From Bulbapedia, the community-driven Pokémon encyclopedia.
A status move is a move that, in the Pokémon games, does no direct damage, but instead causes a weather condition, status effect, or raises or lowers the stats of a Pokémon during battle. This includes also other attacks which cannot be categorized under physical moves and special moves because of their unique or nearly-unique effects, such as Destiny Bond, Splash, Charge, and Recover.
The majority of Normal- and Template:Type2 moves, as well as the only former Template:Type2 move, Curse, are in this category. Very few moves of the other 15 types are status moves: the Template:Type2 only features one status move, for example, while Fire only features two.
