Effect Spore (Japanese: ほうし Spore) is an Ability introduced in Generation III. Seven Pokémon can have this Ability, all of them Grass types.


In battle

Generations III to V

When a Pokémon with this Ability is hit by a move that makes contact, there is a 30% chance that the attacking Pokémon will be become paralyzed, asleep or poisoned.

Effect Spore has a 9% chance of inducing poison, 10% chance of inducing paralysis, and 11% chance of inducing sleep.[1]

If a Pokémon with this Ability is hit by a multi-strike move that makes contact, each hit has an independent chance to activate this Ability.

Generation VI

Grass-type Pokémon, Pokémon with Overcoat, and Pokémon holding the Safety Goggles are now immune to Effect Spore.

Outside of battle

Effect Spore has no effect outside of battle.
