Shenhe's team composition will mainly consist of Cryo units, as this Genshin Impact character is specifically designed to support this Element. With her Elemental Skill, Shenhe can grant damage bonuses to the team according to her Attack. So the key build for Shenhe in Genshin Impact is to stack as much Attack as possible. However, it's important to note that this damage buff is only triggered if players deal Cryo damage.
