The ultimate Berrys Guide

The concept of Pokemon trainers collecting berries to aid their teams is by no means new to Diamond and Pearl. However, with each passing generation, the significance behind berry collection and utilization has become increasingly notable. The proper utilization of berries can help you to gain an edge in battle.
Becoming Familiar with Berries

Berries are unique in that they can be used by Pokemon automatically during battle when a specific condition is met. An example of such a condition is a Pokemon's HP falling below 50%. Keep in mind that each attached berry may only be used once unless a Pokemon that has already consumed a berry uses the move Recycle.
