What is elemental mastery genshin impact?

Elemental mastery is a stat in Genshin Impact that increases the damage of elemental reactions. Elemental mastery is unique to each character and varies depending on their level and equipment. The higher the elemental mastery, the stronger the character's elemental reactions will be when they trigger with other elements. Elemental reactions occur when two or more different elements interact with each other, and the stronger the interaction, the higher the damage output. Some examples of elemental reactions include vaporize, melt, overload, and superconduct. Elemental mastery is an important stat for characters who are focused on dealing damage through elemental reactions, such as Xiangling, Diluc, and Fischl. It is also important for those who frequently switch between characters to trigger powerful elemental reactions to defeat enemies. It is recommended to focus on elemental mastery when building a team that relies heavily on elemental reactions.
