you dont need a stone you need to level it up in eterna forest
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 can evolve evee to leafeon by taking leafeon to a stone in the forest by the second gym leader.
To evolve your Evee into Leafeon, get a leaf stone, and use it on Evee, and it will evolve into Leafeon! Have fun with Leafeon! -Garrett
use a leaf stone
I'm pretty sure you need to find a Leaf Stone.
eve to leafeon
leaf stone
It is called a "leaf stone"
You don't need to use the stone, just level up eevee anywhere in the forest and it will evolve into Leafeon.
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!
you can't. there's no moss-stone to evolve it, so you'll need to trade it from diamond, pearl or platinum
Eevee - Leafeon Gloom - Vileplume Weepinbell - Victorybell Exeggcute - Exeeggutor Nuzleaf - Shiftry I think that's all Evee doesn't evolve with a leaf stone there is a special stone somewhere and you need to be near that stone with the evee and battle with it until it likes you then level it up again and its leafeon.
