From publisher blurb: Though it’s rare to find it in this day and age, connoisseurs of mystical goods will occasionally encounter a potion bearing this label: Burdened by a foe who turns your face to a scowl? Take revenge with this concoction most fowl. To the laymen, this will likely mean nothing. To the learned collector however, this “fowl” brew is one of the most prized potions in all the land. For this, dear friends, is the Potion of Duck. Imbued with potent powers of Polymorph, the Potion of Duck will transform any person or creature who drinks it into a helpless, feathered water bird. Their arms will turn to wings. Their mouth to a bill and, of course, their voice to a honking quack. The transformation is temporary. Even so, a single gulp is enough to transform even the mightiest of men into a duck for a space of six hours. And the more one drinks, the more powerful the effects.
