It is possible to make a Nganga.
A Nganga is a voodoo cauldron that houses the spirit of Death. By imprisoning it in nails, broken glass, feathers, human blood, railroad spikes, bullets, chains, and other binding materials. It's believed to have extraordinary powers, to curse, or to cast any spell against or for someone.
I don't know how to construct one... just that I've known them to exist. Does anyone that practices voodoo know how?
