I had a basic understanding of how voodoo and shaman religion/magic is practiced in various ways throughout Africa.

But this article gives a great overview of Ghana, and how priests actually call each other out, to meet and prove who has better magic/spiritual power

These rivalries and accusations even go back and forth between the Pentecostal church and traditional priests, they often claim some "unique" abilities
