A banshee is a demon who wanders the Earth feeding on souls in great pain. Hunting only at night, this demon uses her voice as a high-pitched call to locate a victim by hearing the inner cry. She does this by honing in on the waves of pain that emanate from the stricken. When she locates the victim, her cry turns into a lethal scream which causes a person's blood vessels to burst. When a banshee targets her scream at a witch, it turns the witch into a banshee.

Spell to Track a Banshee:
The piercing cry that feeds on pain,
And leaves more sorrow than it gains
Shall now be heard by one who seeks
To stop the havoc that it wreaks.
