For those enjoying the final notes of Battle for Azeroth or looking for something different to do in WoW Retail, the developers from Activision-Blizzard have released the official overview of the previously introduced feature that allows players to quest together regardless of levels: Party Sync.
When players activate Party Sync, everyone in the party becomes aligned to the same quest state and phase. By mousing over a quest in your tracker, you can see who’s on a given quest, what their progress is, and who’s ready to turn it in. You’ll also have access to a “replay quest” feature that allows players who have already completed certain quests to replay them with friends who haven’t for rewards that are appropriate to their current actual level, regardless of the original level of the quest. Quests can be replayed for rewards once a day.
With Party Sync, you can choose to have your level temporarily adjusted, making it so higher-level players can quest and experience outdoor content with lower-level friends as they level up.
