I'm trying to find a Fire Stone before the Elite Four so I can evolve my Growlithe.
I'm aware that you can get one in the Pokeathlon, but I apparently need the National Dex for the last six items, and I have to beat the Elite Four to get the National Dex. I'm also aware there are a few ways to get one in the Kanto region, but I have to beat the E4 to get full access to that region.
Are there any ways to get the stone in Johto before beating the Elite Four? I love my Growlithe, but he's not quite the powerhouse fire-type I'm looking to use against the Elite Four. I can always swap him out for Ho-Oh, but I'd prefer an Arcanine to that.
