Senofu Kpelie Mask

Introduction
This mask was made by the Senofu people of Burkina Faso. Masks of this type represented females, but were worn by men during initiation ceremonies, harvest rituals, and elaborate funerals to convince the spirits of the deceased to leave their homes.

Effects
This mask is able to create a repelling field which causes any spirit or demon to disappear. Unfortunately, this mask might mistake anything which slightly resembles a demon, such as a pair of headphones, a horned helmet, or a hanging sheet for a demon and make it disappear.

Trivia
This artifact was seen in the episode "Personal Effects", where it mistook a pair of headphones for a demon and tried to create a repelling field.
