Sara provides Electro off-field damage and a valuable ATK buff to the active character through her skill and burst. She works well in Electro teams alongside a main DPS like Fischl or Raiden Shogun, or as a support in physical-focused teams that need electro application. Prioritize ATK% and Crit Rate in artifacts to maximize her personal damage and buff potency, and consider The Widsith or Favonius Warbow to support energy needs and team damage.
