Onix is one of the Pokémon from the original games, and yous'll be able to catch it in Pokémon Legends: Arceus. It's a massive Stone and Footing-type Pokémon, and if you're looking for a powerful Stone and Footing-type added to your team, we highly recommend it. But we also remember you should evolve information technology into Steelix, its second grade. To do this, y'all'll need a specific item to evolve it. In this guide, we'll encompass how to evolve Onix into Steelix in Pokémon Legends: Arceus.

The only way to evolve Onix into Steelix is if you give it Metal Coat. Metallic Glaze is a evolution item that you tin acquire in the game. At that place are several ways to become information technology, but the best way to get Metal Coat is to head over to the Trading Outpost and speak with Simona. She'll offer to sell you several items there, such every bit the Metal Coat for Merit Points. Yous can earn Merit Points by collecting lost Satchels you find in your games. These vest to players, and they lost them when they fainted with a Pokémon attacking them while exploring Hisui.

The other style to earn a Metal Coat is to have a Ursaluna seek information technology out as a treasure or notice one during a space-time distortion. Unfortunately, both of these methods are random.

Once you have the Metal Glaze, all you accept to practise is give it Onix, and it will evolve into Steelix.
