What does some wire from paper clips, a little green stuff, leftovers from a Mantic Zombie and some hot glue-gun glue get you? Another Vivimancer monster for D&D.
So this thing will be able to extend is limbs in a whip like fashion doing damage up to near/close range and granting at least two attacks per round, although it could use one of its legs also at a pinch. Its tough, sinew flesh will grant it some damage reduction from non-magical weapons. I may even make it able to climb walls easily.
