Yanfei is a four-star Genshin Impact character who wields a catalyst and harnesses the power of pyro. We first got to hear about her and Eula during the Genshin Impact update 1.5 special programme on April 16, 2021. If you want to keep up to date with all the latest news on Genshin Impact’s Yanfei, make sure you bookmark this page. We will fill you in on everything you need to know about her skills and ascension materials, and update this guide if there are any changes to her best weapons or artifacts. For those of you who need some extra primogems for the next Genshin Impact banner, take a look at our Genshin Impact codes list. For those of you looking for other strong characters, we have guides that include our recommended builds for Genshin Impact’s Diluc, Genshin Impact’s Xinyan, and Genshin Impact’s Bennett. What is the best Yanfei build? Yanfei truly excels when being used in a main DPS role. We recommend using her in a team with Genshin Impact’s Albedo to increase the damage of elemental reactions. Use her with Genshin Impact’s Ganyu to trigger melt with ease. Which weapon should you use? The Lost Prayer to the Sacred Winds is our catalyst of choice of Yanfei.
