evolutionary stone
Evolutionary Stones are items in the Pokémon series that, when used on certain Pokémon, allow them to evolve.
A Pokémon who is evolved via Evolutionary Stone will usually have a limited movepool learned via level-up to counter-balance this easy evolution method, but this isn't always the case.
