Pokémon with Immunity do not take poison damage outside of battle. Prior to Generation V, outside of battle, all poisoned Pokémon in the player's party lose one HP every four steps the player takes (every five steps in Pokémon FireRed and LeafGreen). If a Dynamaxed opponent in a Max Raid Battle becomes badly poisoned, it will instantly become normal poison. Poison- and Steel-type Pokémon can be poisoned by a Pokémon with the Ability Corrosion. Poisoned Pokémon take double damage from Hex and Venoshock. Steel-type Pokémon can no longer be poisoned by any moves, including Twineedle.Īt the end of the battle, bad poison now becomes regular poison. Poison damage is now taken at the end of each turn, regardless of whether a Pokémon faints.Ī badly poisoned Pokémon will remain badly poisoned even if switched out or the battle ends, although the counter is reset. While Steel-type Pokémon cannot be poisoned by Poison-type moves, they can be poisoned by Twineedle. If a badly poisoned Pokémon successfully uses Rest, it will be cured of poison, but N is not reset if it then suffers burn, Leech Seed or poison damage, that damage will draw upon the N value, and the N value will still increase by 1 each time (however, if the Pokémon is poisoned with Toxic, the N value will be reset to 1).Ī poisoned Pokémon will take damage equal to 1/8 of its maximum HP each turn.īad poison damage no longer interacts with other types of recurrent damage. If a Pokémon badly poisoned by Toxic is also under the effect of Leech Seed, both types of recurrent damage will draw upon the same N value to calculate how many multiples of 1/16 of the Pokémon's HP is taken as damage, and both will increase that value. When a badly poisoned Pokémon is affected by Haze, switches out, or when the battle ends, its poison status becomes regular poison.

The damage stops increasing when it equals 15 × ⌊ H P m a x 16 ⌋. Outside of battle, all poisoned Pokémon lose one HP for every four steps taken.Ī badly poisoned Pokémon takes damage equal to 1/16 of its maximum HP (rounded down, but set to 1 HP if it would be less) on the first turn, after which damage increases by 1/16 each time it takes poison damage. If a poisoned Pokémon causes an opponent to faint, the poisoned Pokémon will not take damage that turn. The exact amount of damage varies between generations.Ī poisoned Pokémon will take damage equal to 1/16 of its maximum HP every turn, after it attacks, or at the end of the turn if it did not attack.

Regular poison inflicts a fixed amount of damage each turn, while bad poison inflicts an increasing amount of damage each turn. In battle, a poisoned Pokémon takes damage each turn.
