phantasmal image
Phantasmal Image is a powerful upgrade to the Mirror Image spell that Illusionists learn. When an attacker hits a Phantasmal Image, one of the images disappears, returning damage to the attacker at the same time. Phantasmal Image does not stack with mirror image, and cannot be cast in combat. The number of images is equal to 2d4 + level/8 Phantasmal Image deals light damage. See showskill phantasmal image for more details.

mirror image
Syntax: cast 'mirror image' With this spell, an illusionist creates a number of illusionary copies of himself that seem to follow him whereever he moves. For the untrained eye it is almost impossible to distinguish those mirror images from the illusionist, so their attacks are likely to land on an illusion instead. Illusions hit that way dissipate, thus this spell will need to be re-cast in combat often. See showskill mirror image for more details
