Best Artifacts for Iansan

Scroll of the Hero of Cinder City

Scroll of the Hero of Cinder City

2-Piece Set: When a nearby party member triggers a Nightsoul Burst, the equipping character regenerates 6 Elemental Energy.

4-Piece Set: After the equipping character triggers a reaction related to their Elemental Type, all nearby party members gain a 12% Elemental DMG Bonus for the Elemental Types involved in the elemental reaction for 15s. If the equipping character is in the Nightsoul's Blessing state when triggering this effect, all nearby party members gain an additional 28% Elemental DMG Bonus for the Elemental Types involved in the elemental reaction for 20s. The equipping character can trigger this effect while off-field, and the DMG bonus from Artifact Sets with the same name do not stack.

Noblesse Oblige

Noblesse Oblige

2-Piece Set: Elemental Burst DMG +20%

4-Piece Set: Using an Elemental Burst increases all party members' ATK by 20% for 12s. This effect cannot stack.

Iansan's Stat Priority

: ATK % / Energy Recharge

: ATK %

: ATK % / CRIT Rate (With Favonius)

Substats: Energy Recharge (to requirements) > ATK % > CRIT Rate (With Favonius)

Iansan's stat priority revolves entirely around meeting her Energy Recharge requirements to cast her Burst, and then stacking as much ATK % as possible to maximize her buffs and healing. If you are using Favonius Lance, ensure you have enough CRIT Rate to trigger its passive.

Energy Recharge Breakpoints

Iansan's Energy Recharge requirements depend heavily on how many Electro characters are in the party, as well as if Iansan has her Constellation 1 unlocked. If using an ER weapon such as Engulfing Lightning or Favonius Lance, her artifact ER requirements will be much easier to reach.

Recommended Stats for Iansan

Build recommendations assume a support-focused Iansan. Exact ATK values will depend greatly on your equipped weapon's Base ATK.

Iansan's Talent Priority

When building Iansan strictly as a support buffer and healer, her Elemental Burst, The Three Principles of Power, is the only talent that truly needs investment. You can safely leave her Normal Attacks un-leveled.

How to Play Iansan

Iansan is a very flexible buffer and excellent holder for the Scroll of the Hero of Cinder City artifact set. She is best placed in teams with ATK-scaling DPS characters. Because her Kinetic Energy Scale from her Burst restores Nightsoul points based on the active character's movement distance, she pairs best with characters that feature high mobility in their kits.

Characters from Natlan such as Mavuika, Varesa, and Kinich inherently have high mobility and work exceptionally well with her. Plunge-focused DPS characters like Xiao or any character supported by Xianyun also synergize perfectly, as vertical mobility (jumping and plunging) contributes significantly towards maintaining Iansan's ATK buff.

Iansan's Best Constellations

Iansan has some amazing constellations that greatly enhance her supportive playstyle, making her even easier to build and stronger for the team.

Starting's Never Easy (C1) is a massive quality-of-life improvement as it significantly reduces her Energy Recharge requirements, allowing you to focus more artifact rolls purely into ATK %.

Laziness is the Enemy! (C2) provides a powerful additional 30% ATK buff to your active character while Iansan is off-field, solidifying her role as a premier attack buffer.

Teachings of the Collective of Plenty (C6) increases the duration of her Kinetic Energy Scale by 3 seconds and provides a direct 25% DMG increase to the active character, taking her overall team buffing potential to the next level.
