Anime Zero Astra Yao

In-game class "Astral Blossom" — the first dedicated support among the Lyth units, and the winning-formula second slot: one main damage weapon plus this. M1 is a wide mid-range sound wave with built-in knockback; Skill 1 groups mobs and applies Astra's Aura (+50% damage, +25% speed, 8s — numbers confirmed by two creators); Skill 2's spinning vortex refreshes the Aura timer and heals via lifesteal (lifesteal single-source) — the sustain core against hard-hitting bosses; Skill 3 adds Astra's Cheer (+20% damage, 10s — +70% total); the ultimate concert pushes it to +80% damage / +25% speed / 10s. Buffs apply at full value to the whole party and both of your weapon slots, persist through weapon swaps, and refresh rather than stack. Slow attack speed keeps her out of main-DPS duty. The Oct 13 patch made the buffs stronger and last longer. Best duo: behind Ye Shunguang (two sources).

Astra Yao is inspired by Astra Yao (Wuthering Waves). Origins are community-identified — the game uses original character names, and this site words origins strictly as "inspired by".

Trials — in-game class "Astral Blossom": clear room 75 co-op (current — two creator sources, Oct 12–13; originally 150 before the requirement nerf). One creator suggests solo may also qualify (unconfirmed).

Tier placements are community consensus, not official data. Each source and date is listed so disagreements stay visible.

Astra Yao occupies one of two loadout slots. If it is your stronger pick, keep it in slot one and put a coverage weapon in slot two; swap mid-dungeon with T as cooldowns demand.
