Alex Rodriguez Sunna Build Guide in Zenless Zone Zero: Optimal Loadouts & F2P Tips
Published: 2026-02-06 | Patch: 1.0 (Global servers, UTC+0)
Sunna has quickly established herself as a premier support unit in Zenless Zone Zero (ZZZ), thanks to her blend of strong team buffs, rapid Energy generation, and flexible synergy with top Attack agents. With the latest banner cycles concluded, players are revisiting support priorities—making it the perfect moment to reassess Sunna’s build for both F2P and low-spend rosters.
Why Sunna Deserves Your Resources Now
- With ZZZ’s endgame content scaling rapidly in the last two updates, turn-efficient EX Special Attacks and universal buffs matter more than ever. Sunna’s presence on a team isn’t just about keeping up; she accelerates both damage and survivability for frontliners.
- As banner overlap and rerun speculation swirl, resource allocation is top-of-mind—especially for F2P and smart budget players hoping to punch above their Battle Pass bracket.
At a Glance: Sunna Loadout Recommendations (Patch 1.0+)
- Recommended W-Engines: Thoughtbop (S), Kaboom the Cannon (A), Slice of Time (B/conditional)
- Drive Disc Sets: Full 4pc Moonlight Lullaby, or 2pc Moonlight Lullaby + 2pc Swing Jazz (for Energy stacking)
- Stat Priorities: ATK% (Disc 4/5), Energy Regen (Disc 6)
- Synergy Anchor: Best paired with top-tier Attack Agents (e.g. Ye Shunguang)
- Ideal for: Players prioritizing bossing and difficult content, especially in F2P-leaning accounts
Best-In-Slot W-Engines for Sunna
A well-chosen W-Engine defines Sunna’s field time, team-wide buffs, and rotational utility. Here’s how top options compare:
| W-Engine | Key Benefit | Role Fit |
|---|---|---|
| Thoughtbop | Passive Energy Regen (off-field), team buff utility | Signature BIS |
| Kaboom the Cannon | ATK% buff on team attacks, Energy Regen substat | Budget/F2P |
| Slice of Time | Conditional regen (triggered by Dodge/Assist/Chain events) | Niche/situat. |
Expert Tip: If you’re lacking Thoughtbop, Kaboom the Cannon covers the basics for non-whale players, especially important given Sunna’s hunger for consistent Energy cycles. Slice of Time can be run on alt comps but is rarely optimal.
Drive Disc Sets: Stats, Substats & Set Effects Explained
Maximizing Sunna’s potential comes down to set effects and stat prioritization. The table below summarizes recommendations for main and substats according to meta sim results (patch 1.0):
| Disc Slot | Main Stat | Why? |
|---|---|---|
| Disc 4 | ATK% | Boosts Sunna’s Core Passive/Team Buff |
| Disc 5 | ATK% | Doubles up on buff source |
| Disc 6 | Energy Regen | Ensures EX uptime when rotated |
Drive Disc Sets:
- 4pc Moonlight Lullaby: Boosts Energy Regen (2pc) and applies team DMG% buff (4pc) on Sunna’s skill use. When fully stacked, provides the highest sustained team uplift—especially relevant for longer boss encounters.
- 2pc Moonlight Lullaby + 2pc Swing Jazz: If 4pc isn’t available or you need to push Energy Regen totals higher on early-game builds.
Substat priority: ATK% > Energy Regen > HP%. Avoid splitting stats with niche defensive rolls unless absolutely necessary.
Visual suggestion: Consider a drive disc comparison chart showing Moonlight Lullaby’s team utility under different skill intervals (Alt text: Charts illustrating Drive Disc set buffs for Sunna at key rotation points, helping players time buffs for boss phases).
Team Synergy: Pairings for Meta and Budget Play
Sunna operates at her peak when synergizing with at least one Attack Agent and a chain facilitator (e.g., an Anomaly or Stun support). Strong candidates include:
- Ye Shunguang: Excels at burst rotations, and Sunna’s buffs directly amplify her EX output.
- Random AP Gains (F2P): Units that can frontload their rotations and benefit from DMG%/ATK% stacking, e.g., Billy, Nicole.
- Budget/Cycling Teams: If you lack top Attackers, Sunna can still provide a meaningful uplift as long as teams have access to regular Chain or Dodge procs for secondary W-Engines.

Sunna’s upgrade path parallels typical ZZZ supports. The table below provides a server-standardized breakdown (UTC+0 resets):
| Material | Source | Daily/Weekly | Total for 6★ |
|---|---|---|---|
| Ether Soul | Anomaly Domains, Shops | Daily | Not stated in official materials |

Troubleshooting: Avoiding Common Sunna Build Pitfalls
- Energy Starvation: If Sunna’s EX uptime is low, immediately rebalance your discs or switch to a higher Energy Regen set until a 4pc Moonlight Lullaby is available.
- Over-investing in Flat HP: Only upgrade substats that impact ATK% or Energy efficiency; don’t succumb to defensive min-maxing on a support not meant to tank.
- Ignoring Weapon Synergy: Kaboom the Cannon is only viable when Thoughtbop isn’t available—do not over-upgrade both for Sunna alone.
Should You Pull Sunna (Patch 1.0)?
For F2P and Sustainable Accounts:
– If you lack a generalist support, Sunna is a high-yield investment due to her wide comp compatibility. Given the 10x warp pity (guaranteed A-rank character every 10 pulls) and banner cycle positioning, budget a multi-rotation plan around her if your team lacks top-tier buffers.
– For whale or meta-chasing accounts, Sunna’s synergy with the current banner’s Attack agents provides a near-instant power spike.
Competing units slated for future banners (dates/leaks unconfirmed — subject to change by HoYoverse) may offer temptation, but Sunna remains a safe, evergreen pick.
Next Steps & What to Watch
- Monitor patch notes for future Drive Disc or W-Engine changes—mid-patch tuning isn’t uncommon in ZZZ’s early service.
- Track upcoming Attack Agent banners: Sunna’s build scales even higher with new DPS releases.
- For materials and weekly cadence refreshes, check EarlyGG’s ongoing ZZZ coverage.
Sunna, properly built, is one of the most future-proof support Agents in the current ZZZ roster—ideal for both newcomers and lategame optimizers.
