Warforged

The warforged were built to fight in the Last War. The first warforged were mindless automatons, but House Cannith devoted vast resources to improving these steel soldiers. An unexpected breakthrough produced fully sentient soldiers, blending organic and inorganic materials. Warforged are made from wood and metal, but they can feel pain and emotion. Built as weapons, they must now find a purpose beyond the war. A warforged can be a steadfast ally, a cold-hearted killing machine, or a visionary in search of purpose and meaning.
Warforged are formed from a blend of organic and inorganic materials. Root-like cords infused with alchemical fluids serve as their muscles, wrapped around a framework of steel, darkwood or stone. Armored plates form a protective outer shell and reinforce joints. All warforged share a common facial design, with a hinged jaw and crystal eyes embedded beneath a reinforced brow ridge. A sigil is engraved into the center of the forehead; this is unique to each warforged. Beyond these common elements of warforged design, the precise materials and build of a warforged vary based on the purpose for which it was designed. A juggernaut warrior is a massive brute with a heavy steel frame, while a skirmisher can be crafted from wood and light mithral to grant it lithe and elegant movement.
While they’re formed from stone and steel, warforged are living humanoids. Resting, healing magic, and the Medicine skill all provide the same benefits to warforged that they do to other humanoids. A warforged can focus its mind on its body as it rests, adjusting its shape and form to assume one of a few defensive postures. A warforged who expects heavy combat might focus on durability, while during a time of peace they might be content to adopt a lighter, less aggressive form.
