Dehya functions as a self-sufficient main DPS who deals Pyro damage while also providing defensive utility through her shield mechanics, reducing the need for a dedicated healer. Pair her with off-field Hydro or Electro applicators (such as Xingqiu or Fischl) to enable vaporize or overload reactions. Equip a claymore with ATK or Pyro damage bonus, and prioritize ATK and Crit stats on artifacts—sets like Crimson Witch or Wanderer's Troupe complement her on-field playstyle.
