Wayward Siren

Multiattack. The siren makes two attacks, but can only make one attack with its claws.

Claws. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (2d4 + 2) slashing damage.

Whip. Melee Weapon Attack: +4 to hit, reach 10 ft., one target. Hit: 4 (1d4 + 2) slashing damage.

Luring Song. The siren sings a magical melody. Every humanoid and giant within 300 feet of the siren that can hear the song must succeed on a DC 13 Wisdom saving throw or be charmed until the song ends. The siren must take a bonus action on its subsequent turns to continue singing. It can stop singing at any time. The song ends if the siren is incapacitated.

While charmed by the siren, a target is incapacitated and ignores the songs of other sirens. If the charmed target is more than 5 feet away from the siren, the target must move on its turn toward the siren by the most direct route, trying to get within 5 feet. 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 siren, the target can repeat the saving throw. A charmed target can also repeat the saving throw at the end of each of its turns. If the saving throw is successful, the effect ends on it.

A target that successfully saves is immune to this siren's song for the next 24 hours.
