The Siren's Song
Welcome again to Masters and Minions, where I strive to give you interesting NPCs and encounters that can be placed easily into your game. This week’s encounter is with a small group of sirens who have been luring local fishermen to their deaths.
For the past month or so, whole crews of fishing boats have been going missing, their boats either never returning to port, or found washed up on shore with no signs of the crew. The PCs have been asked by the dockmaster to look into these disappearances.
When the PCs sail out to the fishing grounds the missing fishermen used to frequent, they are attacked by four sirens, who begin to sing in an attempt to lure the PCs to their deaths.
SPECIAL ABILITIES
Captivating Song (Su)
A siren's song has the power to infect the minds of those who hear it, calling them to the siren's side. When a siren sings, all creatures (aside from other sirens) within a 300-foot spread must succeed on a DC 18 Will saving throw or become captivated. A creature that successfully saves is not subject to the same siren's song for 24 hours. A victim under the effects of the captivating song moves toward the siren using the most direct means available. If this path leads into a dangerous area such as through fire or off a cliff, that creature receives a second saving throw to end the effect before moving into peril. Captivated creatures can take no actions other than to defend themselves. A victim within 5 feet of the siren simply stands and offers no resistance to the siren's attacks. This effect continues for as long as the siren sings and for 1 round thereafter. This is a sonic mind-affecting charm effect. The save DC is Charisma-based.
