Mysteriosity
Mysteriosity is a phenomena in PMDO that begins to occur after the player has obtained one of the entercards. It impacts most dungeons in the game.
Obtaining Cards
The cards are obtained as rewards for completing the Family Questline.
Distortion
Each dungeon segment has its own chance of triggering a distortion to spawn. This chance activates when the player obtains their first card. For each extra card that is collected after the first the chance of a distortion happening rises by 2%.
When a distortion triggers, an arrow points the player towards the direction of the distortion. There is a limited amount of time to reach the distortion before it disappears. This time is equal to the Manhattan distance between the spawn and the special exit, multiplied by 3, rounded up to the nearest multiple of 10.
If this distortion is reached in time, it turns into stairs. These stairs will not disappear and can be used to exit the floor to enter a mysterious passage.
Mysterious Passage
A mysterious passage is a special floor with its own unique generation spawned by mysteriosity that depends somewhat on the dungeon the passage was entered on. Special items and Pokémon can be found here.
Several different variants of dungeon generation can be rolled for on entering the passage. The floor entered always wraps around on itself.
