Secret Room

A Secret room is a hidden room that can occasionally be found inside dungeons during expeditions.

Content
Secret rooms will always contain a special curio that can only be found inside them: the Ancient Artifact, which will drop a small quantity of valuables or, if opened with a Skeleton key, will provide loot similar to that obtained when defeating The Collector. As for every item providing loot, additional items are awarded if opening it while at low or zero light level.

Accessing secret rooms
To enter a secret room, it has to be scouted first. When scouting, eventual secret rooms will appear along a corridor; their position will be indicated by a golden star icon. Upon reaching the corridor segment holding the hidden door to the secret room, the room has to be accessed by clicking in the background or pressing the up arrow as would be done to enter a regular door. Once explored, the secret room can be left by clicking on a new destination room.
