This Power of Three spell was written by Phoebe Halliwell to vanquish the evil within Magic School. Once cast, the spell creates a transparent force field around the caster which rapidly expands. All evil that touches the force field is instantly vanquished. Once the force field reaches its full size, it shatters, sending a powerful energy blast in all directions. This spell was powerful enough to vanquish the Tribal Demons and their leader.
- "Within this school, place of power,
- Evil roams and demons cower.
- We call upon the power of three,
- To clear this school and set it free.
- Hear now the witches' calls,
- Rid all evil from these walls.
- Demons, spirits and other ghouls,
- We banish you from this school."
