Event Details

During the event, Proxies return as temporary detective assistants for The Hobbling Crow Detective Agency. The case centers on a poisoning incident and the strange events surrounding it.

The event is split into five commission incidents: "Poison Before Sleep," "Crow's Footprints," "The Nonexistent Server," "Scarecrow and Crow," and "Shadows in the Cup." Each commission unlocks only after completing the previous one and reaching a specified time, so progress is gated by both story completion and the event calendar.

Rewards and Planning

Completing the event commissions grants a Tuning Calibrator, Polychromes, and various upgrade materials. The exact quantities are not stated in official materials.

For F2P players, the Polychromes are the headline reward and worth prioritizing before the event ends on 2026-11-30. Low-spend and optimal players should also clear the commissions for the Tuning Calibrator and materials, which can offset upgrade costs elsewhere.

What to Do Now

• Confirm your Inter-Knot Level is at least 20 and that Chapter 1 – Intermission is complete.
• Clear the first commission as soon as the event opens on 2026-11-11 to avoid time-gated bottlenecks later.
• Track the unlock schedule for each subsequent commission; the final one may require waiting until closer to the end date.

Takeaway

Poison Before Sleep is a straightforward detective-themed event with Polychromes and a Tuning Calibrator on the line. Meet the prerequisites early and clear each commission as it unlocks to finish well before 2026-11-30 03:59 (server time).
