Genshin Impact Iansan Buff Explained & Best Teams to Use Guide!

Iansan is making waves as a versatile support and attack buff provider in Genshin Impact. Known for her unique mechanic that rewards movement through “night soul points,” she offers substantial attack boosts for DPS characters. This guide explains her core mechanics, how her constellations enhance her performance, and which teammates work best with her at both C0 and C6.

Understanding Iansan’s Buffs Mechanics

Iansan’s effectiveness revolves around accumulating “night soul points” by moving—both horizontally and vertically. Each meter traveled contributes roughly two-thirds of a point. The key is to maintain her above 42 out of a maximum 54 night soul points for optimal performance. When she’s above that threshold, her attack buff scales at 27% of her attack stat for the active character. If she falls below 42 points, the buff is significantly lower, around 21% or less.

Her elemental skill, charged attack kick, and burst form the backbone of her rotation. After using her burst, she relies on maintaining enough night soul points to keep her buff strong. A visual indicator helps track this: a rooting icon means she’s above the target, while a skull/mask signals that she’s disappointed with the current “fitness” level of your character’s movement.

Iansan’s Constellation Enhancements

Iansan’s potential increases markedly with her constellations:

• Constellation 2: Adds a flat 30% attack buff.

• Constellation 4: Improves night soul point regeneration by granting an extra 50% of any overflow points during burst restoration.

• Constellation 5: Enhances her elemental burst by adding three extra levels, pushing her maximum buff from around 690 attack to 810 attack.

• Constellation 6: Provides a 25% bonus damage for three seconds if her night soul points are overfilled, and also extends her burst duration by three seconds. This extra time can be crucial for adjusting rotations and ensuring the buff is passed effectively to the team.

These upgrades not only boost her personal performance but also make her an even more formidable alternative to traditional attack buffers like Bennett.

Best Optimal Team Compositions for Iansan Buff & Why

The effectiveness of Iansan’s buff is highly dependent on the movement and skill usage of the DPS characters on the field. Here’s a breakdown of key team synergies tested at both constellation zero and constellation six:

1. Plunge and Movement-Based DPS:

Characters such as Varesa and Mavuika work exceptionally well with Iansan. Their attack animations—especially plunge attacks and dashes—generate enough movement to easily maintain and even overfill night soul points. Varesa, for instance, can see her damage increased by up to 74% with Iansan at C6 when she consistently exceeds the 42-point threshold.

2. Characters with Agile Rotations:

DPS like Kinich and Gaming, who incorporate plenty of dashes and dynamic movement, maintain Iansan’s buff reliably. Their fluid combat style ensures that night soul points remain at the optimum level throughout fights.

3. Snapshot Burst DPS:

For characters such as Ayaka and other burst-focused DPS, the timing of their elemental bursts is key. Even if they don’t move as much overall, their damage is front-loaded—meaning they can benefit greatly from Iansan’s burst buff if timed correctly.

4. Challenges with Stationary DPS:

Some characters, like Clorinde or Raiden Shogun, have issues with sustaining movement. Their relatively static combat style makes it hard to generate the necessary night soul points, which may reduce the overall effectiveness of Iansan’s buff. In these cases, team adjustments or alternative characters might be preferable.

5. Special Considerations:

Characters such as Arleccino may face team-building challenges due to synergy issues, while others like Navia require specific setups (for example, a plunge team) to fully leverage Iansan’s benefits.

Iansan stands out as a potent attack buffer in Genshin Impact, rewarding dynamic play and active combat movement. When paired with agile, attack-scaling DPS characters, her buff can dramatically enhance overall damage output—even rivaling the popular Bennett setups. By understanding her mechanics, optimizing team compositions, and fine-tuning rotations, you can harness the full potential of Iansan for your account.

Take this guide as a starting point to experiment with various team configurations and find the synergy that best suits your playstyle. With careful planning and some in-game testing, you’ll be well on your way to maximizing damage and dominating your battles with Iansan at the helm. Enjoy the journey and may your teams always be in perfect motion!
