster; holding sprint enters Rushing Thunderbolt, which temporarily increases her speed further and allows terrain-assisted leaps. This mode can spend additional Nightsoul points to move over water or liquid Phlogiston, with immunity to damage from the latter. Her Normal Attack has three strikes. Her ordinary Charged Attack costs 25 Stamina; in Nightsoul’s Blessing, it becomes a Nightsoul-aligned AoE stomp that still costs Stamina.
How do movement and healing interact with support?
Movement by the active character can help the Scale restore Iansan’s Nightsoul points while it is active. When a nearby party member triggers a Nightsoul Burst, Iansan gains Warming Up for 10 seconds; restoring at least one Nightsoul point during that time heals the active character for 60% of Iansan’s ATK, once every 2.8 seconds. Hitting an opponent with Swift Stormflight grants Precise Movement for 15 seconds and increases Iansan’s ATK by 20%. During this effect, Scale restoration grants one extra Nightsoul point. If the active character consumes or restores Nightsoul points, the extra points Iansan gains on her next Scale restoration become four; this can occur once every 2.8 seconds.
What is a sensible investment focus?
For active-character support, the burst is relevant because its ATK conversion uses Iansan’s ATK; her healing passive also scales from ATK. The skill supplies Nightsoul points, enables mobility, and can set up the free follow-up stomp. Normal Attack investment is more relevant when you use those attacks for damage. Ascension and talent levels use separate resources, so the listed costs can help plan which part of her kit to develop.
What are the limitations?
The ATK calculation changes at 42 Nightsoul points, and the high-point conversion is capped at 330 points. Movement-based restoration depends on the active character’s movement during the previous second and requires the Scale to be active. The Scale ends when Iansan’s Nightsoul’s Blessing ends and vanishes shortly after combat stops. Her burst costs 70 Energy. Only specific movement, such as Rushing Thunderbolt over water or liquid Phlogiston, is stated to consume additional Nightsoul points; the one quick Swift Stormflight follow-up does not consume Stamina.
Limitations and tradeoffs
- Movement-based Nightsoul restoration requires an active Scale and depends on the active character’s movement.
- The burst costs 70 Energy, and the Scale can end when Nightsoul’s Blessing ends.
- Only specified movement options consume additional Nightsoul points; Swift Stormflight’s one quick follow-up is free of Stamina cost.
Common mistakes to avoid
- Expecting the high-point ATK calculation before reaching 42 Nightsoul points.
- Expecting movement-based point restoration while the Scale is inactive.
- Assuming the Scale persists after Iansan’s Nightsoul’s Blessing ends.
- Confusing the Stamina cost of Charged Attacks with the quick Swift Stormflight follow-up, which does not consume Stamina.

Thunderbolt Rush · Elemental skill
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.

The Three Principles of Power · Elemental burst
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.

Enhanced Resistance Training
After Swift Stormflight hits opponents, Iansan will gain the Precise Movement effect for 15s.
During this time, her ATK is increased by 20%, and whenever she regains Nightsoul points through the Kinetic Energy Scale in her Elemental Burst, The Three Principles of Power, she will gain 1 extra Nightsoul point. Additionally, when your current active party member consumes or restores Nightsoul points, the extra Nightsoul points Iansan gains the next time she restores Nightsoul points via the Scale will be increased to 4. This effect can occur once every 2.8s.
"Precise Movement" will expire when Iansan's Nightsoul's Blessing state ends.
Kinetic Energy Gradient Test
When a nearby party member triggers a Nightsoul Burst, Iansan will obtain the Warming Up effect for 10s.
During this time, when Iansan restores at least 1 Nightsoul point, she will heal your current active character for 60% of her ATK. This effect can be triggered once every 2.8s.
Night Realm's Gift: Hard Work and Drive
After Nightsoul points have been fully depleted and Iansan is on the field, she will switch to using Phlogiston to maintain her Nightsoul's Blessing.
While in an area with Phlogiston Mechanics within Natlan, Nightsoul Transmission: Iansan can be used. When the current active character is sprinting or in movement modes caused by certain Talents, or at a certain height in the air, switching to Iansan will trigger the following: Iansan enters the Nightsoul's Blessing state and obtains 25 Nightsoul points. Nightsoul Transmission can be triggered once every 10s by your own party.
While in an area with Phlogiston Mechanics within Natlan, Iansan will not take fall DMG when using terrain differences to make leaps.
Caloric Balancing Plan
While in an area with Phlogiston Mechanics within Natlan, regain 10 Phlogiston when Phlogiston levels drop below 50%. This can occur once every 10s.
