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.

The Hangar will play host to iBUYPOWER Masters

iBUYPOWER Masters' eight teams will be spread into two GSL groups, with top two sides securing a place at IEM Oakland. First-placed teams will then battle it out in the grand final.

So far neither party has announced which teams will take part in iBUYPOWER Masters, but they're expected to be revealed soon.

The remaining eight teams for IEM Oakland, running from November 19-20, have already been released, with the list looking as follows:
