We've put together a comprehensive guide on how to evolve Sneasel into both Weavile and Sneasler in Pokemon Legends: Arceus.
Sneasel has been spotlighted as part of Pokemon Legends: Arceus with both a new regional form and a new evolution to go with it. Hisuian Sneasel now evolves into Sneasler, one of the noble Pokemon revered by the people of Hisui. According to legend, Sneasler has power bestowed upon her by the great deity Sinnoh, itself.
That doesn't mean that Weavile has been left out in the cold, however. Curiously, despite the new form, trainers can still gain access to the original form from the Johto region and evolve it into its previously revealed evolution. After all, while Sneasel might hail from Generation II, Weavile was introduced in Generation IV.
How to Evolve Sneasel into Weavile
Generation II's Sneasel, also known as Johtonian Sneasel, can only be found in Space-Time Distortions. It is a dark and ice-type. These Sneasel will evolve into Weavile when exposed to a Razor Claw evolutionary item during the night.
Known as the "Sharp Claw" Pokemon, this form of Sneasel is known for its spite and vindictive demeanor. It is described as "cunning and savage," using its sharp, hooked claws to tear into the most vulnerable part of its prey. It won't cease attacking until its opponent can no longer move. Laventon suggests that exposure to earth and water may impact this Pokemon's disposition. Its Hisuian PokeDex number is #202.
Weavile, on the other hand, is best known as the leader of its pack. This species will hunt as a group and employ increasingly complicated tactics. Laventon has theorized that evolution has actually make this Pokemon both stronger and smarter with this evidence. Its Hisuian PokeDex number is #204.
How to Evolve Sneasel into Sneasler
In contrast to its Generation II form, Hisuian Sneasel is more laid back and passive. As its full name suggests, this Pokemon can be found in the Hisui region. It is a fighting and poison-type. This variant will evolve into Sneasler when exposed to a Razor Claw during the day.
Hisuian Sneasel keeps both its "Sharp Claw" classification and PokeDex number. These Pokemon are also known for their sharp claws that are tipped with a unique venom that infiltrates its foe's nervous system. This variant may also be friendlier, overall.
Sneasler is known as the "Free Climb" Pokemon due to its ability to agilely scale mountains with ease. Its venomous claws and physical prowess tend to ward off other Pokemon that would normally be aggressive. For this reason it prefers solitude and does not form packs—unlike Weavile.
