Effect
A protective item. Stiff and heavy.
Level up Rhydon while holding this to get Rhyperior. Huge Attack and Defense but watch out for Water and Grass - 4x weaknesses hurt.
Wild Rhydon sometimes hold these which is convenient. Rhyperior hits like a truck if you can keep it away from its weaknesses - take a while to get the item though.
