Astra Yao is primed to take over as the top Ether support unit in , but how and where does she shine best? Astra Yao is the second 5-Star Ether agent to join, and will likely kick Nicole out of her role.
Though their kits differ, the benefits a 5-Star will bring over 4-Stars will always be evident. However, Nicole will still be a viable pick for secondary teams, or if players choose to skip over Astra. Astra's kit revolves around, Quick Assists, Chain Attacks, and her Idyllic Cadenza state.
This state, which she enters through her EX Special, Ultimate, or Chain Attack, allows her to increase her team's damage, attack, and critical damage.
Also, if Astra has any Chords, which are made up of 25 energy, she can allow teammates to trigger Quick Asists early. This all culminates with an extremely helpful Ultimate that allows Astra to heal her team and deal an initial blast of Ether damage.
As usual, Astra's signature W-Engine, Elegant Vanity, will be her best option. First, this engine gives flat Attack and Attack%, which is crucial for her since her Attack buffs scale off her stats.
