Jean excels as a flexible support who heals off-field while enabling Viridescent Venerer for Anemo damage shred and group damage. Pair her with on-field carries that benefit from sustained healing and grouping, such as Fischl or Xingqiu for elemental reaction setups. Build her with Viridescent Venerer artifacts for elemental damage, prioritize Elemental Mastery and Energy Recharge, and equip a sword like Amenoma Kageuchi or Favonius Sword to maintain uptime on her healing burst.
