[quote name='Khalid']DLC#1: gives you the inventory item "Master's Secret Script" with the "Weapon Guard 2" skill and adds the story "Samii the Storyteller" as one of the dreams you can unlock in the game (to find this dream, look around in the pub in Uhra)[/quote]
This is correct (creating a Japanese silver account). Works perfectly fine, and gets you the preorder content without begging for codes.
