Once per day, an iron cobra's creator can order it to find and kill a specific creature within 1 mile, which it does as if guided by discern location. The creator must have seen or be holding an item from the specified creature for this order to function.
Special
|Poison
An iron cobra's bite injects poison from a hidden reservoir within its body. Because it is a construct, the cobra does not naturally produce this poison, and its creator must refill this reservoir manually. The reservoir holds enough poison for 3 successful bite attacks, after which the creature merely deals bite damage. Refilling the reservoir takes 5 rounds and provokes attacks of opportunity. The creator can fill the reservoir with any injury poison (typically black adder venom), though acid, alchemical substances, and even stranger liquids have been used. Black Adder Venom: Bite-injury; save Death; frequency 1/round for 6 rounds; effect 1d2 Constitution damage; cure 1 save.

This creature resembles a small metallic cobra. Its body sheens with a silver hue and its eyes are small pinpoints of red light.
The iron cobra is a construct that resembles a small, 3-foot-long cobra. Its eyes give it an evil and determined - and almost intelligent - look. The iron cobra is most often used to guard a treasure or to act as a bodyguard to its creator, though on some occasions it can be ordered to track down and slay any creature who is within 1 mile and whose name is known by the creator.
The iron cobra attacks by biting its opponent.
