Iansan's buff is based on 3 factors:

Iansan's Total ATK
54 Nightsoul Points
Kinetic Energy Scale

Iansan can hold a max of 54 Nightsoul Points, and her buff decreases in value when she's below 42 Nightsoul Points. Consistent movement is needed to maintain good buff uptime.
Iansan's C4 allows her to frontload Nightsoul Points if it had ever overflowed previously.

Iansan buffs her teammates through her Elemental Burst, as well as provide some additional healing for the active character through one of her passives. Characters with movement-based abilities will greatly contribute to Iansan's buff as Iansan's own movement cannot contribute to it. Movement is needed to help Iansan maintain a high number of Nightsoul Points, and the active character gaining and consuming Nightsoul Points can also contribute. Movement is defined as anything that moves the active character for any amount of distance, whether vertical or horizontal. This includes things such as attacks, skill and burst animations, jumping, etc. Almost any kind of movement will contribute, as long as it's not Iansan's own. This also extends to the gain and consumption of Nightsoul Points.
Iansan's C1 gives her 15 Energy upon consuming 6 Nightsoul Points as long as she's in combat and in Nightsoul Blessing state, effectively changing her burst cost from 70 to 55. This has a cooldown of 18 seconds.
Regarding Weapon Choices: It is important to note that at C0, using non-ER weapons in teams where Iansan is the only Electro may be unrealistic due to how high her ER needs can become. In addition, in teams where movement is scarce, ATK weapons gain greater value.

Favonius Lance: With this weapon, you want to build some Crit Rate to help proc the passive.
Symphonist of Scents: Keep in mind that the fewer Natlan characters you have on your team, the lower the buff’s uptime will be with near perfect uptime usually only achievable when using three or more Natlan characters.

Best Iansan Teams

Iansan Skills

Weighted Spike

Normal Attack
Performs up to 3 consecutive spear strikes.

Charged Attack
Consumes a certain amount of Stamina to lunge forward, dealing damage to opponents along the way.

Plunging Attack
Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact.

Nightsoul State: Swift Stormflight
While in the Nightsoul's Blessing state: Iansan's Charged Attack will be transformed into the formidable Swift Stormflight, consuming a certain amount of Stamina to stomp fiercely down, dealing Nightsoul-aligned AoE Electro DMG.

Thunderbolt Rush

"Faster, stronger! That's what all that hard work is for!"

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

"Power is not about natural talent. Power stems from unceasing practice. Power must be exercised correctly."

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.

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.

When a nearby party member triggers a Nightsoul Burst, Iansan will obtain the Warming Up effect for 10s.

Night Realm's Gift: Hard Work and Drive

Passive

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.

Outfits

Warrior's Bonegarb

Default

Iansan's outfit. Adorned with a patterned skull that has become something of an icon for Iansan. Her trainees initially believed that their coach wore it to commemorate the tragic passing of her Tatankasaur, until they realized it was still alive and well.
