ESL have revealed a partnership with iBUYPOWER, whose $100,000 Masters event taking place from November 12-13 will serve as an offline qualifier for IEM Oakland.

Eight teams will be featured at iBUYPOWER Masters, which will take place at The Hangar located at Orange County fairgrounds in Costa Mesa, California.

The event will be run in partnership with ESL and will serve as an offline qualifier for the following weekend's IEM Oakland, as there will also be four spots up for grabs for the 12-team, $300,000 event.
