Harpy

A harpy looks like a giant vulture bearing the torso and face of a human female. They are able to attack with their claws as well as with a normal weapon, but they are most feared for the power of their song by which they are able to charm living creatures, and, having charmed them, tear them to pieces at their leisure. All living creatures within a 300' range of one or more singing harpies must make a save vs. Spells or become charmed. The same harpy’s song cannot affect a creature that successfully saves again for 24 hours. This charm is very powerful, such that a victim will approach the harpy or harpies without fear with a dazed expression on its face. If the victim is led toward some danger, such as a ravine, fire, or the like, a second saving throw is allowed immediately; however, if this save fails the victim will proceed directly into danger. Once in reach of a harpy, a charmed victim will surrender completely, even allowing the harpy to attack and kill it without putting up any sort of resistance. The charm effect lasts one full round after all harpies have ceased singing.
