Question: what level does eevee evolve into umbreon pokemon y?
Answer: It took us around 10-12 levels for Eevee to gain full friendship and evolve. Remember, to get Umbreon, you have to level Eevee up after 8PM and before 4AM. Alternatively, Espeon is attained by leveling up Eevee after 4AM and before 8PM. Basically one needs to level up at night, while the other during the day.
