Xinyan functions as an on-field Physical damage dealer buffed by her own shield and Pyro application. She pairs well with off-field Cryo or Electro applicators like Fischl or Rosaria to trigger Superconduct for Physical resistance shred. Build her with a Physical Damage Bonus claymore like Snow-Tombed Starsilver or the Serpent Spine, and prioritize DEF for shield strength while balancing ATK for her Physical scaling.
