After meeting her Energy Recharge requirements, Iansan focuses almost exclusively on stacking ATK% to cap her buff. The cap is 690 ATK at talent Level 10 and 810 at talent Level 13, requiring Iansan to have 2556 ATK and 3000 ATK respectively to meet it when at above 42 Nightsoul points. She can continue to build ATK% after this to increase her buff even when below 42 Nightsoul points. If Favonius Lance is used, sufficient CRIT Rate should be run to consistently trigger its passive every rotation.
How much Energy Recharge Iansan needs to cast the Burst every rotation, by team and by weapon. Where a target is out of reach, the advice beside it says what to do instead.
| Team | With Favonius Lance | Other Weapons |
|---|---|---|
| Solo Electro | 200-210% | 220-280% |
| Double Electro | 140-150% | 180-200% |
| Reduction from C1 | -40% | -50% |
| Reduction per Extra Team Favonius Trigger | -20% | -20% |
| Reduction in Triple Natlan teams | -10% | -20% |
Calcs from the prydwen.gg guide, rephrased
#1
Burst
Max first
Iansan’s buff is tied to her Burst, and is thus the only talent worth maximizing when considering her poor personal damage.
EQ Combo
EQ
Iansan’s default combo at C2+, or at C0/C1 when paired with allies who can easily maintain her Nightsoul point generation and Iansan herself has sufficient ATK to reach her cap.
ECQ Combo
ECQ
Often used by C0/C1 Iansan to access the benefits of her first Ascension passive. Note that the Charged Attack can be accessed through the Normal Attack input.
ECQN1 Combo
ECQN1
If fighting an enemy with a permanent Hydro aura such as Tulpa and paired with a C6 Bennett, Iansan can trigger Scroll of the Hero of Cinder City for Pyro characters by fitting in a Normal Attack after her Burst.

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.

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.

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.
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.
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.
While in an area with Phlogiston Mechanics within Natlan, regain 10 Phlogiston when Phlogiston levels drop below 50%. This can occur once every 10s.

C1When Iansan is in combat and is in the Nightsoul's Blessing state, she will restore 15 Elemental Energy for every 6 Nightsoul points she consumes. This effect can trigger once every 18s.
C2When using the Elemental Burst The Three Principles of Power, Iansan will also gain the Precise Movement effect from her Ascension Talent "Enhanced Resistance Training" for 15s. Additionally, if Iansan is off-field while Precise Movement is active, she will also increase your current active character's ATK by 30%. You must first unlock the Ascension Talent "Enhanced Resistance Training" to access the above effect.
C3Increases the Level of Thunderbolt Rush by 3. Maximum upgrade level is 15.
C4When the Kinetic Energy Scale is present, Iansan will gain 2 stacks of Surging Force after your current active character (excluding herself) uses their Elemental Burst. The stacks last until the Scale leaves the field, and Surging Force can be gained once per Scale summoning. Whenever Iansan restores Nightsoul points via the Scale, she will consume 1 Surging Force stack and restore 4 additional Nightsoul points. Additionally, if her Nightsoul restoration from the Scale overflows, Iansan will gain 50% of the overflow the next time she restores Nightsoul points via the Scale.
C5Increases the Level of The Three Principles of Power by 3. Maximum upgrade level is 15.
C6The Kinetic Energy Scale's duration is increased by 3s. Additionally, when Iansan triggers Nightsoul point restoration, if there is any overflow, she will gain the Extreme Force effect, which increases the DMG dealt by your current active character by 25% for 3s.
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.
Names, descriptions and art from the game data. Pick an outfit on the stage to see it full size.
Iansan is a 4-star Electro character from Natlan who uses a polearm, released in version 5.5.
Iansan's abilities multiply ATK. That is read from the scaling rows on the Elemental Skill and Burst, not from the ability description, so it reflects what the game actually multiplies rather than what the text mentions.
Symphonist of Scents is the closest fit on the data: it is a 5-star polearm with CRIT DMG as its ascension stat, and its passive acts on ATK. Lithic Spear is the best 4-star alternative.
Thundering Fury. Its 2-piece bonus is: Electro DMG Bonus +15% Its 4-piece bonus is: Increases the DMG caused by Overloaded, Electro-Charged, Superconduct, and Hyperbloom by 40%, the DMG Bonus conferred by Aggravate by 20%, and the DMG caused by Lunar-Charged and Stellar-Conduct by 20%. When Quicken or the aforementioned Elemental Reactions are triggered, Elemental Skill CD is decreased by 1s. Can only occur once every 0.8s.
Taking one talent from level 1 to 10 costs 1,652,500 Mora and 38× Philosophies of Contention among other materials. The Materials tab lists every item per level.
Starting's Never Easy: When Iansan is in combat and is in the Nightsoul's Blessing state, she will restore 15 Elemental Energy for every 6 Nightsoul points she consumes. This effect can trigger once every 18s.
