World of Warcraft Classic will return to the Wrath of the Lich King era on September 26th, Blizzard announced on Monday. WotLK is widely considered one of the best expansions in World of Warcraft’s nearly 20-year history. Even if subsequent releases went on to expand the game’s mechanics in more interesting and creative ways, few hit thematically in the way that WotLK did. For those who loved Warcraft III: The Frozen Throne, it felt special to set foot on the shores of Northrend for the first time and explore the continent from a new perspective, and then eventually fight Arthas as part of the Icecrown Citadel raid.

Ahead of the expansion’s arrival, Blizzard is introducing a new leveling mechanic called Joyous Journeys. Starting today, Burning Crusade Classic players can visit an innkeeper at one of their faction’s capital cities to toggle a 50 percent experience boost. You can use the boost to finish leveling an existing character or start working on a new one. The boost will be available until the launch of WotLK Classic. For those who want to create a Death Knight once the expansion arrives, you won’t need an existing level 55 character on a server to do so as was the case with the original release.

Blizzard will include Wrath of the Lich King Classic with all World of Warcraft subscriptions, meaning you won’t have to purchase the expansion separately if you want to bring your old guild back together.
