Status conditions in the Mystery Dungeon series

Whereas in the core series a Pokémon can only be afflicted with one major status condition and a number of volatile minor status ailments, the Mystery Dungeon series allows Pokémon to be afflicted by multiple status conditions.

Status conditions can be caused by a variety of ways, such as from the effects of moves (such as the Sky Attack status, which is a self-inflicted condition due to the use of ), IQ skills (such as the Pierce status from Pierce Thrower), and items (such as Mobile from the ).

Stat drops and boosts are also listed as 'weakened' and 'boosted' status conditions in-game. When the Pokémon's HP drops below 25%, the game also lists this as a 'low HP' status condition. However, these conditions do not interact as usual status conditions and are not considered bad status conditions.
