I really want an Umbreon, but it just evolves into Espeon. What can I do to help it evolve into an Umbreon? And can it evolve into Umbreon?

You need to evolve eevee during the night not the day.

If that doesn't work the developer never mentioned anything to do with changing the evolution.
Good luck getting Umbreon... * It isn't that useful just a heads up. *

I know that it has to be night, but the game doesn't have night and day. But I tried to give it a moon stone to hold before it leveled up, and it worked
But thanks for help anyway

Hello!, Well, this pokemon is a Hack of Pokemon Ruby, so you can envolve Eevee to Espeon/Umbreon, to do it is simple:

-Make your eevee have maximum happiness, to have the maximum of happiness you need to play a lot with him, and walk a lot with him, one fast(but expensive) way, is trravel to groment City and buy proteins Iron Carbos HP UP, etc... This will make your pokemon happy without make him level up. To check the level of happiness you need to go to a city that a forget the name(plz someone help)

- Once you got him full happy, you just need to level up and he'll envolve... But then you say: There's no day and night!, but well, remember that on the start of the game your mom asked for you to adjust the clock? Well that clock says if is day or night... As i remember, hacks don't take the actuall time of where are u from on the game(as happen on game boy or DS) so you need to see it on your house...

Oh and other fast way is giving either the Moon or Sun stone to him...

I'm having a similar problem. My eevee is level 43 now and it loves me. It is holding a moon stone and my game clock says 8 PM but it still is always evolving into Espeon. I'm convinced that perhaps there is a problem with the time and you need to either try in the morning for an Umbreon, when you would usually get espeon, or you need to try it 12 hours after you catch the eevee, as if it has its own "internal clock."

EVERYONE LISTEN UP I KNOW HOW TO GET UMBREON. If you go to a dark place like one of the forest and get a level there you will get umbreon. Your welcome everyone

I FIGURED IT OUT! To get Umbreon, you must obviously have max happiness, but you have to level Eevee up in a dark place, I did it in Dardusk Forest, and I don't know if this is necessary but my Eevee was also holding a Moon Stone. My Eevee evolved to Umbreon at level 38, just an FYI. 

Yeah, I would suggest doing it in a dark place at night to try to get one. That is what I did to get mine and it worked. It is like level 60 now. Just do what you would normally do to get one in ruby since this is a hack of Pokémon ruby. After you get eevee, just level it up in a dark place of forest like nightagent said and you should get an umbreon. I hope that this helps.

I was informed that there is no happiness in this game...what Telia said, making it hold a moon stone is worth a try, and leveling it in a dark place like many people have already said is worth a try. 

Alright, I think this has been answered enough. Full happiness, level up a bit in dark areas, like Dardusk Forest. If it still won't work, I'll open this thread back up I guess.
