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.

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.

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.
