We've explained all the Pokemon that evolve using a Leaf Stone in Pokemon Legends: Arceus.
It's no surprise that the Leaf Stone has made a reappearance in Pokemon Legends: Arceus. This Item has been around since Generation I and has only gained popularity over time, being used to evolve the likes of Gloom, Weepinbell, Exeggcute, and Nuzleaf. It has an "unmistakable" leaf pattern from which the stone gets its name.
More information on how to obtain a Leaf Stone can be found in our Evolutionary Item guide for the game.
All Pokemon That Evolve Using a Leaf Stone
At the time of writing, the only Pokemon that evolves using a Leaf Stone in Pokemon Legends: Arceus is Eevee.
When exposed to a Leaf Stone, Eevee evolves into Leafeon. Like its other possible evolutions, Leafeon is pure in its typing—making it exclusively a grass-type.
Leafeon, the "Verdant" Pokemon, has a molecule structure closer to that of a plant than an animal. Its primary asset is its tail, which is said to be as sharp as a master-crafted sword and strong enough to fell a tree. Its Hisuian PokeDex number is #031.
However, trainers don't necessarily need a Leaf Stone to evolve their Eevee into a Leafeon. They can actually do this without the item, entirely, by bringing the Eevee to a special location. Within The Heartwood, inside the Obsidian Fieldlands, trainers can find the Mossy Rock. Simply bringing Eevee to visit the rock will prompt its evolution into Leafeon.
More information on Eevee and how to obtain all its evolutions in Pokemon Legends: Arceus can be found in our Hisui Eevee guide. For all other evolution inquiries, make sure to check out our guide for evolving Pokemon in Pokemon Legends: Arceus.
