200 XP
Actions
Multiattack
The harpy makes two attacks: one with its claws and one with its club.
Claws
Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 6 (2d4 + 1) slashing damage.
Club
Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) bludgeoning damage.
Luring Song
The harpy sings a magical melody. Every humanoid and giant within 300 ft. of the harpy that can hear the song must succeed on a DC 11 Wisdom saving throw or be charmed until the song ends. The harpy must take a bonus action on its subsequent turns to continue singing. It can stop singing at any time. The song ends if the harpy is incapacitated.
While charmed by the harpy, a target is incapacitated and ignores the songs of other harpies. If the charmed target is more than 5 ft. away from the harpy, the must move on its turn toward the harpy by the most direct route. It doesn't avoid opportunity attacks, but before moving into damaging terrain, such as lava or a pit, and whenever it takes damage from a source other than the harpy, a target can repeat the saving throw. A creature can also repeat the saving throw at the end of each of its turns. If a creature's saving throw is successful, the effect ends on it.
A target that successfully saves is immune to this harpy's song for the next 24 hours.
Quick Reference
Running This Encounter
Harpies are ambush predators that excel in aerial combat, so position them on cliffs, in trees, or circling above the party before combat begins. Use their luring song ability to separate party members and force disadvantageous positioning. They should target spellcasters and ranged attackers while staying airborne to avoid melee combatants. Consider using 2-3 harpies together to overwhelm a party through action economy.
Combat Tactics
Harpies lead combat by using their luring song on the most vulnerable targets to isolate them from the group. They stay mobile in the air, attacking from range with talons and claws while retreating upward when threatened by melee fighters. If outnumbered or bloodied, they attempt to flee rather than fight to the death.
Environment & Setting
Harpies nest on high cliff faces, isolated islands, or dense forest canopies where they can observe prey from above and retreat to inaccessible terrain. Encounters should take advantage of vertical terrain to maximize their aerial advantage.
