There are two different effects for this spell. You can choose to attempt to strike a target with a ray of bright purple energy, in which case the target is denied a saving throw and spell resistance. The other method produces no visible effect, but the target can attempt a save or use its spell resistance.
If successful, the spell surrounds the target with a personal glamer that causes him to behave as if you are under the effect of an invisibility spell. The glamer is spherical, emanating out to a five-foot radius from the target, and moves with him.
If you attack the target, or if the distance between you and the target is ever less than five feet or more than the spell's range, the spell immediately ends.
Material component: An eyelash encased in a bit of gum arabic.
