With the HCT Summer Championships almost over, Blizzard has torn the veil off the format of the Hearthstone World Championship at BlizzCon in November.

While the main event will run Nov. 4-5, the group stage will take place during the BlizzCon Opening Week between Oct. 26 and 30. There will be four groups with four players each, one from each HCT region: Americas, Asia-Pacific, Europe and China. Seeding will be based on HCT points.

While the group stage will have a double-elimination, bracket with two players from each group advancing to the quarterfinals, the main event at BlizzCon will be single-elimination. Since HCT events use Conquest format, each match will be best-of-seven and each player will have five decks and one ban available to them.

The tournament's quarterfinals will be played on Nov. 4 while the semifinals and Grand Final will take place the day after on Nov. 5. All 16 players will get a cut of the $1 million prize pool, with $250,000 going to the eventual world champion.

Qualified players include William "Amnesiac" Barton, Julien "Cydonia" Perrault-Harvey, Sanghyeon "DDaHyoNi" Baek, Ole "Naiman" Batyrbekov, Yuxiang "Breath" Chen, Il-Mook "handsomeguy" Kang, Thijs "Thijs" Molendijk, Zhou "JasonZhou" Bin and Edwin "HOTMeowth" Cook.

More will fill those ranks with the HCT European Summer Championship taking place this weekend, Sept. 24-25 and the Asia-Pacific Summer Championship following on its heels Sept. 30-Oct. 1. The Last Call Invitational qualifiers will run Oct. 3-Oct. 15 to determine the final four BlizzCon slots.
