Harpy 5e Guide: Luring Song, Saving Throws, and Cliff Encounters
Rules baseline: 2014 D&D 5e, SRD 5.1. Open the for complete statistics. The beacon, terrain, and harpy’s behavior in the encounter are original suggestions.
Monster overview
A harpy is a Medium monstrosity with a human head and torso, broad vulture wings, and bird legs ending in talons. It speaks Common, flies 40 feet, and can turn an inviting melody into a magical lure. A rocky spur above a coast, a broken bridge, or a high ruin gives it somewhere to perch while prey approaches on foot.
The harpy is CR 1, but the approach matters as much as the creature. A song across level ground pulls a character out of position. The same song near a broken cliff path can put them in reach of a serious fall. Give players a chance to inspect that route before a failed save takes away their choices.
How Luring Song works
The harpy starts Luring Song as its action. Humanoids and giants that can hear it within 300 feet make a DC 11 Wisdom save. On a failure, a target is charmed and incapacitated while the song lasts. On its turn, if it is more than 5 feet from the harpy, it uses its movement to approach by the most direct route. It ignores other harpies’ songs while affected by this one.
Keep three repeat-save triggers handy. A charmed creature can roll again before entering damaging terrain, when damaged by a source other than the singing harpy, and at the end of each of its turns. A success ends the effect and makes it immune to this harpy’s song for 24 hours. The creature’s movement can still trigger opportunity attacks.
The singer spends a bonus action on each later turn to keep the song going. It can still fly and take its action, including its claw-and-club Multiattack. Incapacitating the singer ends the song for everyone. It can also choose to stop. A creature that cannot hear the initial song avoids that save. If a player uses wax, cloth, or another improvised measure, establish whether it actually blocks hearing before initiative.
Make the cliff visible before the song starts
Show a snapped trail rail, a torn pack below the ledge, and a sheltered alternative. Let players see where the harpy could draw them. A sheer cliff with a narrow path gives rescuers something concrete to do while an affected character repeats saves. A ledge with no place to tie off and no way to approach the singer leaves much less room for a rescue.
At the table, put a marker beside each affected creature in the initiative tracker. Remove it on a successful save and mark that creature’s immunity separately if the harpy could start singing again.
Ready to run: The signal at Split Gull Point
Situation. One harpy hunts from a spur beside a coastal signal hut. A ferryman asked the party to light the hut’s lantern so an approaching boat can find the safe channel. The boat turns away in six minutes if the signal stays dark.
Layout. The path approaches from the west. It ends at a 10-foot gap, 30 feet above a shingle beach. The hut is 20 feet beyond the far lip. The harpy perches at trail height on a spur 5 feet past that lip. Inland stone steps start 20 feet before the gap and curve around the headland to the back of the hut. A ringbolt on the near side of the gap can anchor a safety line.
Opening. From the foot of the steps, the party can see the broken path, the harpy, and old rope caught on the near ringbolt. A weathered arrow points inland toward the hut. The harpy watches the exposed trail and begins its song in initiative if anyone advances past the stairs on that trail.
Choices. The inland route takes three minutes. In this scene, the harpy stays focused on the exposed trail and the stone ridge conceals the approach to the hut. The party can reach the back door that way and use one action to light the lantern with a ready flame. On the direct route, tying a safety line to the ringbolt before advancing takes an action per person in initiative. A line short enough to stop a character before the gap keeps them on the ledge while they attempt end-of-turn saves.
If combat begins. Roll initiative before the first song. A charmed traveler on the exposed path gets the damaging-terrain save at the gap before stepping off. If they fail and fall, resolve the 30-foot drop and then offer the repeat save triggered by that damage. The harpy stays near the spur until it has taken at least 20 damage, then abandons the hunt and flies out over the water. It lets travelers retreat up the inland steps.
Finish. A lit lantern guides the boat in and earns the agreed 25 gp. If the party retreats or misses the boat, the ferryman can arrange passage the next morning. A casualty on the beach can be reached from a rough path farther west.
Prepare for your party
Check the encounter balancing guide before combining the song with a drop. A 30-foot fall can take a low-level character out of the fight. For an easier scene, lower the ledge to 10 feet and give the party a spare rope at the trailhead. For a harder rescue, put an affected keeper on the exposed path as the party arrives. Use the coastal and sea encounters for what happens after the boat reaches shore.
