The Moon Stone is an evolution item in Pokémon Legends: Arceus that can be found as a random item in the wild or obtained using the Trading Post. Players will only need the Moon Stone to evolve Clefairy into Clefable in Pokémon Legends: Arceus. If players don't want to randomly come across a Moon Stone while exploring, then they can trade Merit Points for the evolution item at the Trading Post in Jubilife Village.
Merit Points are a new type of currency in Pokémon Legends: Arceus and players can use them to purchase items at the Trading Post, including the Moon Stone. Merit Points are earned through the Lost and Found system, so players will need to turn on their Internet connection to find and return Lost Satchels. There are other evolution stones and various items available at the Trading Post in Jubilife Village in Pokémon Legends: Arceus, but some are more expensive than others. A Moon Stone will cost players 1,000 Merit Points.
If players don't want to save up Merit Points to use at the Trading Post, then they can search for a Moon Stone while roaming around in the wild. Once players obtain the rideable Ursaluna, they can use it to find hidden items. However, players may need to spend a lot of time searching because the items are randomized, so finding a Moon Stone using this method can be difficult. After players find or purchase a Moon Stone, they can use it to evolve their Pokémon.
Using a Moon Stone in Pokémon Legends: Arceus
A Moon Stone is generally used to evolve Fairy-type Pokémon. In Pokémon Legends: Arceus, players will only need the Moon Stone to evolve Clefairy into Clefable. Players can find and catch Clefairy in the Fabled Spring area in the Coronet Highlands. Alternatively, players can find and catch a Cleffa, one of Pokémon Legends: Arceus's baby Pokémon. However, players will need a high friendship with Cleffa to evolve it into Clefairy.
Once players have a Clefairy, they can give it a Moon Stone to hold. The next time Clefairy levels up, it will evolve into Clefable as long as it has the Moon Stone as a held item. Clefable can't be found or caught in the wild, so players will need to evolve a Clefairy in order to add a Clefable to their party or complete their Pokédex in Pokémon Legends: Arceus.
Completing the Pokédex in Pokémon Legends: Arceus is one of the major goals of the game. Players will need to study and learn new details about the Pokémon they capture to advance the story and grow with the Galaxy Team. Catching and evolving Cleffa and Clefairy is essential to finishing every entry in Pokémon Legends: Arceus's Pokédex. The Moon Stone is an important item for players that want to complete the story in Pokémon Legends: Arceus.
Pokémon Legends: Arceus is available for Nintendo Switch.
