While we're trying to flesh out our Pokedexes in Pokemon GO, now is a great time to make sure that we're evolving all the critters that we've collected. Let's take a bit of a trip down to memory lane, away from the Battle League and Pokemon Sword and Shield madness, and all the way back to some vintage critters. Some Pokemon require items to evolve in Pokemon GO, just like the mainline games, so we're happy to present our King's Rock Pokemon GO guide for those wondering what this item does and how to get it.

King's Rock Pokemon GO - What Does The Item Do 

So, you're wanting to know what a King's Rock is good for. Lucky for you, we've got the goss. You might remember it from some of the mainline games, though it serves a slightly different purpose in Pokemon GO. The King's Rock would occasionally causing opponents to flinch in battle when faced with the Pokemon holding it, but that particular perk doesn't apply here. In Pokemon GO, it's strictly for evolution use only, though that in itself isn't really anything new. If you have the King's Rock, you will be able to use it to evolve the following Pokemon:

  • Poliwhirl into Politoed
  • Slowpoke into Slowking

The key to evolving Poliwhirl and Slowpoke in Pokemon GO is to use the King's Rock on either of them, and also some candy, just as you normally would when trying to evolve any other Pokemon. To evolve a Poliwhirl, you're going to need 100 Poliwag candy. To evolve a Slowpoke, you're going to need 50 Slowpoke candy. As we've mentioned previously, it really isn't all that difficult. The hardest part is probably getting your actual hands on a King's Rock. 

To get a King's Rock in-game when it comes to Pokemon GO, you're going to have to be at least Level 10. You'll get it from spinning PokeStops and taking on Gyms, but these are pretty hard to come by. Just like most evolutionary or use items in Pokemon GO, a King's Rock is considered rare, so don't get too discouraged if it takes you time to find one. You just need to have patience.

Now that you know what the King's Rock Pokemon GO item does, and how you can use it, you'll be able to get the Slowking and the Politoed of your dreams. Sure, it's all about spinning PokeStops and cracking on to Gyms, but with enough persistence, we reckon you'll get your hands on one eventually.
