Currently, Pokemon GO has plenty of Pokemon for trainers to catch in the wild. Evolving them, however, follows a different process than the console games. Most notably, any Pokemon that can only evolve by being traded while holding an item will require an evolution item on top of the required amount of Pokemon Candy.

The Johto region was the first to introduce evolving a Pokemon by trade while it was holding an item. Johto Evolution Items make up five of the current seven Evolution Items in Pokemon GO. Only certain Pokemon can use them, and getting these evolution items all comes down to luck.

How to Get Johto Evolution Items

There are a total of five Johto Evolution Items:

1. Metal Coat
2. Dragon Scale
3. King's Rock
4. Sun Stone
5. Up-Grade

In the mainline Pokemon games, trainers would have to give one of these items to their Pokemon before initiating a trade. Once their Pokemon reached another trainer, an evolution would occur and consume the item. Trading does exist in Pokemon GO, but it seems GO abandons the trade-evolution requirement to make it easier for players to evolve their Pokemon without relying on someone else.

Except for the Sun Stone, Johto Evolution Items are used on a Pokemon to evolve them into a Johto Pokemon. For example, Seadra needs a Dragon Scale if it's to evolve into Kingdra. Given that these are difficult items to come by, Johto Evolution Items aren't readily available at the in-game Shop. If players want an Evolution Item, they'll have to try their luck at PokeStops.

Unlike Ultra Balls or Super Potions, players don't need to be at a specific level to get an Evolution Item. The drawback here is that the drop rate of an Evolution Item is at a meager 1%. This means if players are looking for a specific Evolution Item, they may be spinning more than a few PokeStops until they get the item that they want. If players are lucky, they'll get the item much sooner.

Spinning a PokeStop is easy. Players simply need to get close enough to the PokeStop until the blue cube on the overworld map turns into a blue PokeBall. They can then tap the icon and slide/spin the disc. PokeStops can drop 3-9 items depending on a player's luck. Players can also spin Pokemon Gyms. The method is the same as a regular PokeStop, only players will need to tap the icon in the bottom-right corner to access the Gym's disc. It's worth noting that even if the Gym isn't the same color as the player's team, they can still receive items.

Each PokeStop/Gym has a cooldown period of 5 minutes. The overworld map will display a "spun" Stop/Gym as a purple PokeBall symbol. With this in mind, it's entirely possible for players to just camp at one PokeStop or Gym and keep spinning the disc until they get the Evolution Item that they need.

Thanks to the "Spin of the Day" mechanic, players that spin PokeStops seven days in a row will receive over 15 items on their seventh day. If players miss one day, then the PokeStop Streak will be broken and they'll have to start over. Since there's a guaranteed Evolution Item on the last day of the streak, players should take advantage of this feature whenever they can.

Evolving Pokemon with Johto Evolution Items

Simply getting the Evolution Item isn't enough. As most Pokemon GO players will already know at this point, most of the Pokemon can only evolve if they are fed Candy. This means that in addition to the Evolution Item, players will need a set amount of Candy for their Pokemon.

The best way to get Candy is to use Pinap Berries when catching Pokemon or walking with a Buddy Pokemon. There are also Rare Candies, which, when fed to a Pokemon, will convert the Rare Candy into a Pokemon-specific Candy. Transferring a Pokemon also guarantees one piece of Candy, but this method isn't recommended unless players have multiples of the same Pokemon.

The Pokemon that can evolve via Johto Evolution Items are quite rare, but players can obtain them through one or more of the following methods:

1. Hatch Eggs gained from Adventure Sync rewards and PokeStops. The 2km, 5km, and 10km Eggs can be received from a PokeStop/Gym. 12km Eggs can only be gained from defeating Team Rocket Leaders.
2. There are also Timed and Special Research Tasks that may have one of the Pokemon as an Encounter reward. Unfortunately, most of these have already passed, such as the Decoding Porygon Special Research.
3. Catch them in the wild. Knowing a Pokemon's type will make it easier to know which habitats they'll most likely be found in. Water-type such as Poliwag/Poliwirl and Horsea are easier to find near bodies of water such as lakes or rivers.
