Sometimes you need to successfully explore locations with a certain anomaly.
If the anomaly is not present in any location, you can:
- keep playing until the desired anomaly appears in one of the locations,
- summon the anomaly to a random location using an item for summoning anomalies.
When you have an active event quest to complete an event location with a certain anomaly active, there is a greater chance of summoning the anomaly to the location.
