Update 13: Web of Chaos has a generous portion of goodies for all players in the form of three new free quests. These quests include tackling a uppity cult, freeing a prisoner from captivity, and battling the nefarious Spinner of Shadows itself.
Also coming with DDO's next update will be a few additional store options, cosmetic pets, and the ability to unlock level 7 veteran status. The latter acquisition will allow you to make a new level 7 adventurer right out of the gate and can either be purchased with real money or in-game favor.
You can read up on Update 13 and the expansion pack in our recent interview with Turbine.
