When a mirror image spell is invoked, the spell caster causes from 1 to 4 exact duplicates of himself or herself to come into being around his or her person. These images do exactly what the magic-user does, and as the spell causes a blurring and slight distortion when it is effected, it is impossible for opponents to be certain which are the phantasms and which is the actual magic-user. When an image is struck by a weapon, magical or otherwise, it disappears, but any other existing images remain intact until struck. The images seem to shift from round to round, so that if the actual magic-user is struck during one round, he or she cannot be picked out from amongst his or her images the next. To determine the number of images which appear, roll percentile dice, and add 1 to the resulting score for each level of experience of the magic-user: 25 or less = 1 mirror image, 26-50 = 2, 51-75 = 3, 75 or more = 4. At the expiration of the spell duration all images wink out.
