World of Warcraft patch 12.1, Curse of Ula'tek, is just around the corner, and there's plenty of new features on offer, including Lairs. World of Warcraft patch 12.1, Curse of Ula'tek, is set to launch in just a couple of weeks on Tuesday, August 11. Perhaps one of the most intriguing parts of the MMO's latest update is its addition of Lairs. A week after launch (so on the weekly reset, Tuesday, August 18), Midnight Season 2 will also launch. Curse of Ula'tek goes live in World of Warcraft on Tuesday, August 11.
