Lily Chen Echo Chamber in Zenless Zone Zero: Monster Companions, Dates, and What to Prioritize
Zenless Zone Zero continues to shake up its endgame loop with inventive limited-time events, and the newly announced Echo Chamber event brings a fresh spin on monster duels and Agent rewards. With impactful progression resources and a limited new Agent locked behind the event window, understanding how to maximize your participation from 2025-10-17 10:00 to 2025-11-24 03:59 (server time) is crucial for both free-to-play and competitive players.
Why Echo Chamber Deserves Your Attention Now
Echo Chamber isn’t just another combat gauntlet; it offers a unique blend of monster-collecting tactics and narrative exploration in ZZZ’s ever-expanding universe. The event ties in tightly with current-year progression, locking one of the season’s most significant Agent unlocks—Komano Manato—behind event-clear milestones. Miss the time window, and you’ll lose access to limited rewards and optimal resource boosts you won’t soon see again.

How Echo Chamber Works: Monster Duels & Memory Hunts
Event Structure
After unlocking the event, Proxies can travel to the Echo Chamber in Failume Heights. There, encounters with Lucia and Manato open a portal into Yidhari’s dreamscape—a cleverly designed sequence of turn-based monster battles.
- Team Building: Up to four allied monster companions can be chosen per battle.
- Combat Flow: Players and opponents alternate turns, selecting skills in preset order. Instant Interaction timing (think: active dodging or skill enhancement) adds a real-time layer to otherwise turn-based encounters.
- Monster Collection: Victories allow you to recruit new monsters, expanding tactical choices as the event progresses. Each new Dream Investigation phase escalates both the complexity and available rewards.
Progression & Rewards
Milestones (event missions) grant substantial resources:
– Agent Komano Manato unlock (event-exclusive during this period)
– Hamster Cage Pass (event currency)
– Polychromes (premium pull currency)
– Upgrade materials: Not specified in detail, but traditionally include XP and gear resources
Note: All limited-time event rewards expire at event end (2025-11-24). The event story is permanently archived in Ridu Chronicles—but resource and unit unlocks are strictly time-gated.
Should You Prioritize Echo Chamber?
Pull/Participation Guide
- Participate If:
- You want to secure Komano Manato before any potential rerun (timing uncertain)
- You are seeking event-only monster companions for collection or meta experimentation
- Resource gains (Polychromes, materials) are a priority this patch
- Skip If:
- You’re below Inter-Knot Lv. 15 or haven’t completed “Mole in the Hole (I)” (progress needed)
- You’re solely focused on future banner units and can already clear core content
F2P and low-spend advice:
Focus on clearing all event missions to guarantee all time-limited rewards—especially since Polychrome supply may impact your gacha plans for upcoming banners. Event-limited agents like Manato could be meta-essential for months.
Teams & Synergy: What Agents to Pair
Making the most of monster companions requires matching their skill types to your core Agent team. While the event’s rules naturally limit meta team composition, consider these general pairings:
- Tech Agents with high crowd control can buy time for slower monsters to use big skills.
- Support-focused compositions are favored, given turn-based pacing and Instant Interaction dodge windows.
- Collectors will want to cycle monsters regularly to expand the event Pokédex and secure all synergy bonuses.
For players lacking depth, prioritize monsters with stun/interrupt potential, boosting your margin for error in later rounds.
Preparation Checklist: What to Have Ready
- Complete Main Season 2, Chapter 4 story for full lore integration
- Inter-Knot Lv. 15 minimum
- Finish “Mole in the Hole (I)” Agent story quest
- Clear daily event missions for max progress
- Reserve time during each phase unlock (new Dream Investigation stages go live as event ticks forward)

Conclusion: Don’t Miss the Echo Chamber Window
With a limited event window, exclusive Agent unlock, and a fun twist on the game’s formula, Echo Chamber fits squarely in the category of must-play for all active Zenless Zone Zero users this patch cycle. Even if you typically focus on banners or endgame, the sheer value—and FOMO—make this a high-priority goal before 2025-11-24. For ongoing coverage, in-depth guide updates, and tier list shifts.
