How to Get Magnezone in Pokémon Legends: Arceus
Players can get multiple Magnetobeasts in "Pokémon: Arceus", or they can be obtained by reaching a specific area to evolve Magnetobeasts.

Magnezone is an Electric and Steel-type Pokémon that players can catch in Pokémon Legends: Arceus, or by evolving Magneton. Magneton is one of many Pokémon in the series that need to meet special conditions before it can evolve into a Magnezone, but the ability to catch a Magnezone is a rare feature in Pokémon Legends: Arceus.
When the Magnezone was introduced in Pokémon Diamond & Pearl, it became one of the first Pokémon to evolve based on location, similar to Leafeon and Glaceon's Mossy and Icy Rocks in various games. Since then, players have been able to earn Magnezones by leveling up Magnetons in magnetic fields, but the lack of obvious magnetism in Pokémon Legends: Arceus makes it difficult to find the right area.
Where to Catch Magnemite & Magneton in Arceus

While long-time fans may know how they get Magnezone in Pokémon Legends: Arceus, the fan-favorite Electric and Steel-type Pokémon has several oddities in the game that make it difficult to obtain. Strangely, while the Magnezone has a natural habitat in the Emerald Region, players cannot find Magnemite or Magneton in the wild on their own.
Instead, Magnemite and Magneton can only be found in the time warp of Pokémon Legends: Arceus, which happens to spawn in the Cobalt Coast region. However, even after players capture and evolve Magnemites or capture Magnetons, they cannot evolve Magnetons into Magnezones in Arceus until they reach Coronet Highlands.
How to Evolve Magneton to Magnezone in Arceus

While a Magneton can evolve into a Magnezone in the Sinnoh region by leveling up at Mt. Coronet, it can evolve in Coronet Highlands by simply being in the region in Pokémon Legends: Arceus or using a Thunder Stone. Once the player enters Crown Heights, Magnetons will have the ability to evolve into Magnezones, but no upgrades are required. This is similar to how Eevee evolved into Leafeon or Glaceon around the rocks of Mossy and Icy in the Hisui region, meaning players only need to see Magneton in their party to choose.
Where to Catch Magnezone in Arceus

Players can also simply catch the Magnezone in Legendary: Arceus by finding the Pokémon in Crown Row. If players head to the Celestic Trail, Clamberclaw Cliffs, or the mountain rims of Fabled Spring, they will be able to find flying Magnezones in each area About. As long as players have or can craft Shuttleballs, they'll be able to catch Electric and Steel-types that roam the sky, but in Pokémon Legends: Arceus, Wingballs or Jetballs will offer better odds of catching Magnezones.
