Diluc functions as a hard-hitting main DPS with off-field Pyro application through his Elemental Burst Dawn. Pair him with off-field Hydro or Cryo applicators like Xingqiu or Rosaria to trigger consistent vaporize or melt reactions. Equip him with a high-ATK claymore such as Wolf's Gravestone or Skyward Pride, and focus artifacts on Pyro damage and critical rate to maximize burst window damage.
