Treasure Scanner/es

The Treasure Scanner is a type of Oak Item. When equipped, it provides a chance to multiply mined items in the Underground. It only starts taking effect upon fully uncovering an item. After duplicating an item, it activates again, providing another chance to reward the same item. This can happen a maximum of three times, potentially giving four of the same item after uncovering one. Unlike most other Oak Items, it is not unlocked by capturing unique Pokémon and instead can be bought from the Cinnabar Island Shop in Kanto.
