Astra Yao

When Astra Yao's attack hits an enemy, the target's All-Attribute RES is reduced by 6%, stacking up to 3 times and lasting 30s. Repeated triggers reset the duration. Upon entering the battlefield, Astra Yao immediately gains 1,000 Decibels (once every 180s in Investigation Zone Mode). When activating her Ultimate, all squad members gain 1 stack of Song of Protection for 60s — when attacked by an enemy, consume Song of Protection to grant Invulnerability for 1s.

The ATK buff from Core Passive: Graceful Andante is further increased by 19%, with an increased maximum of 400. While in the Idyllic Cadenza state, when other squad members switch in through a Quick Assist, Chain Attack, Defensive Assist, or Evasive Assist, Astra Yao additionally follows up with 1 Tremolo and 3 Tone Clusters. This effect can trigger once every 3s.

Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2.

After activating a Chain Attack or Ultimate, within 15s, Astra Yao can trigger a Quick Assist even without Chords. When the attack hits an enemy, the Quick Assist interval is reduced to 1s. While in the Idyllic Cadenza state, when other squad members enter via a Quick Assist, they receive specialty-based buffs (once every 3s per squad): Attack — the next Quick Assist heavy attack deals extra DMG equal to 300% of Astra Yao's ATK; Anomaly — next Quick Assist has 50% increased Anomaly Buildup; Stun — next Quick Assist inflicts 50% increased Daze.

Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2.
