Lowers the effectiveness of Poison-type moves on the user by one level for one round. One use per battle.
Although a bright green on the outside, this berry has a black pulp. A Pokémon holding this item may consume it to reduce the effectiveness of Poison-type attacks made against it by one stage for one round. (Thus, a 2× weakness to Poison would become a 1.5× weakness to Poison for one full round after a Kebia Berry was consumed.)
