Candace is a 4-star Hydro Support who specializes in providing off-field Hydro application with her HP-scaling Burst, infusing melee allies' Normal Attacks with Hydro and providing defensive utility with her Skill.
It is worth noting that Candace will never be the strongest option for your teams. At the cost of having different kinds of utility in one kit, she will never be the best at them. Her damage contribution is surpassed by offensive Hydro supports like Xingqiu, and her defensive capabilities are outclassed by other Hydro healers.
Because of this, it is recommended to focus on Candace's strength as a consistent Hydro applier by getting as much Energy Recharge as possible, helping her maintain consistent uptime. Her weapon and artifact rankings therefore focus on Particle/Energy generation and Recharge.
In some teams, Candace's hold Skill cooldown is too long for rotations to work properly. If Candace is not C4, avoid getting hit and use a tap Skill as quickly as possible.
