Ornaments

Ornament crafting isn't really a specific trade skill, but rather an NPC crafting skill that relies on Adventure skills. Ornament creation starts with the local Craftsman when you request to "Commission Ornament" from him. This in turn requires the proper Discovery Card in order for the Craftsman to start the commission. Once you request the commission, the Craftsman will require a substantial money deposit as well as the corresponding Discovery Card, which is removed from your inventory. Physical Discovery Cards are required, i.e., Statues or Wildlife. Port or Geographical discoveries are not valid.

There may be specific Discovery Cards that Craftsman will only work on, but this is just a theory at this time.
