Next question: Nashmau earring. Can I craft the item for my friend? I tried tonight, and only the person who has claim can deposit ingredients. He hasn't done the synergy quest yet, so he couldn't claim the furnace. However, if he does the quest, can he trade the earring ingredients, but I actually operate the furnace, since my synergy is 56 and his is zero? Or does the person trading have to operate furnace too?
