Polteageist

Polteageist (Japanese: ポットデス Potdeath) is a Ghost-type Pokémon introduced in Generation VIII.

It evolves from Sinistea 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.
