Eevee doesn't evolve into Umbreon via leveling up. Eevee doesnt evolve into any form that way actually. The eevee will need to gain a level at night, and your "friendship" will have to be high enough
it doesnt evolve by leveling up its by happiness at night
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 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
umbreon: lvl eevee 1 lvl up with happiness at late night (not rare candy doesnt work) espeon: lvl eevee 1 lvl up with happiness at day (not morning)
in the morning, after 8:00, you evolve eevee into espeon, at night, after 8:00, it evoles into umbreon (make sure eevee likes you alot)
friendship at night
You receive an umbreon from evolving eevee. You need to befriend eevee and then engage in a battle (at night on the game) and it should evolve into a umbreon.
Make Eevee as happy as you can. For Umbreon, level it up at night. For Espeon, level Eevee up in the day.
