A new wave of EX Raid invitations was just sent by the Pokemon Go company, and this time the EX Raid will go live on December 11.
As Niantic confirmed, EX Raid Battles are no longer a field test, they are officially confirmed. Also, they’ve shared the criteria on how a player is selected to participate in EX Raid, saying:
When the feature first entered field-testing, the system randomly selected a set of Trainers who were eligible for the EX Raid Battle. By taking Gym Badge level and total Raid Battles completed into account, we’re able to give Trainers who actively engage with the Gym where the EX Raid Battle is taking place and those who have invested more time into the Raid Battle feature a better chance of being invited to participate.
The new EX Raid is going live on December 11, for 45 minutes. Good luck!
