Bat wing

The wings of bats are comprised of a membrane with some degree of elasticity, aroung their flexible finger bones. Bat wings are also much thinner than the average wing of a bird.

Bat wings are an ingredient used in potion-making; they are a required ingredient of an Armadillo Bile Mixture (19 fl.oz. of bat wings for each 125 fl.oz. of potion).
