Lowers the effectiveness of Ice-type moves on the user by one level for one round. One use per battle.
This blue-speckled berry is best eaten chilled. A Pokémon holding this item may consume it to reduce the effectiveness of Ice-type attacks made against it by one stage for one round. (Thus, a 2× weakness to Ice would become a 1.5× weakness to Ice for one full round after a Yache Berry was consumed.)
