I recently got Yelan in Genshin Impact. How do I best build her? What artefacts, weapons and team compositions do you suggest?
Congratulations on getting Yelan! She is a 5-star Hydro Bow character who can be a great Sub-DPS or Support for your team. Some of the best builds for Yelan are:

- Sub-DPS: Aqua Simulacra or Elegy for the End as weapon, Emblem of Severed Fate x4 as artifacts, with main stats of HP% or Energy Recharge on Sands, Hydro DMG Bonus on Goblet, and CRIT Rate or CRIT DMG on Circlet. This build focuses on maximizing her Elemental Burst DMG and Energy Recharge.
- Support: Aqua Simulacra or Elegy for the End as weapon, Noblesse Oblige x4 as artifacts, with main stats of Energy Recharge on Sands, Hydro DMG Bonus on Goblet, and CRIT Rate, CRIT DMG or HP% on Circlet. This build aims to improve the overall damage of the team with the Noblesse Oblige 4pc. effect.

Some of the best team compositions for Yelan are:

- Hu Tao Vaporize: Hu Tao (Main DPS), Yelan (Sub-DPS), Alhaitham (Support), Quickbloom (Healer). This team can deal massive Vaporize damage with Hu Tao and Yelan’s Hydro application.
- Nilou Hyperbloom: Nilou (Main DPS), Yelan (Sub-DPS), Dehya (Support), Cyno (Support). This team can create a lot of Elemental Reactions with Nilou’s Electro skills and Yelan’s Hydro skills.

I hope this helps you build your Yelan and enjoy the game! 😊
