It’s hard to believe World of Warcraft has been out for two decades, but here we are. To celebrate WoW’s 20th anniversary, Blizzard is running a special event in November and December, and it’s a blast from the past.

The 20th-anniversary event brings back Blackrock Depths as a raid, adds WoW Classic timewalking dungeons, introduces new World Bosses in Tanaris, and, best of all, adds a transmog set for every class based on the famous tier 2 armor sets from Blackwing Lair. Classes that didn’t exist during WoW Classic, like Death Knights, Monks, Demon Hunters, and Evokers, all get new sets based on old themes.
