Gates:Mysteriosity

Mysteriosity (Japanese: 不思議(ふしぎ)) is a game mechanic in Pokémon Mystery Dungeon: Gates to Infinity. It is available in most dungeons after it is unlocked post-credits. Some dungeons are only accessible through Mysteriosity. Dungeons that are affected by Mysteriosity can also be affected by the Strange Power.

Distortions

When going to a floor of a dungeon affected by Mysteriosity there is a chance to trigger a variety of mysterious distortions (Japanese: 不思議(ふしぎ)な　ひずみ). On each floor there is either no distortion, one single distortion, or two distortion.

Enemies stronger or weaker than usual means they are leveled up or down respectively.

Categories

Each distortion belongs in one of three categories. Distortions in the Single category always happen alone, while effects in the Combo categories happen in pairs of two effects, one from the first Combo category, and another from the second.

Levels

Mysteriosity levels go from 0 to 5 and are displayed with an icon next to the name of the dungeon, or on the bottom screen when going to the next floor. They determine the probability of distortions on each floor of a dungeon. Dungeons where Mysteriosity is available have a random level on each in-game day when accessed from the Crossroads, however jobs have a Mysteriosity level tied to them that stays the same regardless of the day.

First, the level determines the category of a floor.
