The first downloadable content is a new area called the Palace of the Destitute. These ruins are filled with rare items and enemies more powerful than any you have encountered before. You can download this area for free.
Also available is Wilbell voll Erslied, the cute witch-in-training who first appeared in Atelier Ayesha. She comes back as an NPC in Atelier Escha & Logy, but as part of this DLC, she will join your party after you complete an event by talking to her in the urban areas of Corseit. The Wilbell DLC pack is available for 500 yen.
