W-Engine
Astra's signature: ATK% to help cap her Core Passive buff, passive Energy generation from every Quick/Chain/Defensive/Evasive Assist, and a team-wide up-to-20% DMG% boost she maintains indefinitely.
Soukaku's signature at S5 is a top competitor — ATK% for the Core Passive cap plus a 12.8% team-wide Combat ATK buff that Astra builds effortlessly via her Tremolo triggers.
Lucy's signature at S5 posts the highest Shiyu scores — 50% Energy Regen and a 12% team ATK buff. Requires each member to hit an enemy every 4s, which Quick Assist management keeps under control.
Nicole's signature provides 50% Energy Regen and a 24% team DMG buff on skill hits, but only lasts 2 seconds — demands tight play to outpace Bashful Demon or Kaboom.

12-Tone Equal Temperament
PriorityWhen 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.
