[Spells help] mirror image
 
Syntax: cast 'mirror image'

Mirror image creates several copies of the casting sorceror.  Any
attacker must first discern which image is the actual person before any
damage can be inflicted.  Even after a hit is scored, the images blur and
rotate about, making it likely that the attacker will continue to strike
out at images.  Each time an image is hit however, it will disappear.
