Weapon attack. Living metal can mimic any kind of melee weapon known. Regeneration. Living metal can regenerate its molecular structure at the rate of 1 hit point per round. If it drops to zero hit points it is not destroyed, it instead starts reforming and becomes operational once it regenerates at least 10 hit points.
Shapechange. Living metal can assume the form of any object without mechanical parts or separated components. Also, it can assume the form of any living being with a mass and size that equals the living metal’s mass and size.
Vulnerable to Heat. Living metal is extremely vulnerable to heat damage like fire (provided it has a temperature high enough to melt the metal), laser weapons, and plasma, which all deal maximum damage. If the living metal drops to zero hit points due to heat damage it is not destroyed and starts regenerating again, but its maximum number of hit points is permanently reduced by one.
COMBAT & TACTICS
Living metal possesses an advanced AI that allows the construct to elaborate tactics and strategies. Both tactics and strategies work on multiple levels of efficiency and extend in the short, middle, and long term. What the living metal lacks, is a truly creative thought process and it tends to form predictable patterns
of behavior; in other words, a living metal is not able to “make a mistake” on purpose, to trick or lure the opponents into a trap.
DESCRIPTION
Living Metal is a shapeless mass of liquid metal with the size and mass of a standard medium humanoid. It can be composed of any metal alloy or more commonly steel. The shapechange ability allows the living metal to assume almost any form, but it cannot imitate any kind of mechanical device. The shapechange ability can also emulate colors and specific facial traits with a precision close to perfection.
HABITAT
Living metal does not require any specific environment to survive. The few contacts made by explorers with one of these things have been lethal and, according to records and chronicles, occurred on planets and artificial structures. The most accredited hypothesis is that many units exist in the galaxy, but they are scattered and seem to act without a clear and common goal.
BIOLOGY
Living metal is not a living being, but an artificial construct made by an unknown alien intelligence. The true purpose of this construct is now lost, together with its creators. How living metal works is the subject of debate, but some theories claim that a sophisticated form of nanotechnology is what keeps these constructs “alive”, while an advanced form of quantum electronic and AI grants the living metal a sort
of “intelligence”. To the present day, no one has had the chance of studying one, and if someone ever did, he never managed to disclose anything about the matter.
