Destruction of Flesh.

You curse the target by firing a large piece of flesh at it. The target slowly begins to mutate into a lifeless, disgusting, pile of flesh.  The creature must roll a Wisdom save if it fails it will take 5d6 of damage per turn after initial damage rolled, if the save is successful it will only take 5d6 necrotic damage. If the targets no reaches 0 it can not roll for death saves. It immediately dies.
