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 normal weapons, but their most insidious ability is their song. When a harpy sings, all creatures (other than harpies) within a 300' radius must succeed on a save vs. Spells or become charmed. The same harpy’s song cannot affect a creature that successfully saves again for 24 hours. A charmed victim walks toward the harpy, taking the most direct route available. If the path leads into a dangerous area (through ame, off a cliff, or the like), that creature is allowed a second saving throw to resist the charm. Charmed creatures can take no actions other than to defend themselves. A victim within reach of the harpy offers no resistance to the monster’s attacks. The effect continues for as long as the harpy sings, and for one round thereafter.
