After a bit of a delay to ensure that everyone starts on the same footing, World of Warcraft's Mythic Keystone dungeons and Uldir raid have finally became available last week. If you've already managed to complete both the normal and heroic difficulty settings, you'll be glad to hear that the mythic version of the Uldir raid is now live as well. As is tradition, the mythic version has quite a few bugs you'll need to contend with, so unless you're racing to become the world first I would highly suggest waiting for a couple of days.

On the other hand, if you don't feel like spending hours upon hours attempting to beat a single boss and just want to experience what the new raid is all about, you might want to check out the newly released Raid Finder difficulty. Only the first couple of bosses are currently available for it, but they should still give you a pretty solid impression of what Blizzard is attempting to do with Uldir. 

As for the rest of the bosses, they will be unlocked in the two following weeks. On September 25th you'll be able to square off against the Fetid Devourer, Vectis and Zul, while October 9th will bring with it the two main bad guys: Mythrax the Unraveler and G'huun. If you have no idea who those two even are, I would highly recommend you play through the Horde storyline before diving into Uldir. It'll give you some much needed context for most of the boss fights.

You can learn a little bit more about Uldir and the bosses currently available by visiting the official website. Good luck with the loot!
