never leafeon is NOT in the kanto pokedex anyways there is no national pokedex
Trade it to ruby,sapphire or emerald have them evolve your evee at night then give it back to leafgreen.
No, you cannot do so in LeafGreen. While Eevee can normally evolve into Espeon and Umbreon without stones, the lack of a time system in the game prevents Eevee from evolving into one of them.
so far, you cannot evolve eevee either to umbreon or espeon on FireRed because on FireRed and LeafGreen, there is no clock system. You must trade eevee to Emerald for evolving to Espeon or Umbreon
I believe that you have to get the eevee to max happiness ( or really high ) and level it up in the nighttime.
In ANY GAME!! If you use a moonstone, i think
Eevee doesn't evolve into Umbreon with a stone. Eevee evolves into Umbreon when it is levelled up with high happiness during the night.
Train your Eevee at night and with happiness. It will eventually evolve into Umbreon.
To make Eevee evolve into an Umbreon, you have to level it up with high happiness at night.
You will need to have your Eevee to full Happiness, then level it up at least once during the night to evolve it into Umbreon.
You cant the game has no way to keep time. You need to trade it over to ruby. saphire, or emerald witch all have time to evolve it. umbreon evolve's at night. espeon evolves at morning.
you have to raise eevee at night
Eevee doesn't have a set level to evolve into Umbreon. All you have to do to evolve it is max out its happiness at night. ~KKMG1
