Harpy är en CR1-varelse från Monster's Manual. Men de har ett intressant drag som heter Luring Song , vilket är ganska unikt.
Luring Song.
The harpy sings a magical melody. Every humanoid and giant within 300 feet 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 feet away from the harpy, the target can take the Dash action on its turn to move 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.
Tyvärr, för det unika i detta drag är det inte listat i DMG (s. 280-281) hur denna funktion påverkar dess utmaningsbetyg. Detta är olyckligt eftersom detta förhindrar några mer meningsfulla, beräknade anpassningar av samma skicklighet till andra specialbyggda monster.
Hur skulle Luring Song påverka Challenge Rating för ett givet monster, och / eller isolerat, på sättet som visas i tabellen Monster Funktioner i DMG s. 280-281?
