Qiqi's role is to provide consistent healing and Cryo application off-field through her Herald of Frost skill, making her ideal for freeze teams or extended exploration. Pair her with a Hydro applicator like Yelan or Xingqiu to enable freeze reactions, and equip her with a weapon that boosts ATK or energy regeneration to keep her burst available for the party-wide healing it provides. Prioritize HP and ATK scaling on artifacts to maximize her healing output and Cryo application frequency.
