EX Raid Pass

An EX Raid Pass, previously Exclusive Raid Pass, is a special event Raid Pass used to participate in an EX Raid Battle.

Details
The method for obtaining one is currently unknown because this feature is undergoing beta-tested. Select Trainers will receive an EX Raid Pass via their Journal. When the user clicks on the item in the journal, an invitation will be presented and provide information as to when and where the the EX Raid Battle will occur.

Many reports indicate that the chosen Gym will be one that has been recently raided by the Trainer in the past couple of days.
