The Siren Vanquishing Spell is a spell used to vanquish sirens.


In Witch Perfect, this spell was cast by Maggie Vera when she thought that the Maestro was a siren, although it failed since the Maestro was not actually a siren but rather the conductor responsible for teaching them their song.


Your voice I vanquish,
Your song I destroy,
Killer of man, Stealer of joy!
Die, Siren!


  • The effect of this spell is currently unknown as it has never been successfully cast.
  • The reasoning for this spell is unclear as sirens in this series are taught their song by the Maestro, meaning that any being could become a siren. The Hilltones, aside from Maggie, were not even aware that they had been made into sirens.
