The subject's outline appears blurred, shifting and wavering.
This distortion grants the subject concealment (20% miss chance).
A see invisibility spell does not counteract the blur effect, but a true seeing spell does.
Opponents that cannot see the subject ignore the spell's effect (though fighting an unseen opponent carries penalties of its own; see page 151).
