The user scatters bursts of spores that induce sleep.
Spore puts the target to sleep. Spore cannot affect targets with Insomnia or Vital Spirit as their Ability. Grass-type Pokémon, are also unaffected, even if they are holding a Ring Target (which removes type immunities).
Pokémon with Overcoat, and Pokémon holding the Safety Goggles are now immune to Spore.
Pokémon under the effect of Sweet Veil are also unaffected by Spore.
