Midnight Anomaly Database
Night Anomalies & Yokai Guide
Midnight anomalies use several trigger systems. Some are targeted with Plaques on the Haunted Shelf, some are random after progression, and others require Rain, Thunderstorm or Snow. Weather controls eligibility where canonical, but it is not a guaranteed spawn rule.
