The necromechanical is a highly advanced undead creature built and raised by the technically skilled necromancers of the world below. It consists of preserved body parts (not always collected from one single person), attached to a metal endoskeleton. This makes them very durable compared to lesser undead creatures. They are strong and heavy, but can –once properly assembled- be raised and commanded by their creators like any other undead creature.
Their distal limbs are often reinforced by additional metal to prevent them from damage, especially when used for defensive or offensive purposes - as they very often are. They are often enhanced by the addition of appendages that can improve their postural control, locomotion, or simply by making them more lethal to anyone they might meet.

Thanks for looking!

(And remember, if you notice a part that doesn't fit you can just think it was put together by a very sloppy necromancer. They sometimes are sloppy, believe me!)
