Hu Tao scales off of her maximum HP. Her elemental skill (E) enables her to gain a high number of attack damage based on her maximum HP, and her elemental burst also scales with the amount of HP she has. Therefore, players should focus on increasing her HP by equipping her with HP artifacts on her sands. Other important stats to focus on include critical hit rate, elemental mastery, Pyro, Normal, and/or Charged Attack DMG%, and CRIT Rate/DMG. It is also recommended to equip her with the Staff of Homa or White Tassel weapon, which increases health and provides an attack bonus based on a percentage of the wielders max health. Additionally, players can equip Xingqiu or Yelan as her final party member to gain the Wet effect and maximize her damage with powerful Vaporized Charged Attacks.
