To evolve Sneasel, you need to fulfill certain conditions depending on the Pokémon game you're playing. Here's how to evolve Sneasel in different Pokémon games:
### Pokémon Games Before Generation IV (Diamond, Pearl, Platinum, HeartGold, SoulSilver, etc.)
In Pokémon games before Generation IV, Sneasel evolves when it levels up at night while holding a Razor Claw.
1. **Obtain a Razor Claw**: You can find a Razor Claw in various locations throughout the game, typically in caves, on routes, or by winning battles.
2. **Give Razor Claw to Sneasel**: Access your Bag and give the Razor Claw item to your Sneasel to hold.
3. **Level Up at Night**: Make sure it is nighttime in the game (usually between 8:00 PM and 4:00 AM in the game's internal clock). Then, level up Sneasel by gaining experience points through battles or by using Rare Candies.
4. **Evolution**: Once Sneasel levels up at night while holding the Razor Claw, it will evolve into Weavile.
### Pokémon Games From Generation IV Onward (Diamond, Pearl, Platinum, HeartGold, SoulSilver, Black, White, X, Y, Sun, Moon, Sword, Shield, etc.)
In Pokémon games from Generation IV onward, Sneasel evolves under different conditions:
1. **Level Up with Razor Claw at Night**: Similar to previous generations, you need to level up Sneasel at night. However, Sneasel does not need to hold a Razor Claw to evolve in these games.
2. **High Friendship (Daytime) in Pokémon Sword and Shield**: In Pokémon Sword and Shield, Sneasel evolves into Weavile when it levels up during the daytime while having high friendship with its trainer. There is no need for a Razor Claw in these games.
### How to Increase Friendship:
- Keep Sneasel in your party.
- Use it in battles.
- Give it vitamins or stat-raising items.
- Avoid letting it faint in battles.
- Use it in Pokémon Camp.
- Give it a Soothe Bell to hold.
By following these steps, you can evolve Sneasel into Weavile in various Pokémon games.
