There is a Halloween-themed Special Research at the center of the first part ofPokemon GO’s Halloween Event 2022. This event-exclusive Special Research is dubbed “Mysterious Masks,” and it focuses on Yamask and Galarian Yamask. For those players that would like to learn more about the Mysterious Masks Special Research inPokemon GO, a complete list of its tasks and rewards can be found in this guide.
To note, while the first part ofPoGO’s Halloween Event 2022is set to conclude on October 27, players have until Tuesday, November 1 at 10am local time to claim Mysterious Masks. Players are advised to initiate and work on this Special Research sooner rather than later, though, as its tasks will be much easier to complete while the event is underway. This is primarily due to the fact that Ghost-type Pokemon will be appearing more frequently for Halloween, and those play a big role in Mysterious Masks.

As was previously alluded to, many of the tasks in the Mysterious Masks Special Research require players to engage with Ghost-type Pokemon, and fans will need to catch 120 of them before everything is said and done. While that is not a particularly difficult thing to do during the Halloween Event, the endeavor will become much more time-consuming when the spawn rates forGhost-type Pokemon inPoGOreturn to normal.
One final thing to mention is that the number 49 is a recurring theme in Mysterious Masks' tasks and rewards. This number is significant because Galarian Yamask must take at least 49 damage before it can be evolved inPokemon SwordandShield. While this fact does not affect the Special Research, beyond informing the quantities that appear in its tasks and rewards, it is one that somePokemon GOplayersmay find interesting.
