Fischl excels at applying Electro off-field through Oz, making her a cornerstone for Electro reaction teams like aggravate or overload comps. Pair her with a main DPS that can trigger reactions frequently—such as an Anemo, Cryo, or Pyro on-field carry—and prioritize Electro damage and crit substats on artifacts like Thundering Fury or Gilded Dreams. Her Constellation 6 dramatically boosts her personal damage, but even at lower constellations her off-field support is valuable.
