Hello, I'm an expert in the field of Pokémon knowledge. When it comes to Eevee and its evolution into Espeon, it's important to note that Eevee does not evolve into Espeon through leveling up in the traditional sense. Instead, Eevee evolves into Espeon when it levels up and meets a specific condition related to friendship and time of day.

Here's the step-by-step process:


1. Increase Friendship: You need to increase the friendship level between your Eevee and your character in the game.

2. Time of Day: Eevee must evolve during the day time to become Espeon.

To increase friendship, you can:
- Give Eevee berries or high friendship items.
- Avoid letting Eevee faint in battles.
- Use Eevee in battles and walk around with it to gain experience.

Once you've built up enough friendship, you can evolve Eevee into Espeon by leveling it up during the day.

Once you think that Eevee has reached 220, level it up during the day to get Espeon or at the night to get Umbreon. If Eevee doesn't evolve, it's Friendship is not high enough. You can use a Rare Candy or level Eevee up in a battle. Day time is 12:00 PM - 11:59 PM.read more >>
