How to get the King's Rock in Pokemon Scarlet and Violet
There are three ways to get the King's Rock in Pokemon Scarlet and Violet, with there being no limit to how many you can get throughout your playthrough. You're first able to get your hands on a King's Rock after you've defeated four Gym Leaders. Once you've done so, you can purchase the item for 10k Pokedollars from the Delibird Presents store in Mesagoza.
The King's Rock can also be purchased from the auction house in Porto Marinada, where the vendors auction three randomly selected items a day. Players in search of a King's Rock and with a little more money in their wallet can make their way to the seaside town and prepare for a bidding war. If the King's Rock is not currently up for auction, players can change the date through the system settings on their Switch in order to reset the auctions.
For the more patient players, the final way of obtaining the King's Rock will not cost a single Pokedollar. Once you enter the postgame, you are asked by Geeta to challenge all of the Gym Leaders for a second time. Upon emerging victorious from all eight battles and speaking with Geeta for a second time, you will be rewarded with a King's Rock.
What does the King's Rock do in Pokemon Scarlet and Violet?
The King's Rock functions as both a battle and evolutionary item. When held by a Pokemon during a battle, their attacks gain a 10% chance to cause their opponent to flinch. This chance is affected by abilities such as Serene Grace, which is found on Paldean Pokemon such as Dundunsparce.
Outside of battle, the King's Rock will trigger evolution if held by a Slowpoke when it is traded. The Slowpoke will transform into Slowking, a Pokemon which can otherwise rarely be found in five- and six-star Tera Raids spread throughout the region. The King's Rock will also evolve a traded Poliwhirl into Politoed when held, though neither of these Pokemon are currently available in Scarlet and Violet.
