Lowers the effectiveness of Rock-type moves on the user by one level for one round. One use per battle.
This small yellow berry is often pickled due to its dry flavor. A Pokémon holding this item may consume it to reduce the effectiveness of Rock-type attacks made against it by one stage for one round. (Thus, a 2× weakness to Rock would become a 1.5× weakness to Rock for one full round after a Charti Berry was consumed.)
