Cannot Create Celestial Exotic chest piece?
You cannot discover the celestial items, you need to purchase the recipe for the coat from the trading post.
If you hover over the recipe and it says you already know it, but it isn’t showing up, then that is a bug.
As khani said, you’ll have to buy the recipe for the armor piece you’re making.
Ah, okay I forgot this is one that needs unlocking. Thanks. You can disregard this thread.
