If Haunter is your Active Pokémon and is damaged by an opponent's attack (even if Haunter is Knocked Out), the Attacking Pokémon is now Poisoned.
Choose 1 of your opponent's Pokémon. This attack does 20 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
It likes to lurk in the dark and tap shoulders with a gaseous hand. Its touch causes endless shuddering.
