Top Astra Yao W-Engines in Zenless Zone Zero

Astra Yao: A Unique Support Character in Zenless Zone Zero

Astra Yao stands out in Zenless Zone Zero as a remarkable Support character, primarily due to her ability to remain active while enabling her team to seamlessly switch between two other allies. What truly differentiates her is her unique skill set, especially the effective energy-draining capability she demonstrates in her Idyllic Cadenza state, providing one of the most beneficial boosts in the game.

Despite her impressive attributes, Astra Yao’s performance can be significantly enhanced with the right W-Engines. Many of the W-Engines available not only improve her existing skills but also introduce new features such as energy regeneration, heightened buffs, and prolonged Chord counts for her Idyllic Cadenza state.

7.[Reverb] Mark I

Base Stat	475 Base ATK
Advanced Stat	20% ATK
W5 Effect	Activating an EX Special Attack boosts all squad members’ Impact by 12% for 10s. This effect can be triggered every 20s, and passive effects of the same nature do not stack.

Although [Reverb] Mark I boasts a 12% Impact increase for squad members, its effectiveness is limited for Astra Yao. As a Support, this passive effect isn’t particularly advantageous. However, if [Reverb] Mark II is not available, the 20% ATK provided by this 3-star W-Engine’s Advanced Stat could still be beneficial.

6.[Reverb] Mark II

Base Stat	475 Base ATK
Advanced Stat	40% Energy Regen
W5 Effect	Launching an EX Special Attack or Chain Attack boosts all squad members’ Anomaly Mastery and Anomaly Proficiency by 16 for 10s. This effect can trigger every 20s without stacking similar passive effects.

The [Reverb] Mark II W-Engine greatly enhances Astra Yao’s capabilities, especially in scenarios involving Anomaly characters. Notably, it offers her 40% energy regeneration from the Advanced Stat. While the low Base ATK might require her to focus more on Drive Disks, [Reverb] Mark II serves as a solid option in the absence of stronger 4-star W-Engines.

5. Slice of Time

Base Stat	594 Base ATK
Advanced Stat	20% PEN Ratio
W5 Effect	Any squad member’s Dodge Counter, EX Special Attack, Assist Attack, or Chain Attack generates additional Decibels and Energy for the equipping character. This effect, available every 12s, increases depending on attack type.

Slice of Time serves as a potential fallback option for a 4-star weapon, offering useful yet modest effects with its PEN Ratio and Energy provisions. However, its limitations on triggering frequency may fall short for Astra Yao’s rapid-swap playstyle.

4. Unfettered Game Ball

Base Stat	594 Base ATK
Advanced Stat	50% Energy Regen
Effect	When the equipping character triggers an Attribute Counter effect, the squad’s CRIT Rate against the affected enemy rises by 12% for 12s. Similar passive effects do not stack.

The Unfettered Game Ball W-Engine is particularly niche yet valuable for Astra Yao, offering a team-wide Critical Rate boost that is triggered by her Ether attacks. Coupled with the 50% Energy Regen, this W-Engine helps sustain her effectiveness in battle.

3. Kaboom the Cannon

Base Stat	624 Base ATK
Advanced Stat	50% Energy Regen
W5 Effect	When any ally attacks an enemy, the squad’s ATK increases by 4% for 8s, stacking up to 4 times. Each stack’s duration is unique, allowing various squad members to contribute to the buff.

Though primarily associated with Lucy, the Kaboom the Cannon can still effectively be used by Astra Yao. She can consistently trigger multiple stacks with her frequent hits, enhancing overall squad damage in the process.

2. Bashful Demon

Base Stat	624 Base ATK
Advanced Stat	25% ATK
W5 Effect	Enhances Ice DMG by 24% and increases ATK when launching an EX Special Attack, stacking up to 4 times.

While at first glance, the Bashful Demon may not seem ideal for Astra Yao due to its focus on Ice DMG, it offers valuable 25% ATK from its Advanced Stat, making it a top-tier choice for boosting team effectiveness.

1. Weeping Cradle

Base Stat	684 Base ATK
Advanced Stat	24% PEN Ratio
Effect	When off-field, Energy Regen increases by 0.6/s, and attacks enhance the squad’s damage against the target.

Undoubtedly, the most powerful W-Engine for Astra Yao is her Signature W-Engine, Elegant Vanity. This 5-star exclusive not only increases her ATK% but also optimally supports energy management, allowing her to maintain her Idyllic Cadenza state and maximize team damage output. The W-Engine’s mechanics have proven essential in establishing Astra as a top-tier Support character in Zenless Zone Zero.
