Perform the spell below when you are around other people and you would
rather them not notice you. This won't make you really invisible, like
David Copperfield, but it will draw attention away from you and make
others seem to not notice you are there at all.
Close your eyes and imagine a sphere of white light around you. Then
imagine that the light starts to get blurry. It then takes on the colors
and shapes of the environment around you. You fade into the light,
becoming a part of it, until you completely disappear into the camouflage
of the circle of light around you.
