Alter Ego

An assassin can create copies of himself to distract the enemy. As long as at least one copy is present on the battlefield, the assassin deals sneak attack damage to all creatures. This ability otherwise functions as the mirror image spell. The assassin creates one copy plus one copy for every 3 levels the assassin has beyond 3rd. He can use this ability a number of times per day equal to 1 + his Intelligence modifier.
