You can get to the Challenger League by participating in open qualifiers which will be happening in Europe, North America and Latin America. There will be two open tournaments per region and the best two teams of each qualify for the next season of CL and will be competing for Pro League then.
Qualifier #1 will be taking place on August 6th, while Qualifier #2 is scheduled for August 13th, and, what’s worth mentioning, teams that are dropping from this season of the CL can also participate in the open qualifiers!
Bear in mind, that during those two weeks Go4s will be ran on Saturday instead of Sunday.
