Evolutionary items play a pivotal role in expanding your Pokédex in Pokémon GO, offering unique branch pathways for specific creatures. Among these special items, the King's Rock stands out as a key tool for evolving select Generation 1 Pokémon into powerful Generation 2 counterparts. Understanding which creatures require this item and how to effectively acquire it will help trainers complete their regional collections much faster.
Which Pokémon Can Use the King's Rock?
In Pokémon GO, the King's Rock is exclusively used to evolve two specific Pokémon: Poliwhirl and Slowpoke. When applied to Poliwhirl along with 100 Poliwag Candies, it transforms into the Water-type Politoed instead of Poliwrath. Similarly, using a King's Rock on Slowpoke alongside 50 Slowpoke Candies allows it to evolve into the majestic Slowking rather than Slowbro.
Choosing to use your King's Rock on these species provides an alternative evolution path that cannot be accessed through standard Candy alone. Both Politoed and Slowking bring distinct move sets and aesthetic value to your collection, making them valuable additions for collectors and battle enthusiasts alike.
How to Acquire a King's Rock in Pokémon GO
Obtaining a King's Rock relies mostly on daily engagement and continuous exploration throughout the game world. The most reliable method to secure one is by maintaining a 7-day PokéStop streak, which guarantees a random evolution item reward on the final day. Additionally, trainers can occasionally find a King's Rock as a rare drop from spinning standard PokéStops and Gyms.
Opening gifts sent by friends or completing specific Field and Special Research tasks also offers chances to earn evolution items. Keeping an active friend list and participating in seasonal events will significantly increase your overall odds of obtaining a King's Rock.
Best Strategies for Managing Evolution Items
Because evolution items take up valuable space in your item bag, managing your inventory effectively is crucial for smooth gameplay. Since only two Pokémon currently require a King's Rock, holding onto two or three copies is usually sufficient for most trainers. You can easily check your inventory and apply the item directly through the Pokémon summary screen when ready.
Planning your evolutions during special event bonuses, such as double evolution XP events, will maximize the benefits of using your hard-earned items. Prioritize evolving high-IV or shiny variants of Slowpoke and Poliwhirl to get the most value out of every King's Rock you consume.
