If this item was added it shouldn't be available in the Mog Station. The shop should be for cosmetic items only.

That being said, I don't like this idea. I would rather see a slight buff to the rate at which leves recharge. However, I don't see any real problem with the rate at which you can level a crafter right now anyways. It's actually ridiculously fast.

When your leves run out, do collectibles.
