Wintergrasp is a World PvP zone, similar to Tol Barad. It emphasizes siege weapon warfare--walls and towers are destroyed not by player damage, but by siege damage. Your siege engine amount is controlled by which workshops in the zone your faction owns.

Every 2 hours 30 minutes, the battle for Wintergrasp begins. The defending faction must successfully defend for 30 minutes to keep it, while the opposing team attacks with siege weapons. Destroying towers both grants damage buffs and shortens the battle's time by 10 minutes. Between battles, elementals spawn that players from the winning faction can easily farm for crystallized elements. Players can also fight the bosses inside Vault of Archavon which are very simple and drop a variety of tier and PvP loot.

Players gain more honor based on the initial number of players they kill. Ranking up will also allow players to drive more elaborate siege vehicles: Siege Engines and Demolishers require the rank of First Lieutenant (10 kils).

Players need to queue for Wintergrasp via the battlematers at major cities, or by entering the zone. You must be level 75+. In addition, players can only enter at a 1:1 ratio, preventing imbalanced battles on lopsided faction realms.

There are a number of achievements associated with the zone, as well as PvP epics, heirlooms, and vanity mounts players can purchase from quartermasters.
