Fire Stone

A Fire Stone is one of the evolution stones. It is used to evolve several Fire-type Pokémon:

• Vulpix→Ninetales
• Growlithe→Arcanine
• Eevee→Flareon

Fire Stones are also needed to craft orbs of fiery souls, Fire Gems, Fire Stone tools, and Fire Stone armor.

Fire Stones can be obtained by crafting or as a tier 2 special drop

Crafting

A Fire Stone is crafted with nine Fire Stone shards. They are dropped from Fire Stone ore, found anywhere near lava. Fire Stone shards can also be obtained by using Forage on lava with a Fire-type Pokémon.
