Lowers the effectiveness of Normal-type moves on the user by one level for one round. One use per battle.
A berry banded in different shades of yellow that can be converted into a whistle with a haunting sound. A Pokémon holding this item may consume it to reduce the effectiveness of Normal-type attacks made against it by one stage for one round. (Thus, neutrality to Normal would become a 0.67× resistance to Normal for one full round after a Chilan Berry was consumed.)
