To evolve Eevee into Umbreon, the method depends on the game you are playing, but here are the main ways:
In Pokémon GO
- Set Eevee as your buddy Pokémon and walk at least 10 kilometers with it, earning 2 Eevee candies.
- Then evolve Eevee during the night while it is still your buddy.
- Evolving at night will yield Umbreon; evolving during the day will yield Espeon.
- Alternatively, you can use the nickname trick by renaming your Eevee to "Tamao" before evolving it once to get Umbreon.
- Make sure the Eevee evolution icon shows Umbreon’s silhouette before evolving; if not, try walking more or restarting the game
In main series Pokémon games (e.g., X/Y, Scarlet/Violet)
- Increase Eevee’s friendship (happiness) to a high level (around 220 pre-Sword & Shield or 160 post-Sword & Shield).
- You can raise friendship by walking with Eevee, feeding it vitamins, getting massages, battling without fainting, or holding a Soothe Bell.
- Once friendship is maxed, level up Eevee during the night (roughly between 8 PM and 4 AM in-game time).
- Eevee will evolve into Umbreon if leveled up at night with high friendship.
- Avoid Eevee knowing any Fairy-type moves (like Baby-Doll Eyes) to prevent evolving into Sylveon.
- If evolved during the day with high friendship, Eevee evolves into Espeon instead
In summary, for Pokémon GO, walk 10 km with Eevee as your buddy and evolve it at night. For main series games, maximize friendship and level up Eevee at night without Fairy moves to get Umbreon.
