Consequently, these spells are useful for confounding or delaying foes, but useless for attacking them directly. For example, it is possible to use a silent image spell to create an illusory cottage, but the cottage offers no protection from rain. A clever caster, however, can take pains to make the place look old and decrepit, so that the rain falling on the occupants seems to fall from a leaky roof. A glamer spell changes a subject's sensory qualities, making it look, feel, taste, smell, or sound like something else, or even seem to disappear. Like a figment, a pattern spell creates an image that others can see, but a pattern also affects the minds of those who see it or are caught in it.
All patterns are mind-affecting spells.
This impression is totally in the minds of the subjects. It is a personalized mental impression. Third parties viewing or studying the scene don't notice the phantasm at all. All phantasms are mind-affecting spells. The caster weaves it from extradimensional energies.
