I ran a customized monster in 5e. A siren. It's ability was a straight copy from the Banshee but instead of knocking unconscious, it caused the player to spend their full speed running towards the creature.
The party was at sea and heard them coming.
They ended up lashing themselves and the crew to the masts and railings, giving disadvantage on a lot of stuff.
They were prepared and they won, but damn it was cool to see the party do exactly what they were supposed to do against sirens.
