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

The Three Principles of Power
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.
"Power is not about natural talent. Power stems from unceasing practice. Power must be exercised correctly."
Passive Talents

Enhanced Resistance Training
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
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
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
DefaultIansan'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.
When the people of Natlan think about the Collective of Plenty, the first thing that springs to mind is the tribe's culture of fitness — followed shortly by mental images of towering, muscular, chiseled physiques... Many first-time visitors to the Collective of Plenty, therefore, are surprised to learn that the current leading light of the tribe's fitness scene is about as far away from those mental images as it's possible to be. As tall — or short — as a child, the young lady in question is positively scrawny when compared with most of her peers. This young lady — whose unimposing frame gives the impression that a strong gust of wind might well blow her away — is the head coach of the fitness club at the Collective of Plenty: Coach Iansan. At first, many visitors had assumed that the tribe were merely playing a trick on outsiders. But in due course, there was ample opportunity for newcomers to witness Coach Iansan directing training sessions — and the aftermath, with her students collapsed exhausted on the floor while she herself had hardly broken a sweat. Eventually, with the eyes of all Natlan watching, Iansan proved her prowess on the greatest stage, setting an all-time victory record in the Pilgrimage of the Return of the Sacred Flame. And now, Iansan is widely recognized as the gold standard for trainers in Natlan. She has even set up her own special training camp to teach the techniques required to attain victory in the Pilgrimage of the Return of the Sacred Flame. Folk are shocked by Iansan's strength and curious as to its source. There are rumors that she has an unusual lineage, one which bestows her with extraordinary strength, but also uncommon shortness. Whenever outsiders to the tribe attempt to confirm these rumors with the Collective of Plenty, however, their questions are met by little more than icy stares and an equally frosty answer: "Hmph, she trains hard." Having met their perfunctory burden of manners, the people of the Collective of Plenty will then return to working out, leaving behind befuddled outsiders who are unsure exactly what they did to cause offense. And so new rumors begin to spread, ones that claim Iansan's power is derived from a secret tribal weapon belonging to the Collective of Plenty — a weapon that they are forbidden from talking to outsiders about. Whenever such rumors begin to do the rounds, Iansan is quick to seek out the curious questioners. "You too can be as strong as me. Join my training academy and I guarantee you results!" Once their shock has faded, most people decline the offer. Perhaps they don't believe that Coach Iansan can really guarantee success, or perhaps they've already heard stories of just how grueling her training really is. The rumors surrounding Iansan continue to swirl and spread. On the rare occasions when she isn't training and has the time to pay them heed, Iansan can only sigh and shake her head. "I keep telling them it's down to the training... Why doesn't anybody listen?"
Hi there, I'm Iansan from the Collective of Plenty, and I'm the most well-known fitness coach in my tribe. You look like you're in pretty good shape... do you work out, too?
