Everstone is a unique item in the Pokémon series with several notable effects and applications:
Prevention of Evolution: The primary function of the Everstone is to prevent a Pokémon from evolving. When held by a Pokémon that can evolve, the Everstone stops the evolution process that would otherwise occur through leveling up or other evolutionary triggers. This can be particularly useful for trainers who wish to keep their Pokémon in its unevolved form for reasons such as moveset optimization, aesthetic preference, or competitive strategy.
