Several illusory duplicates of the character pop into being,
making it difficult for enemies to know which target to attack.
The figments stay near the character and disappear when struck.
Mirror image creates 1d4 images plus one image per three
caster levels (maximum eight images). These figments separate
from the character and remain in a cluster, each within 5 feet of
at least one other figment or the character. The character can
move into and through a mirror image. When the character and the
mirror image separate, observers cant use vision or hearing
to tell which one is the character and which the image. The
figments may also move through each other. The figments mimic the
character's actions, pretending to cast spells when the character
casts a spell, drink potions when the character drinks a potion,
levitate when the character levitates, and so on.
Enemies attempting to attack the character or cast spells at
the character must select from among indistinguishable targets.
Generally, roll randomly to see whether the selected target is
real or a figment. Any successful attack roll against a figment
destroys it. A figments AC is 10 + size modifier +
Dexterity modifier. Figments seem to react normally to area
spells (such as looking like theyre burned or dead after
being struck by a fireball).
While moving, the character can merge with and split off from
figments so that enemies who have learned which image is real are
An attacker must be able to see the images to be fooled. If
the character is invisible or an attacker shuts her eyes, the
spell has no effect, though being unable to see carries the same
penalties as being blinded: In addition to the obvious effects, a
blinded creature suffers a 50% miss chance in combat (all
opponents have full concealment), loses any Dexterity bonus to
AC, grants a +2 bonus to attackers attack rolls (they are
effectively invisible), moves at half speed, and suffers a
4 penalty on most Strength- and Dexterity-based skills.
