Effect
Generations I to II
When used from the Bag during battle, it makes the Pokémon's moves ignore accuracy checks. It also allows one-hit knockout moves to always hit but will still fail if the target has a higher Speed (in Generation I) or level (in Generation II) than the user.
Generations III to VI
When used from the Bag during battle, it raises the accuracy of a Pokémon currently in battle by 1 level. It also increases the Pokémon's friendship a little. One-hit knockout moves are no longer affected by X Accuracy.
Generation VII onward
When used from the Bag during battle, it raises the accuracy of a Pokémon currently in battle by 2 levels. It also increases the Pokémon's friendship a little. One-hit knockout moves are unaffected by X Accuracy.
