Shop Quest

After being recruited, Vanilla sets up a shop in the Pocket castle. This allows you to buy the merchandise of most item shops without having to navigate through the cities or villages. The shop's inventory starts with few virtually useless items, but the shop's stock grows steadily as you advance through this quest.

Her full inventory contains the following

This quest can be started as soon as Vanilla is recruited, but several seemingly unrelated actions need to be taken to finish it. These include the saving the merchant from Talus Hill, recruitment of Mini, curing the harpy epidemic and getting the healing seashell for the dark elf in Enrika. Vanilla needs to be in party when you're talking with her future trading partners.
