Genshin Impact 2.7 is still around the corner and players have already seen the game teasing Yelan's appearance with the latest quest cutscenes. Yelan is the latest 5-star character to appear on the feature banner for the first time. She is an upcoming Hydro-bow user with a lot of potential to become the next best Hydro support in the game.All her Elemental skills and burst damage specialize in the role of Sub-DPS which is very similar to Xingiqu. Yelan fans should start farming ascension and talent materials early as all her required materials are available in the current version of the game.EiLatte@SimpForEiMiko/Genshin leak/YELAN’S BURST ANIMATION SO BADASS OMGCr: Ubatcha44153/Genshin leak/YELAN’S BURST ANIMATION SO BADASS OMGCr: Ubatcha https://t.co/vuAtuU1slGHere is a quick guide for players to learn everything about Yelan's ascension materials, talent books, and how many primogems they will need to summon her in Genshin Impact.Genshin Impact: Farming guide for Yelan's Ascension materials and Talent booksYelan is from Liyue, so it makes sense that all the materials required to fully ascend her to level 90 are available in the region.

The amount of Primogems that one needs to save varies on two factors - their luck and whether they have a guarantee on their 5-star summons.For example, if a player is summoning Yelan from her banner but ends up getting Diluc, then they get a guarantee that if they pull for another 5-star, they will acquire Yelan.According to the pity system of Genshin Impact, players need to make 90 wishes on the feature banners to summon a 5-star. Hence, they will need 14,400 primogems to summon a 5-star.In case of guarantee, players will only need 14,400 primogems or less depending on the pity count. They can count their pity on the History page, which can be found on the Event wish page. However, for those who do not have such guarantee, they will need around 28,800 primogems to make sure they can summon a Yelan for their team.
