Sinistea is among the most intriguing Pokémon making a return in Pokémon Scarlet & Violet. Its appeal lies not in its stats or typing, but rather in its evolution process. Unlike most Pokémon that evolve through leveling up or using evolutionary stones, this Ghost-type Pokémon has a unique requirement of specific items for its evolution.
In order to facilitate the evolution of Sinistea into Polteageist, you will require either a Chipped Pot or a Cracked Pot, depending on the specific variant of Sinistea you possess. Initially, it may pose a challenge to discern the appropriate item needed, as it is not readily apparent which type of Sinistea you possess and which corresponding item is required for its evolution.
Revised as of October 15, 2023, by Gabrielle Castania: As the Teal Mask DLC has already been released and the Indigo Disc DLC is forthcoming for Pokémon Scarlet & Violet, we have taken the opportunity to revitalize our previous guides to cater to both new players venturing into Paldea and returning players seeking the DLC content. Within this guide, we will assist you in locating a genuine Sinistea and acquiring the Cracked Pot necessary for its evolution.
Where To Catch Sinistea

In Pokémon Scarlet & Violet, the presence of Sinistea is limited to a select few locations, with the highest likelihood of encountering it being in the far southwestern region of the map. In the accompanying map, you will observe this particular area clearly delineated as South Province (Area Six).
Within this locale, you will come across the town of Alfornada, which serves as the residence of the Psychic Gym. The town itself is situated on a section of level terrain, providing a conducive environment for the abundant spawning of numerous Pokémon in close proximity.
To encounter a Sinistea, simply explore the areas surrounding the town of Alfornada until these Pokémon start appearing.
Sinistea is not particularly elusive, so you should have no trouble locating one in this vicinity fairly quickly. It is advisable to conduct your search during daylight hours, as it appears that Sinistea is most frequently spotted during this time, especially in the form of the little teacup variant.
How To Find An Antique Form Sinistea

Sinistea manifests in two distinct forms: the Phony Form and the Antique Form. The sole disparity between these two lies in the presence of an authenticity stamp located on the bottom of the Pokémon, serving as the distinguishing factor.
The Antique Sinistea, which is the rarer of the two forms, will display a stamp on the bottom of its teacup. On the other hand, the significantly more prevalent Phony Sinistea lacks this distinguishing stamp.
Tips To Check For Sinistea Authenticity

Upon capturing your initial Sinistea, it will be registered in your Pokédex. It is probable that the Pokédex will initially exhibit the phony version of Sinistea. However, once you successfully capture an authentic Sinistea, the Pokédex will present you with the option to view its alternate form. This serves as an excellent means to verify whether you possess a genuine Sinistea within your collection.
The stamp of authenticity on Sinistea can also be observed while exploring the game world. This enables you to approach the Pokémon and adjust your camera angle to look upwards, providing a view of its bottom. While it may present some challenges, particularly if Sinistea is in motion, it is indeed possible to identify an authentic specimen using this method.
Finally, it is advisable to seek out Sinistea outbreaks. While the presence of authentic versions is not guaranteed, your chances of encountering one are enhanced when there is a higher overall frequency of Sinistea spawns in the area.
Authentic Sinistea Evolves With A Cracked Pot Instead Of A Chipped Pot

After capturing the desired form of Sinistea, the next step is to acquire the appropriate item for its evolution, as each form necessitates a different item. To evolve Phony Sinistea, a Cracked Pot is required, whereas evolving Antique Sinistea calls for a Chipped Pot.
Where To Get The Cracked Pot
The image above showcases the Cracked Pot.
To locate the Cracked Pot, proceed north of Casseroya Lake and position yourself to the left of the Groundblight Shrine. From the shrine, navigate towards the left, ascending the hill until you encounter a body of water. The Cracked Pot can be found on the ground near a small pond, adjacent to the cliff side.
Where To Get The Chipped Pot

The Chipped Pot can be easily found behind the houses in Porto Marinada, making it a relatively simpler task to locate.
Proceed by ascending the initial ramp starting from the Auction House, and make your way towards the rear of the houses. Underneath a sizable tree, you will discover the Chipped Pot.
Get More Cracked Pots And Chipped Pots At The Auction House
Regrettably, due to the absence of loot respawning over time, revisiting the aforementioned locations at a later time will not yield additional quantities of each item. However, there exists an alternative method to acquire more Cracked and Chipped Pots.
Within the Porto Marinada Auction House, there are three vendors situated in the center of the auction area. These vendors rotate their inventory on a daily basis. Each day, there is a one percent chance for each vendor to offer Cracked Pots or Chipped Pots for sale during their auctions, priced at 3,000 Pokedollars.

If your intention is to evolve multiple Sinistea into Polteageist, this particular method is the sole means of obtaining additional Pots, as the item is expended during the evolution process. It is advisable to ensure you have a substantial amount of cash readily available for when the bidding commences.
The items available at the Auction House undergo a daily reset, allowing you to visit multiple times in the hope of encountering the Pots. However, it is important to note that the auction encompasses a wide range of potential items, so it may require some patience before the Pots become available.
