Hi welcome to the forum! I’m Siofra from Cape Cod. I am an Eclectic Witch, but I have not practiced or learned much about Voodoo anythings I’m sorry to say. However, I did find some good information for you to review. I’m trying to think if maybe @Francisco or @MeganB or any other coven members have some guidance for you…
In the meantime, I found these articles regarding your question:
Voodoo and Hoodoo. Opinions/ knowledge?
What’s your guys opinion on Black/Dark Magick?
I hope those help you & the information in the replies is useful to you.
