A flesh golem is a ghoulish collection of humanoid body parts, stitched together into a single composite form.
Flesh golems are ghoulish, macabre horrors standing 8 feet tall and weighing about 500 pounds.They walked and moved with a stiff-jointed gait, as if not in complete control of its body. A flesh golem could not speak, although it could emit a hoarse roar of sorts. The golems wore whatever clothing its creator wished, though usually it was just a ragged pair of trousers and normally carried no possessions or weapons. 
While typically mindless, a flesh golem would sometimes possess the memories of the beings from which it was created. In such instances, they might eventually become an intelligent, free-willed being.
Flesh golems were constructed using the physical body parts of once-living creatures. These would have to be collected from at least 6 different corpses, one for the torso, head (including the brain) and each limb, though sometimes more bodies are needed. The bodies used are often humanoids or monstrous humanoids, but any physical living creature’s parts are usable. Special unguents and bindings are required to keep the flesh bound together during creation. 
When a flesh golem engages in combat, there is a small, but cumulative chance that its elemental spirit will break free and the it will go berserk. The uncontrolled abomination will go on a rampage, attacking the nearest living creature or smashing some object smaller than itself if no creature is within reach, then moving on to spread more destruction. If the golem'a creator is within close enough, they could try to regain control by speaking firmly and persuasively to the golem.
A flesh golem, like other similar constructs, was immune to any Spell that can be resisted. Magical fire is capable of damaging flesh golems and cold is able to slow them. Magical electrical discharges actually heal a damaged flesh golem, though if they are not damaged, they will actually grow in strength.
