Ripen doubles the effects from held Berries when eaten in battle, including when a Pokémon with Ripen is targeted by a flung Berry. This affects Berries that restore HP or PP (such as Figy Berry and Leppa Berry), Berries that reduce damage (such as Occa Berry), Berries that raise stats (except for Lansat Berry), and Berries that deal damage to Pokémon attacking the holder (such as Rowap Berry). Ripen does not affect the status condition-healing Berries (e.g. Persim Berry or Lum Berry), the Lansat Berry (i.e. Ripen will not make it increase the critical hit stage by 4), the Micle Berry, or the Custap Berry (although it will still show the message).
Due to a glitch, when a Pokémon with Ripen uses certain non-Berry items or is targeted by a flung item that inflicts a secondary effect, Ripen displays a message and plays its animation, but has no other effect. The items affected are as below:
