you dont use a stone to evolve eevee into leafeon. You have to level it up near the mossy rock in eterna forest. so just use a rare candy when by it.
You don't need to use the stone, just level up eevee anywhere in the forest and it will evolve into Leafeon.
You do not need friendship to evolve Eevee into Leafeon. All you need to do is level Eevee in Eterna Forest.
I'm pretty sure you need to find a Leaf Stone.
To get a leafeon you need to get the eevee from bill in goldenrod city and level it in a grassy area
to get a leafeon in Pokemon platinum, you need to have an eevee and then at any lvl you have to use a leaf stone!
Eevee, can evolve into several types of Pokemon Leafeon, Glaceon, Vaporeon [ with a water stone], Jolteon [ with a thunder stone ], Flareon [ with a fire stone ], Espeon [ happiness full and leveled up during the morning ] and Umbreon [ happiness full and leveled up during night ] there is a stone where you have to evolve eevee near to get leafeon in i think eterna forest and there to get glaceon, you need to find a stone near snowpoint city eevee, by itself, isn't very helpful in my opinion.
you can't. there's no moss-stone to evolve it, so you'll need to trade it from diamond, pearl or platinum
You need to evolve Eevee near Mossy Rock in the Eterna Forest, which is in the Sinnoh Region.
in order to get a leafeon you will first need your eevee and then go into eterna forest and find the rock that is covered in moss. level your eevee up there and it will evolve into a leafeon :)
Eevee has 7 evolutions who are Vaporeon, Flareon, Jolteon, Umbreon, Espeon, Leafeon and Glaceon. To evolve Eevee into the water type Vaporeon, use a Water Stone on it however in order to evolve it into the fire type Flareon you need to use a Fire Stone on it and for the electric type Jolteon use a Thunder stone on it. Eevee will evolve into the dark type Umbreon if it's really happy and if you level it up at night and Eevee will evolve into the Psychic type Espeon if it's really happy and you level it up in the day time. For Leafeon, just level it up near the Moss Rock in Eterna Forest and it'll evolve into the grass type Leafeon and in order for Eevee to evolve into the ice type Glaceon you need to level it up near the Ice Rock which is near Snowpoint City.
You need an Eevee and level it up at Eterna Forest.
In Pokémon Conquest, in order to get Leafeon in it you will need to first recruit a wild Eevee which can be found in the Aurora, Pugilis, Valora, Vipera and Swams Kingdoms and then you will need to get your link level to at least 70% and you will need to accomplish something in the Greenleaf Kingdom and then your Eevee will evolve into Leafeon.
