Nutriment (Proficiency)

A body with this proficiency can draw sustenance and nourishment from ethereal mists with a successful proficiency check. Nutriment is a more complex, conscious application of the same principle by which travelers on the Ethereal Plane breathe. When a character successfully uses this proficiency, she converts enough of the possibility found in the ethereal mists into base nutrients for the equivalent of one meal.
A body who uses this proficiency doesn't create gourmet food. Fact is, the nutrition is bland and unsatisfying. For every three uses in a row, a body suffers a -1 penalty to the check. Thus, a cutter who skipped nine real meals and used the nutriment proficiency instead suffers a -3 penalty to her proficiency check.
