Conjure Spud

You Conjure a Spud in your hand of around 5 to 10 ounces (0,31lbs - 0,61lbs / 140 -285 grams) of dubious quality. The spud can be used as a partial ration (1/4th) and spoils if uneaten after 1 hour.
Beware! As many spells of the cornucopia type the conjured spud does not have any Nutritional value, the spud cannot completely replace a balanced meal of hardtack and pemmican and many a mage, sorcerer or wizard has met his/her demise upon malnutrition relying on this spell. Druids appear to have no problems living on this spell because being one with nature apparantly absolves you of common nutritional understanding...
