How to evolve Eevee into Glaceon in Pokemon Scarlet

Actually, I evolved my Eevee into Glaceon during my own playthrough, and it's really straightforward! All you need is an Ice Stone, which you can easily find if you explore enough or check out the Delibird Presents store in any of the bigger towns. I found my Ice Stone while trekking near Glaseado Mountain. Once you have it, just use it from your bag on Eevee, and you'll get Glaceon.

To evolve Eevee into Glaceon in Pokemon Scarlet, you gotta expose your Eevee to an Ice Stone. You can find these shiny stones scattered around the Paldea region, or hit up the local Delibird Presents shops in-game. Just navigate to your bag, select the Ice Stone, and use it on Eevee. Bam! You'll have yourself a cool Glaceon in no time!

Ice Stone's the key. Don't overcomplicate it. :)
