Illusion Casting

Illusion Casting is the ability to cast illusions, which are perception of the mind. Users can cause those affected to see and hear what the caster desires. Sometimes, these illusions are so realistic that the affected can experience touching them.

Examples
Rex Buckland could create powerful illusions that appeared substantial. He once decorated an entire apartment with an illusion and he and Phoebe Halliwell were both able to sit on an illusionary sofa.

The Unnamed Wizard proved quite capable of casting illusions, allowing him to create a duplicate of himself that was set on a time loop. He was also shown

touching and even eating his own illusions, though he mentioned he felt nothing.
