I need some help. I got to level 70 goldsmith today. I worked on the quests and got to the level 70 quest Sultana Dreaming.

The problem I have is I can't find the receipt it is asking me to make, Gemworks Orchestrion. I've looked around to see if there is a new mastercraft book and I can not find any.

If anyone can tell me what I need to do would be very appreciated.

Thank you
