Living steel is an ooze-like creature with the ability to change its form at will. Its natural form is roughly like a humanoid composed of silvery steel. The creature’s skin reflects bright light and absorbs heat, and moves with a liquid smoothness.
When living steel encounters another of its kind, both will fight to the death, the winner absorbing the loser. Living steel lairs in small nooks in its underground home, where they are able to relax into shapeless blobs of steel. These creatures eat iron, and live in areas where the ore is abundant. These creatures lay small portions of refined iron ore, which contain embryonic living steel that is fully-grown after one year.
COMBAT
Liquid steel is not normally hostile, but when provoked it becomes a ruthless foe that does not stop until its enemy is dead. The living steel usually stays in one form during combat, as it loses its natural armor while its liquid form changes. The creature reforms when struck; weapons slide right through it, only infuriating the living steel.
Alter Self (Su): Living steel can assume the shape of any creature of the same size and mass as itself. It cannot change its color, though its choice of forms may be unlimited. The living steel cannot fly, but it does gain the speed of the form it takes. This ability otherwise works like alter self, but the living steel can remain in the chosen form indefinitely. It can assume a new form or return to its own as a standard action. As it changes, the living steel temporarily loses its natural armor bonus.
Amorphous (Ex): living steel is not subject to critical hits. It has no clear front or back, so it cannot be flanked. Living steel can fit through the smallest of cracks and holes by reshaping its body. The living steel also has the ability to swim in molten or liquid metal, at a rate of 90 feet.
Liquid Steel Form (Ex): The living steel’s unique form provides it with certain natural defenses. First of all, it has Fire and Electricity Resistance 50. Electricity normally flows harmlessly through the living steel, and may affect other creatures near it. Fire temporarily liquefies the living steel, allowing it to reform into the form of its choice and attack in the same round. If either of these attack forms do harm a living steel, it will burst in a wide radius, into small pieces of liquid metal. The living steel must spend two rounds reforming to act again.
Vulnerability to Cold (Ex): Cold attacks affect living steel as a slow spell for two rounds following the attack. In this state, the living steel can only move at half speed, can only make one attack per round, and its alter self ability takes two rounds to complete. Also, the living steel suffers double damage from all attacks and loses its Damage Reduction ability.
The living steel first appeared in the Dragon Mountain boxed set (1993?) and later appeared in Monstrous Compendium Annual One (1994).
