Astra Yao Best Teams and Bangboo
Astra F2P Team
Free-to-play trio using Astra Yao as Support to buff the team. Billy serves as the primary Attack while Anby provides Stun. Billy can be switched in via Chain Attack instead of Quick Assist.
Astra Generalist Team
Typical DPS setup with Astra Yao as Support, an Attack unit (Evelyn) and a Stun unit (Lighter). Position Astra before the Attack unit to transition from Support to DPS smoothly.
Astra Disorder Team
Astra Yao used in Anomaly/Disorder comps. Pair with Anomaly units (example: Miyabi + Yanagi) to amplify party damage; Miyabi notably benefits from Astra's EX Special Attack buffs.
Astra Rupture Team
Rupture-focused team with Astra Yao as Support, Pan Yinhu enabling Sheer Force via healing (Core Skill), and Yixuan as the Rupture DPS. Astra's healing and ATK buffs synergize with Sheer Force mechanics.
Astra Yao Skill Priority
| Skill | Priority | Explanation |
|---|---|---|
| It's essential to upgrade Astra's Core Skill first since it increases the DMG buff. | ||
| Upgrading Astra's Special Attack is just as important as her Core Skill since this increases the DMG buffs during Idyllic Cadenza state. | ||
| Upgrading Astra's Chain Attack will increase the amount of healing she offers on her Ultimate, so upgrade this after her Core Skill and Special Attack. | ||
| Upgrade this after the high priority ones since it provides the most DMG when Astra is on-field. | ||
| You can save Astra's Dodge for last since it doesn't contribute much to her kit. | ||
| Astra's Assist also doesn't do much in terms of damage. |
