Charlotte applies Cryo consistently off-field and pairs well with Freeze or Cryo-reaction teams that benefit from sustained element application. Pair with a Hydro on-field carry like Neuvillette or Yelan for Freeze or Cryo-Hydro reactions, or use in Cryo-focused teams needing reliable off-field coverage. Catalyst users benefit from Noblesse Oblige or Emblem of Severed Fate to boost team damage, though energy requirements and personal damage thresholds should guide weapon and mainstat choices.
