Guaranteed No-Loss Banner! Is Astra Yao Still Worth Pulling?Comparison Between Astra and Sunna

Astra Yao Breakdown: Why Has She Stayed T0 for So Long?

As Zenless Zone Zero’s first limited Support agent, Astra Yao has maintained her T0 status for one simple reason:

She’s a universal buffer with absurd consistency.

She doesn’t rely on niche setups or complex execution — just raw, reliable value that works in almost every team.

1️⃣ Extremely Simple Kit, Full Buffs from the Start

Astra Yao is one of the most beginner-friendly supports in the game.

With a single press of her Special Skill, she enters “Aria Brilliance”, immediately granting the entire team:

• 20% universal damage bonus

• 25% CRIT DMG

While this state is active:

• Astra Yao is completely invincible

• Quick Assist triggers automatically

There’s no strict timing or combo requirement — even low-APM players can extract full value effortlessly.

2️⃣ Strong Buffing Power, No Team Restrictions

Her Core Passive grants up to 1,200 ATK to the active agent (fully capped at around 3,429 ATK outside combat).

More importantly, she does not care about team archetypes:

• Attack teams ✔

• Anomaly teams ✔

• Break teams ✔

If Astra Yao is in the squad, the team’s damage output improves immediately. This level of flexibility is exactly why she continues to age well across patches.

3️⃣ Low Investment, Extremely High Value

One of Astra Yao’s biggest strengths is that she does not require her signature W-Engine or dupes to function at a high level.

Even the 4★ W-Engine “Fighting Cannon A-Pao” works perfectly thanks to its high Energy Regen, making her one of the most F2P-friendly limited supports available.

Guaranteed Banner Pull Priority: Should You Pull Astra Yao?

Considering the current meta — and especially the fact that this is a guaranteed no-loss banner — Astra Yao is highly recommended for the following players:

• New or returning players
  Supports are scarce early on. Astra Yao acts as a “universal plug-in” that stabilizes team performance and allows even standard DPS agents to reach acceptable output levels, greatly reducing early-game pressure.

• Players lacking core supports
  If your roster doesn’t include strong buffers like Astra Yao or Lucy, pulling her is almost never a mistake. She fits seamlessly into future teams regardless of which main DPS you pull later.

For most players, a guaranteed banner means zero-risk access to a top-tier support.
As a long-term T0 universal buffer, Astra Yao is unlikely to fall off anytime soon — her raw damage amplification and comfort value age extremely well.

Sunna: Ye Shunguang’s Tailor-Made Physical Support

After Ye Shunguang released, Physical teams faced a long-standing issue: a lack of properly optimized support.

In current Physical-focused lineups:

• Lucy’s buffing potential is limited

• Astra Yao doesn’t fully optimize Physical scaling

• High-investment Ye Shunguang struggles to reach her true damage ceiling

Sunna is designed specifically to solve this problem.

Core Ability: Aether Veil · Idol

When Sunna uses her Enhanced Special Skill or Ultimate, she activates Aether Veil for 30 seconds.

If the team includes an Attack-type agent (such as Ye Shunguang), the effect additionally grants:

• +15% CRIT DMG

This synergizes perfectly with Ye Shunguang’s high-multiplier Physical burst playstyle, maximizing CRIT DMG efficiency and significantly raising the team’s upper damage limit.

Astra Yao vs Sunna — Is It Really a One-or-the-Other Choice?

Many players frame this as a strict “pick one” decision, but in reality, their roles are not identical.

• If you already own Astra Yao or other strong universal supports
  👉 Sunna becomes the better upgrade, especially for Physical comps. She’s a ceiling-raiser and likely a long-term staple for Physical teams.

• If your account lacks reliable supports overall
  👉 Astra Yao remains the safest and most flexible option.

There’s no need to worry that Sunna invalidates Astra Yao.

Astra Yao’s pure damage amplification and ease of execution remain irreplaceable in many general scenarios.
Sunna simply excels in Physical-focused environments — she is not a universal power-creep replacement.

Final Verdict

Both Astra Yao and Sunna are top-tier supports with clearly defined strengths.

• Plenty of resources?
  Pull both — universal value plus Physical specialization.

• Only choosing one?

  • Need a general-purpose support → Astra Yao

  • Running Physical / Ye Shunguang teams → Sunna

In the end, the smartest choice is simple:

Pull based on your roster’s actual needs — not banner hype.
