Heartseeker from Ultimate Equipment says.
A heartseeker weapon is drawn unerringly toward beating hearts. A heartseeker weapon ignores the miss chance for concealment against most living targets, though the attack must still target the proper square. This special ability does not apply against aberrations, oozes, plants, outsiders with the elemental subtype, or any creature specifically noted to lack a heart. Dose this weapon enchantment let the attack an enemy with
mirror image on as long as it has a heart beat?
