“What Lies Beneath the Mask” exists alongside the Pokémon Go Halloween event
Yamask and other ghost-type Pokémon are the focus of the new Special Research Task set. All of the procedures and rewards are detailed in our Pokémon Go “What Lies Beneath the Mask” guide.
You can perform the Special Research at any moment after checking in and obtaining it. Because the Special Research necessitates acquiring a large number of ghost-type Pokémon, it’s preferable to attempt it during the Halloween-themed events, when spawning are increased. It will be considerably more difficult to accomplish after the event has ended.
