The World of Warcraft patch 7.1, Return to Karazhan, is now live! The patch is bringing back the iconic Karazhan, initially introduced as a ten-player raid instance in the Burning Crusade expansion, in the form of mythic five-man dungeon. The players will have to face eight bosses in Karazhan, on a mythic difficulty, so don't expect it to be easy.
The new patch also introduces a new raid, Trial of Valor, which has three bosses - Odyn, Guarm, and Helya. The raid itself will be available shortly after the launch of Patch 7.1.
The Patch 7.1 also brings new world quests, a new world event - Alcaz Isle, new battle pets inspired by Wrath of the Lich King raid bosses and much more.
There will also be another raid, The Nighthold, but it isn't available yet. Blizzard says it expected to be available early 2017 during Patch 7.1.
