Shared Team Members

With Lan Yan

Fischl provides rapid off-field Electro application through Oz, which allows Lan Yan to trigger frequent Electro-Charged reactions and Swirls. This constant reaction chain helps maximize Lan Yan's role as a driver for elemental damage.

With Sayu

Fischl's Oz provides a reliable Electro source for Sayu to Swirl during her Fuuin Dash. This enables Sayu to Shred Electro RES with the Viridescent Venerer set while also triggering her own EM-scaling heals.
