Exorcist Type : Infusion Spirit (Evil Spirits)

The Serpent Spirits have a unique type of spirit because whenever they mix with another kind of spirit or flesh whether animal, human, or even an evil spirit, it only results in a temporary possession known as "Infusion Spirit." Through this, they can use the body of a being. However, this contaminates the spirit, especially when Satan is involved. If Satan's infusion spirit is left unchecked within a being, it may be consumed by evil, similar to what happened to Judas Iscariot.
