There are two sets of weekly quests in Wintergrasp. They are obtained from quest NPCs in Wintergrasp Keep for the defending faction; the attacking faction's quest NPCs are at the site of the incoming portal from Dalaran. When a battle for control of Wintergrasp Keep begins, the quest NPCs despawn. The quests can be completed over multiple battles for control of Wintergrasp Keep. They can be completed while part of a raid group. As of patch 3.1.2 All Lake Wintergrasp daily quests have been changed to a weekly format.
