Banner & Updates The Spring Login event runs alongside the latest game version rollout. No new recruitment banners or rerun pools are associated directly with this login campaign; instead, the focus is purely on daily login engagement and currency generation. If you're already investing in passage progression or prepping for future operator banners, this is a natural opportunity to stack Oroberyl ahead of upcoming gacha phases (exact recruitment schedules are not stated in official materials as of this patch). Should You Participate? Missing a single day means forfeiting those specific rewards permanently, as unclaimed rewards are not reissued. For F2P and low-spend players, daily claims are not optional—they translate directly into faster banner pulls, operator upgrades, and sanity regeneration. Key takeaways: – Log in every day before the daily reset—set reminders if needed. – Prioritize claiming to avoid leaving Oroberyl or boosters on the table. Gacha account optimization starts with maximizing event attendance, not just roll efficiency. – Advanced players can stack emergency boosters for targeted farming or event-limited content pushes. Event Participation Requirements & Tips You must clear Chapter I Process I: Break the Siege to unlock. This is an early, new-player-accessible milestone. Most progression-focused players will meet this requirement before the event concludes. There is no stated alternative access method. For monthly pass holders: Both the Pristine Monthly Pass Tribute and standard Monthly Pass can run concurrently. Their daily claims are separate, but each has a 30-claim ceiling during the event. It's a rare double-dipping period worth exploiting if you already invest in sustained logins. Teams, Synergies & Currency Impact How do these rewards support your broader goals? Oroberyl is the standard gacha and resource currency; banking an extra 6000 gives leverage for future banners or emergency operator refreshes. Emergency Sanity Booster and Sanity Usage Permit directly increase farming throughput, letting endgame-focused players rush key material nodes, especially during limited events. Pairing boosted sanity recovery with a focused team composition can power up core operators before the next major content push, minimizing stamina bottlenecks in late-game progression. Optimal Claiming Summary: F2P & Competitive Guidance Aim for uninterrupted login streaks—there's currently no event catchup mechanism. Save Emergency Sanity Boosters for limited events, resource grinds, or critical upgrade windows. Track your total Oroberyl to time major multi-pulls more efficiently. Note: The event’s structure aligns with established gacha engagement tactics: daily routines reinforce habit, and even low-investment players can’t afford to miss days. This is foundational for competitive meta-building and F2P progression long term. For official event clarifications and FAQs, see the in-game Event Center on your corresponding server.
