Astra Yao, the S-Rank Ether Support Agent from the Stars of Lyra faction, is making a significant impact in Zenless Zone Zero’s Version 2.0 rerun. Renowned for her ability to amplify team damage through ATK buffs and All-Attribute RES debuffs, she seamlessly fits into various team compositions. This guide provides an in-depth look at optimizing Astra Yao’s build, including W-Engines, Drive Disc sets, and team synergies.

Core Mechanics: Idyllic Cadenza and Team Buffs

This effect lasts for 20 seconds and can be extended up to 30 seconds with repeated triggers. To maximize this buff, it’s crucial to build Astra Yao with a total ATK of approximately 3,430.

Additionally, her Chain Attack reduces enemies’ All-Attribute RES by 6%, stacking up to three times for a total of 18%, lasting 30 seconds.
