Events & Rewards: Should You Prioritize Excaliboo?
Key Tasks
- Talk to Coach Aster at Scott Outpost to begin the event.
- Guide your Bangboo through progressively difficult combat assessments targeting Ethereals. Expect new rules or modifiers per stage, emphasizing strategic experimentation.
- Progression is stage-gated and partially time-locked.
Notable Rewards
- Exclusive Bangboo: Excaliboo (event-limited, likely high utility for future synergy teams).
- Hamster Cage Pass: Typically redeemed for event shop goods; may offer rare enhancement items or additional Polychromes.
- Polychromes: Premium gacha currency for acquiring new agents or Bangboo (banner pulls).
- Upgrade Materials: Includes core resources for agent and Bangboo progression.
F2P and low-spend players should absolutely prioritize full completion to maximize Polychromes and secure Excaliboo, which could see high value in later meta or rerun events.
What to Do Now: Actionable Strategies
Eligibility Checklist
- Reach Inter-Knot Level 15—focus on story missions and daily commissions if below requirement.
- Clear Agent Story "Mole in the Hole (I)"—a standard progression point; no shortcut available.
Event Prep & Daily To-Dos
- Log in daily—due to the staggered unlock, missing days can reduce reward totals.
- Build versatile Bangboo teams—event mechanics may heighten value for less-used units. Consider leveling backups and experimenting outside your comfort meta.
- Monitor event shop after each completions—event shops in ZZZ sometimes rotate stock or offer time-limited deals.
- Bank Polychromes—especially if planning for upcoming banners; rewards from Excaliboo may push some F2P accounts over crucial pull/Pity thresholds in late September.
Trend Watch: Meta Implications & Community Response
Industry patterns show a growing emphasis on event-limited mascots or supports that impact long-term play. ZZZ’s introduction of Excaliboo aligns with similar moves in other gacha titles, where F2P-accessible, event-only sidekicks have become essential for competitive and collection-focused players.
Initial player feedback (e.g., r/ZZZ_Community) suggests that the Excaliboo event could drive renewed interest in Bangboo team comps—long considered secondary to agent-focused squads. Watch for a possible meta shift in how players approach Endgame content and PvE challenge modes if Excaliboo’s abilities warrant a build-around strategy.
