Sinistea

Sinistea (Japanese: ヤバチャ Yabacha) is a Ghost-type Pokémon introduced in Generation VIII.

It evolves into Polteageist when exposed to a Cracked Pot or a Chipped Pot. The item required depends on its form.

The Phony Form (if it lacks a mark of authenticity) requires a Cracked Pot to evolve.

The Antique Form (if it has a mark of authenticity) requires a Chipped Pot to evolve.
