Yes — her entire reaction kit works at C0. C2 gives a massive quality-of-life buff, but isn’t required.
Best F2P team for Iansan?
Iansan + Fischl + Barbara + Dendro MC = consistent Hyperbloom
What about physical DPS builds?
Not recommended. Her EM and elemental focus make physical builds nonviable.

Is Iansan Worth Pulling in Genshin Impact?

Iansan thrives in reaction-heavy teams where Dendro meets Electro or Hydro. Her EM-scaling skill, fast cooldowns, and synergy with Nahida, Fischl, and Raiden make her a top-tier sub-DPS for Hyperbloom players. She’s easy to build, fun to use, and fits into both casual and Abyss-tier strategies.

Whether you’re chasing the leaderboard or just love watching seeds pop, Iansan is one of the most satisfying Dendro units to play in Version 5.5.
