EarlyGG Sān-Z STUDIO Event Arrives in Zenless Zone Zero: Full Guide & Collectible Rewards (2025/10/04–2025/10/13 Server Time)
The Sān-Z STUDIO event lands in Zenless Zone Zero with a mix of exclusive Bangboo collectibles, new story integration, and a highly F2P-friendly redemption system. Running from 2025-10-04 10:00 to 2025-10-13 03:59 (server time), this time-limited event offers both dedicated and casual players meaningful ways to engage and collect unique items—even after the core period ends.
Recent event structures in HoyoVerse titles have trended toward greater accessibility and post-event reward coverage. This event continues that momentum, lowering the stakes for new players while still incentivizing timely participation. Here’s what every Proxy needs to know to maximize rewards, plan their dailies, and choose their ideal collectible.
At a Glance: Sān-Z STUDIO Event Summary
- Duration: 2025-10-04 10:00 – 2025-10-13 03:59 (server time)
- Requirements: Reach Inter-Knot Lv. 15 & complete Agent Story: Mole in the Hole (I)
- Location: Initiate at Sān-Z STUDIO, Lumina Square by speaking to Ellen
- Event Currency: Nine mysterious treasures to collect via time-gated event commissions
- Event Rewards: 1x Bangboo Garden Kingdom collectible (choice), Polychrome, upgrade materials
- Missed Selections? All exclusives become infinitely redeemable post-event
Event Structure & Reward Details
During the event window, players unlock nine time-gated commissions by checking in with Ellen at Sān-Z STUDIO. Completing each commission yields event points toward Bangboo’s wish, "Adrift Half a Year", and unlocks parts of the treasure collection. Once all tasks are done, Proxies select a single collectible from:
- Bangboo Garden Kingdom: Sweet Summer Days
- Health Plan
- The Veggie Squad
All unselected items are not lost—after the event closes, any missed choices become permanently obtainable at Sān-Z STUDIO through an in-game redemption mechanism. This safety net stands out amid gacha industry concerns about FOMO-driven exclusivity. In addition, Polychrome and various upgrade materials support both active and returning players.
Official materials do not specify event-gacha connections, additional banners, or drop rates for this event.

| Start Location | Sān-Z STUDIO, Lumina Square |
| Main NPC | Ellen |

What Sets This Event Apart
While time-gated event commissions are familiar territory for Zenless Zone Zero players, the Sān-Z STUDIO event’s permanent collectible system is notably forgiving. This mirrors trends elsewhere in the gacha genre, as publishers lean into long-tail retention over one-off exclusivity.
Completing the event within the active window still matters: timely selection lets you personalize your collection first, while the bonus Polychrome and upgrade materials optimize on-account progress. Proxies who miss the final selection, however, are shielded from permanent loss—an increasingly rare approach among top-tier gacha titles.
Recommended Strategy for F2P and Optimizers
- Set daily reminders during the event window (2025-10-04 to 2025-10-13) to complete each commission promptly; all nine must be collected for maximum efficiency.
- Choose your Bangboo collectible on event end: Prioritize visual appeal if collecting, or sentimental value if following storylines. Meta utility is not outlined in official sources.
- Upgrade materials and Polychrome should be reserved for upcoming banners. At press time, no event-tied banners are mentioned in official communications.
- Post-event catch-up: If you’re not able to participate fully, return to Sān-Z STUDIO after 2025-10-13 to acquire all collectibles at your own pace. No penalty for missed event window except delayed ownership.

Industry Perspective
By decoupling collectibles from high-pressure deadlines, Zenless Zone Zero’s event design demonstrates renewed sensitivity to long-term player engagement. As gacha fatigue and exclusivity churn spark debate across the industry, these more accessible event systems could set precedents in both retention rates and community goodwill.
