When the Pokémon hits a target with a contact move, the target has a 30% chance of being poisoned.
Poison Touch (Japanese: どくしゅUnderhanded Trick) is an Ability introduced in Generation V.
Effect
In battle
If a Pokémon with this Ability uses a move that makes contact, there is a 30% chance the target will become poisoned. In Japanese versions of Pokémon Black and White, this is a 20% chance instead.
This chance applies independently of any moves that may have a chance to poison the target with their own effect. If the attack's target holds a status condition-curing Berry, it is possible for a move's natural effect to inflict a status condition which the target's held item will then cure, only for the target to then be poisoned by Poison Touch. Poison Touch's chances also apply independently for each hit of a multistrike move.
In a link battle including a Japanese version of Pokémon Black or White and non-Japanese version of Black and White (or any version of Black 2 or White 2), the chance to poison is determined by the game of the player with the Pokémon that has the Ability Poison Touch. As such, a Pokémon with Poison Touch owned by the player of a Japanese version of Pokémon Black or White will have a 20% chance to poison, whereas players of Pokémon Black 2 and White 2 and non-Japanese versions of Pokémon Black and White will have a 30% chance.
May inflict the Poisoned status on the attacker who hits it with a direct attack.* When the Pokémon lands a direct attack like Tackle or Scratch, the target is sometimes afflicted with the Poisoned status condition!*
This Ability's Japanese, Korean, and Chinese names are a pun; 毒手 Dokushu is a figure of speech meaning treachery or an underhanded scheme, but the individual characters 毒 and 手 literally mean "poison" and "hand/touch", respectively.
