Youhu is a new 4-star resonator joining the Wuthering Waves roster in version 1.3. Excitingly, she is a sub-DPS unit who can also heal to some extend, which makes her especially attractive to players looking to tackle the Tower of Adversity but have been struggling with a lack of solid sustain / sub-DPS optionsparticularly if they haven't built Baizhi or don't plan on pulling for Shorekeeper.
