Bloodwing appears to be the remains of a dessicated bat that have been dipped in a pitch and preserved. The only features not covered with the black coating are the creature's gleaming eyes and razor-sharp fangs. Though it looks fragile the object is quite sturdy. Bloodwing has a wing span of approximately one foot. If examined for magical properties it radiates Superb alteration magic. A Great test of divination magic will reveal its enchantment.
To activate Bloodwing's powers the owner must sink its fangs into their own chest near the heart. Once attached the device (creature?) will drain blood from the owner equal to an Average wound, taking three rounds to do so. Once sated, Bloodwing will grant its owner Superb flight ability and Great echolocation ability for one hour. During this time Bloodwing remains attached, dropping free and becoming inert for three hours once the hour has passed.
