Question: how to get eevee to evolve into umbreon in pokemon black 2?
Answer: In order to get Eevee to evolve into either Espeon or Umbreon, you'll need to raise its Friendship level to at least 220. A common way to increase Friendship is to just keep Eevee in your party as you walk around. You'll gain 1 Friendship every 512 steps you take in the game. Give Eevee a haircut.
