AverageUnknown is incorrect. There are some [nourishments][1] that are account-bound, and [Nomad's/Sinister][2] stats don't drop out of any ascended boxes.

**Example nourishments:**

[Bountiful Tuning Crystal][3]

[Furious Tuning Crystal][4]

The Bountiful/Furious set applies to sharpening stones and oils as well. I know there are a few foods out there that are account-bound. Note that reaching 400 in a crafting discipline is worth 40 achievement points, and 500 is worth an additional 25. Reaching 400 can cost you around 10-15g per discipline, 500 considerably more. There's a good chance we'll see more of these in HoT and beyond, so I recommend going for at least 450 if you're looking for things to do.
