As, with a soft thump, the fleshy body fell to the floor, suddenly Mithias finds the hand once more clasped into his own. Looking back, he could see the stump of a neck where it's head had once been, and yet, despite lacking what in any other humanoid would have been a critical point of it's anatomy, it seemed not to care. Furthermore, not only did it not bleed, but when you look at it, the stump seems to be solid. It's as if it has no inner organs or bone structure. Small holes seem to open and close in the creature's surface, like gaping mouths, as a second blow rocks the side of your face, once more blasting you into the hard, unforgiven wall of the structure. Had you not been able to regenerate from almost any damage, these blows would pose quite a threat. 

As you recover from the unexpected attack, the homonculus reaches down, picking up the featureless head, and attaches it once more to it's neck. There's a sickening squelch, and it moves around it's neck in ways impossible for any creature with bones. To all appearances, it's neck is once more attached to it's head, as if the cut had never occurred. It does the same with the hand, not seeming to bother putting up any kind of defense besides blocking the entryway. To all appearances, not only did it lack any form of self preservation instinct, but it would be quite a lot harder to kill than you had originally thought.
