Harpy

. .

The monster sings a magical melody, which lasts until the monster's Concentration ends on it.
Wisdom Saving Throw: DC , each in a -foot Emanation originating from the monster when the song starts.
Failure: The target has the Charmed condition until the song ends and repeats the save at the end of each of its turns. While Charmed, the target has the Incapacitated condition and ignores the Luring Song of other harpies.
If the target is more than 5 feet from the monster, the target moves on its turn toward the monster by the most direct route, trying to get within 5 feet of the monster. It doesn't avoid OpportunityAttacks; however, before moving into damaging terrain (such as lava or a pit) and whenever it takes damage from a source other than the monster, the target repeats the save.
Success: The target is immune to this monster's Luring Song for 24 hours.
