"Pokémon: Let's Go" Stone Evolution Guide
In Pokémon: Let's Go, there are many Pokémon that require using a special type of stone to evolve, 18 final evolutions to be exact. For example, you'll need a Moon Stone to evolve a Nidorino to a Nidoking. For those of you looking to fill your Pokédex, you'll need to get quite a few stones of various types. They can be both tricky or expensive to get, so I'll cover which ones you need and how to get them.
Using an Evolution Stone
Using an Evolution Stone is fairly simple, you just need to:
- Put the Pokémon you wish to evolve into your party
- Navigate to your bag
- Go into your "Power-Up Pocket"
- Select the stone you wish to use
- Select "Use this item"
- Select the appropriate Pokemon to evolve
Don't worry it won't let you accidentally use a stone on the wrong Pokémon.
Getting a Moon Stone is mildly annoying, but it certainly isn't difficult. You're going to need four of them in total.
You can a Moon Stone in Mt. Moon, hidden in the craters you'll see scattered around. You won't be able to see it, so just run up to a crater and see if you can pick up anything. Your buddy should give you a heads up as their tail will start to shake as you get close to a hidden item. It does periodically respawn, once every 24 hours, so you'll need to revisit a handful of times in order to get all 4 stones required to fill up your Pokédex.
It isn't entirely clear if Moon Stones have an equal chance to be at any crater, but I personally found two in one location (see screenshot below). This location is a few ladders down from the beginning of Mt. Moon and is not directly on the normal path.
Moon Stone Evolutions
The Moon Stone is used to evolve four Pokémon into their final forms.
- Nidorino to Nidoking
- Nidorina to Nidoqueen
- Clefairy to Clefable
- Jigglypuff to Wigglypuff
Leaf, Fire, Thunder, Ice, and Water Stones
Fortunately, these stones are much easier to come by. In order to get a Leaf, Fire, Thunder, Ice, or Water Stone simply go to the giant department store in Celadon City. It's the giant 2-door, 5 story building on the west side of town close to route 16. Take the elevator to the 4th floor "Wiseman Gifts". Talk to the clerk on the right side and you can buy any of the stones for 5,000 Pokédollars.
Of course, you can find various stones scattered around the game. However, at 5,000 each, the price is cheap enough not to worry about it. It's likely the better choice to just go buy the stones rather than hunt them down.
Leaf Stone Evolutions
The Leaf Stone is used to create three final evolutions:
- Gloom to Vileplume
- Weepingbell to Victreebel
- Exeggcute to Exeggutor
Fire Stone Evolutions
The Fire Stone is used to create three final evolutions:
- Eevee to Flareon
- Vulpix to Ninetails
- Growlithe to Arcanine
Thunder Stone Evolutions
The Thunder Stone is used to create just two final evolutions:
- Pikachu to Raichu
- Eevee to Jolteon
Just remember that you can't evolve your main partner Pokémon, and will have to use wild-caught Eevees and Pikachus.
Ice Stone Evolutions
The Ice Stone can be used to make two evolutions, but they are both Alolan forms, so they're not necessary for your Pokédex.
- Alolan Vulpix to Alolan Ninetails
- Alolan Sandshrew to Alolan Sandslash
Water Stone Evolutions
The Water Stone can be used to make four final evolutions:
- Poliwhirl to Poliwrath
- Eevee to Vaporeon
- Shellder to Cloyster
- Staryu to Starmie
You can pretty easily make a lot of progress on your Pokédex so long as you've been grabbing various types of Pokémon along the way. Many times all you need to do is just use a stone on one of them and you don't even have to level it up through a 2nd evolution. In many cases, you can also just catch the 2nd evolution. Overall, a quick pit stop with some money in the Celadon Department Store is going to be a bit step forward on your collection.
The Moon Stone, on the other hand, can be a bit annoying. It may be easier for you to find those Pokémon in the wild to catch, trade for them, or transfer them from Pokémon Go, depending on your appetite for searching through a low-level area for multiple days.
