How To Get King’s Rock In Pokemon GO
It should come as a little surprise to Pokemon trainers on the prowl for evolution stones, but the King’s Rock evolution stone is found the same way as the rest of them.Players can get King’s Rock by spinning Pokestops,opening gifts, defeating Team Go Rocket Grunt leaders, and even through research rewards. However, their best bet is to spin Pokestops.
To increase one’s odds of finding a King’s Rock, it’s a good idea to hang out near areas with a high concentration of PokeStops. This may mean traveling to a bigger city, but taking the time to do this will make the search for a King’s Rock go much faster. Not only that, but players can advance their progress in other areas of the game while farming for King’s Rock at PokeStops. By far the most important feature players should keep in mind is that if playersspin Pokestops for seven days in a row, they will get a guaranteed evolutionary item, and that might as well be a King’s Rock.
At the time of writing, there are no Research rewards that award a King’s Rock inPokemon GO.
While walking between PokeStops,players can earn XPby catching new Pokemon and hatching eggs. Furthermore, they may acquire one of the other evolution stones in their attempt to get a King’s Rock, like the Up-Grade or theMetal Coat, which could go a long way in filling out the Pokedex. So, even though walking around between different PokeStops may seem boring, it’s actually a great way to advance inPokemon GO.
Who Can Evolve With King’s Rock In Pokemon GO?
Unlike theUp-Grade evolution item, there are two different Pokemon that can evolve with King’s Rock, and both of them are Water-type Pokemon — Slowpoke and Poliwhirl. Out of the two Pokemon that can evolve with King’s Rock, the easiest one is Slowpoke, so players may want to focus on evolving it first.
How To Evolve Slowpoke Into Slowking With King’s Rock
After acquiring the King’s Rock, the next step to evolving Slowpoke into Slowking is amassing50 Slowpoke candies. Players can earn Slowpoke candies in a variety of ways. Typically, they will get the most candy from hatching a Slowpoke from an egg, but that comes down to chance. They will also earn three Slowpoke candies every time a Slowpoke or Slowbro is caught, and an additional one for transferring duplicate Slowpokes and Slowbros to the professor. Yet another way to earn extra Slowpoke candy is byassigning it as a buddy Pokemonand walking around.
For those looking to catch Slowpoke/Slowbro — and Poliwag/Poliwhirl for that matter — the best place to look is near a body of water. As can be expected, Water-type Pokemon tend to spawn near public lakes and ponds, so if the weather permits, go for a stroll and start collecting as many of these Pokemon as possible.
How To Evolve Poliwhirl Into Politoed With King’s Rock
When it comes to evolving Poliwhirl into Politoed, players will want to spend a lot of time walking around lakes and catching Poliwags and Poliwhirls. For Poliwhirl to evolve into Politoed, players need to amass 100 Poliwag candies in addition to the King’s Rock, which is quite a tall order. It doesn’t help matters that players will need another 100 candies to evolve Poliwhirl into its other evolved form, Poliwrath. For thosefarming for Poliwag candies, the same methods used to earn Slowpoke candies still apply.
With enough persistence, players will earn enough candy and King’s Rock evolution stones to evolve Slowpoke into Slowking and Poliwhirl into Politoed. After adding these two rareWater-type Pokemonto their roster, players will be well on their way to catching all the Pokemon currently available inPokemon GO.
