Patch 1.13.3

Patch 1.13.3 is the battlegrounds patch for World of Warcraft: Classic that released on December 10, 2019.

Battlegrounds
The fields of battle are open, and the Alliance and Horde are set to clash over Warsong Gulch and Alterac Valley.

Warsong Gulch is a 10v10 game of capture-the-flag, with each faction attempting to carry their opponents' flag all the way back to their own base, while preventing the opposition from doing the same. Players fight in level-ranges in Warsong Gulch: 10-19, 20-29, 30-39, 40-49, 50-59, and level 60.

Alterac Valley is a large 40v40 tug-of-war zone, with many quests, objectives, and areas of interest. All players at level 51 and higher are placed into a single level-range in this epic struggle, with rewards via reputation as well as quest rewards. Some Alterac Valley rewards are highly sought, such as Don Julio's Band, Lei of the Lifegiver, and Ice Threaded Arrows/Bullets.

The Alliance entrance to Warsong Gulch is in Silverwing Grove in Ashenvale Forest, and the Horde entrance is near Mor'shan Base Camp in the northern Barrens. The Alliance and Horde entrances to Alterac Valley are in northern Hillsbrad Foothills. Both Warsong Gulch and Alterac Valley can also be entered by speaking with the appropriate battlemaster in your capital city.

Battlegrounds are cross-realm, which means you'll fight alongside allies and against opponents from all of the realms in your region.

Elemental Invasions
Across Kalimdor, Blazing, Thundering, Watery, and Whirling Invaders now occasionally appear in Un'goro Crater, Azshara, Winterspring, and Silithus respectively. The elementals appear to be seeing just how far into these territories they can penetrate before being beaten back by the forces of the Horde or the Alliance.

Keyring
The key button in your micro menu now opens your Keyring, an additional bag for keys only, that scales up to hold up to 12 keys.
