In Genshin Impact, Bennett and Iansan stand as two versatile 4-star supports, each offering unique strengths in healing, ATK buffs, and team synergy. This guide breaks down their key differences in roles, skills, and team compatibility to help you decide which suits your playstyle best.

▍1. Role and Functionality 

 Bennett: A 4star Pyro support in Genshin Impact, renowned for his versatility. His Elemental Burst (Wonderful Wishes) provides both healing and ATK buffs, making him a staple in many teams. However, his healing and buffs are tied to his base ATK, not his total ATK, and require allies to stay within his burst area . 

 Iansan: A 4star Electro support introduced in Genshin Impact 5.5. Her kit focuses on ATK buffs and minor healing. Unlike Bennett, her buffs follow the active character regardless of distance, making her ideal for mobile teams. Her Elemental Burst (Kinetic Mark) scales with her total ATK, allowing flexibility in artifact choices . 

▍2. Skill Mechanics 

 Bennett: 

   Elemental Burst: Grants a Pyro AoE that heals and increases ATK for allies inside it. The ATK buff is conditional (ally HP <70% for healing, HP >70% for ATK). 

   Drawback: Requires allies to stay within the burst’s range, limiting mobility . 

 Iansan: 

   Elemental Burst: Summons a floating marker that boosts the active character’s ATK based on Iansan’s total ATK. The buff persists even if the character moves, and the marker can be recharged via the active character’s movement . 

   Elemental Skill: Enhances normal attacks into AoE Electro damage and restores "Night Soul" energy for her burst . 

▍3. Team Synergy 

 Bennett: 

   Best With: Teams that benefit from healing and stationary damage dealers (e.g., Xiangling, Diluc). 

   Limitations: Less effective with highly mobile characters like Yoimiya or Wanderer . 

 Iansan: 

   Best With: Teams with mobile DPS units (e.g., Klee, Ayaka) or those requiring offfield support. Her buffs also synergize well with Electro reactions like Aggravate or Hyperbloom . 

   Unique Edge: Can pair with Bennett in the same team to stack ATK buffs, offering both healing and mobility . 

▍4. Artifacts and Weapons 

 Bennett: 

   Artifacts: Emblem of Severed Fate, Instructor, or Noblesse Oblige. 

   Weapons: Festering Desire, Aquila Favonia (for base ATK) . 

 Iansan: 

   Artifacts: Emblem of Severed Fate, Gladiator’s Finale, or the new Ashen Knight’s Oath set (which boosts ATK and Electro damage) . 

   Weapons: The Flute, Skyward Blade, or any ATK% weapon . 

▍5. Advantages and Disadvantages 

▍6. Conclusion 

 Bennett remains irreplaceable for teams needing reliable healing and ATK buffs, especially in stationary setups.

 Iansan shines in mobile or Electrocentric teams, offering unmatched flexibility with her followup buffs. She complements Bennett well in dualsupport comps. 

For players prioritizing healing and simplicity, Bennett is the goto. Those seeking mobility and Electro synergy should invest in Iansan. Both are toptier supports, but their strengths lie in different playstyles .
