Once per day as an immediate action when the rogue is hit, the rogue can create a single shadow duplicate of herself, as per mirror image. The GM randomly determines whether the attack hit the rogue or the shadow duplicate. The shadow duplicate lasts for a number of rounds equal to the rogue’s level, or until the shadow duplicate is dispelled or destroyed. This ability does not stack with the mirror image spell. The caster level for this ability is equal to the rogue’s level. A rogue can use this ability one additional time per day for every 5 rogue levels she has.
