The Siege of Neverwinter is set to run from August 13 at 10a PDT through September 3 at 10a PDT and will feature activities and rewards galore.
There look to be a few activities highlighted including Cult Invasion, Counter Attack, and Dragon Attack. For example, Dragon Attack is described as,
“The Cult of the Dragon believes that they have a few scaley aces up their purple sleeves: dragons. Unfortunately for them, the city of Neverwinter has you. Clash with the dragons outside the city walls and forge your legacy in blood and fire!”
Throughout the event, you’ll be able to earn Dragon Hoard Coins, Dragon Hoard Coffers, and other items. You can also earn Writs of Commendations which can be earned daily via daily quests. Dragon Cult Insignias can be earned by participating in Heroic Encounters.
Rewards for the siege include the Siegebreaker Griffon mount, Neverwinter Siegebreaker Charger, a battle horn, banner, and more. The event also features several fashion options such as dye packs. You can read all about the Siege of Neverwinter and the item details here.
