You should farm Citlali’s materials in Genshin Impact to ensure you adequately Ascend her and level up her Talents before you start working on her build, thus optimizing the character as a support unit for your team comps. Citlali is a Cryo character introduced with Version 5.3, the same patch that brought forth Mavuika as a playable character in HoYoverse’s action RPG. While Mavuika is a damage dealer, split between operating as a DPS and a sub-DPS, Citlali’s kit in Genshin Impact sees her working as a support capable of providing shields for her party members.
