Bennett has been one of the best supports in Genshin Impact since the game’s release, thanks to his powerful ATK buff, healing, and Pyro application. Now, with Iansan’s arrival, many players are wondering if she can replace him or even outperform him in certain teams.
While both characters are supports, their mechanics and playstyles are quite different. This guide will compare their strengths, weaknesses, and ideal use cases to help you decide which character suits your team better.
An Overview of Bennett and Iansan in Genshin Impact
Bennett – The Unreplaceable 4-star Pyro support
Bennett is one of the best support characters in Genshin Impact, known for his strong healing, massive ATK buff, and Pyro application. His Elemental Burst, Fantastic Voyage, creates a field that heals allies while providing an ATK boost based on his Base ATK.
This makes him highly versatile, fitting into almost any team that benefits from an ATK increase. With his fast Energy regeneration and low-cost Burst, Bennett remains one of the most consistent and reliable supports in the game.
Iansan – A new Movement-Based Electro Support
Iansan introduces a unique movement-dependent buffing mechanic through her Nightsoul system. Instead of a stationary ATK boost like Bennett, she provides an ATK bonus based on the movement of the active character, making her an excellent choice for mobile DPS units.
She also generates Energy for herself and the team, especially at higher constellations. While she lacks strong healing, her buffs work for any element, making her a flexible choice for multi-element teams. As a Natlan unit, Iansan can use the Cinder City set to give 40% DMG bonus.
Benett vs Iansan: Buffing & Support Capabilities
Bennett
- ✅ Instant ATK Buff: Provides an immediate ATK boost inside his Elemental Burst field, making it highly effective for most DPS characters.
- ✅ Healing Scales with HP: His Burst also heals allies based on Bennett’s Max HP, making him both a buffer and a healer.
- ✅ Consistent & Easy to Use: The buff is reliable and does not require any specific movement or mechanics—just stay inside the circle.
- ❌ Burst is Stationary: His ATK buff is limited to a fixed area, meaning characters who move frequently may struggle to stay within it.
Iansan
- ❌ Buff Uptime Depends on Movement: To maximize her buff, characters must be constantly moving, which may not work for all DPS units.
- ✅ Scroll of the Hero of Cinder City Synergy: When using this artifact set, she can grant up to 40% Elemental DMG Bonus to her team, significantly boosting her support potential.
- ❌ Needs Energy to Maintain Buffs Effectively: Her Nightsoul mechanic requires proper Energy Recharge management to keep her buffs active.
Bennett vs Iansan: Energy Management & Generation
Bennett
- ✅ Reliable Energy Generation: His Elemental Skill generates a steady flow of Pyro particles, making it easy to recharge his Burst.
- ✅ Low Energy Cost: His Elemental Burst only costs 60 Energy, allowing him to use it frequently without needing excessive Energy Recharge.
- ❌ Self-Sufficient but Lacks Team Energy Support: While Bennett generates energy for himself efficiently, he does not provide additional Energy Recharge to teammates.
Iansan
- ✅ Better Energy Support at C1 & C4: Her C1 restores 15 Energy every 18 seconds, helping her Burst uptime. At C4, she restores additional Nightsoul points, improving her overall energy efficiency.
- ✅ She can use Scroll of the Hero of Cinder City: If Iansan equips this artifact set, she can provide an additional 40% DMG Bonus to the team, further boosting overall damage output.
- ❌ Higher Energy Needs: Without constellations or proper Energy Recharge investment, she may struggle to maintain consistent Burst uptime.
Bennett vs Iansan: Which Character Should You Use?
Who Benefits More from Bennett’s Buffs?
Bennett’s instant ATK buff is great for most DPS characters, especially those who scale primarily with ATK, like Hu Tao, Xiao, Ayaka, and Eula. His healing and Pyro application make him an excellent choice for Vaporize and Melt teams. However, his Burst’s fixed circle limits movement, which can be problematic for mobile DPS units like Clorinde, Neuvillette, and Itto.
Who Benefits More from Iansan’s Buffs?
Iansan also provides an ATK buff, but unlike Bennett, her buff depends on movement instead of being tied to a stationary circle. This makes her a better fit for characters who move frequently, such as Clorinde, Itto, Wanderer, Varesa, and Mavuika. Additionally, if she equips Scroll of the Hero of Cinder City, she can further boost the team’s Elemental DMG while also restoring Energy.
Which Constellations Make a Difference?
- Bennett C1: Removes HP restrictions on his Burst’s ATK buff, making it always apply.
- Bennett C6: Grants Pyro infusion, which can be great or disruptive, depending on the team.
- Iansan C1: Improves Energy Recharge, allowing for more frequent Bursts.
- Iansan C2: Grants an additional 30% ATK boost, making her an even stronger buffer.
- Iansan C6: Extends her buff duration by 3 seconds and grants an extra DMG boost to the active character if she overfills Nightsoul points.
Overall, Bennett is easier to use, while Iansan requires movement to maintain her buffs but offers flexibility. If you have a mobile DPS, Iansan may be the better choice, but Bennett remains the safer, more consistent option.
