How Yamask Timed Research works in Pokémon Go

Yamask Timed Research was released on Thursday, 20th October as part of the Halloween 2022 celebrations and, since it's a timed research quest, you only have until Tuesday, 1st November at 10am (local time) to buy and complete the quest, or you won't gain access to it before it disappears for good!

The Yamask Timed Research quest costs £0.79/$1, or the equivalent pricing tier in your local currency, but can't be purchased with Poké Coins, so you'll have to spend real money if you want access to all these Yamask encounters.

This quest is entirely about the ghost-type, Yamask, which was originally a human being. Due to its transformation, Yamask actually retains the memories of its human life and the mask it holds resembles its face from this time. If someone were to wear this mask, they would grant Yamask the ability to possess their body.

Good luck completing the Yamask Timed Research in Pokémon Go!
