All Pokémon who evolve using the Water Stone in Pokémon Legends: Arceus

Pokémon Legends: Arceus makes numerous changes to the Pokémon series, and one of these is evolution. Pokémon no longer automatically evolve upon reaching a certain level. Instead, they have specific conditions, including level, friendship, items, and more, that allow them to evolve. One of these items is the Water Stone.

The Water Stone is a classic evolution method that originates in Pokémon Red and Pokémon Blue. This evolution method allows various Pokémon, typically water-types, to evolve. In Pokémon Legends: Arceus, only one Pokémon evolves with the Water Stone.

• Eevee: Use a Water Stone on Eevee to evolve it into Vaporeon.

Once you use a Water Stone on Eevee, it is consumed. This means it is a one-time use item, but as Eevee is the only Pokémon to evolve through this method, you don't need multiple unless you want several Vaporeons.

Vaporeon is a great Pokémon for any team, boasting high HP, Special Attack, and Special Defense. Its great bulk gives it high survivability while also letting it land devastating attacks of its own.
