In Pokemon Legends: Arceus, you can find both Sneasel as well as Hisuian Sneasel, who evolve into Weavile and Sneasler, respectively.
If you want to know how you can get both of these fantastic evolutions, then this is just the guide for you; read on ahead!
How to Find Sneasel and Evolve it into Weavile in Pokemon Legends: Arceus
In order to get Weavile, you will need to catch a regular Sneasel, which can be found only after beating Noble Kleavor in Obsidian Fieldlands, since this event triggers the appearance of Space-Time Distortions, where you will find Sneasel.
Sneasel are a rare encounter in Space-Time Distortions, but are more commonly found in ones that appear in Obsidian Fieldlands. You are quite likely to run into many other Pokemon as well, however, so you will need to lure the other Pokemon away before you can try and snag your Sneasel with a Great or Ultra Ball.
Once you get a Sneasel, you need to get a Razor Claw and use it on your Sneasel during the nighttime to evolve it into a Weavile.
Razor Claws can be rarely found by defeating Sneasel and obtaining it as a drop. Fortunately, you can also buy them from the Trading Post in Jubilife City for 1,400 Merit Points.
How to Find Hisuian Sneasel and Evolve it into Sneasler in Pokemon Legends Arceus
Hisuian Sneasel can be found in two locations: Coronet Highlands (Celestica Trail and Primeval Grotto) and Alabaster Icelands (Avalugg’s Legacy and Glacier Terrace).
Once you’ve caught a Hisuian Sneasel for yourself, you simply need to use a Razor Claw on it during the day to evolve it into Sneasler.
