Confide lowers the target's Special Attack stat by one stage and bypasses accuracy checks to always hit, unless the target is in the semi-invulnerable turn of a move such as Dig or Fly. Confide will hit the target even if it has used Protect, Detect, or Spiky Shield.
Pokémon with the Ability Soundproof are not affected by this move.
The user tells the target a secret, and the target loses its ability to concentrate. This lowers the target's Sp. Atk stat.
