When completing the tasks of the "Explore location with Night mode active" mini-event, you can explore locations having any anomaly that darkens the location, namely Sinister Shadows, Night Terrors, and Electrum.
If you need to explore a location with the Silhouettes mode active, you can also select locations with the Night Terrors anomaly.
Accordingly, if you need to find Pairs of items, you can also explore locations with the Bats and Sinister Shadows anomalies.
For tasks involving Abracadabra mode, you can also explore locations with the Bats and Electrum anomalies.
