Deviation

Deviation is the magical ability to deflect energies that are thrown in the direction of the deviator. This ability is highly similar to Telekinesis. The only difference is Deviation is a defensive power, and can only be used to barricade; while Telekinesis can be used defensively or offensively. Deviation can also be considered a force field or mental barrier. Prue uses Deviation to deflect energies back at demons throughout all seasons one through three, but this cannot be considered Deviation because her primary power of Telekinesis contradicts this. If a magical pertains the power of Telekinesis, they can't also pertain the power of Deviation because it's considered a subset of Telekinesis. A magical being can only pertain Deviation if they do not have the ability of Telekinesis.
