Custom Blood Magic: Ritual

A ritual that taints those present over many nights. Magical hieroglyphics, spiced blood, and incense are all signs and elements of the ritual. Each night spent at the temple or court of the followers of set increases the taint that infects those who are staying with them. The ritual encourages the target to taint themselves with their own deeds over the nights. Those who stay a full five nights find themselves facing accumulated taint capable of eroding their former selves and replacing it with a base and corrupted identity.  The spell's corruption is subtle, the longer it lasts the longer the incubation period that precedes it. Those touched for only an hour don't experience an incubation period, while those corrupted for a night do not manifest the change until an hour has passed. Characters are groggy during the incubation period ( no penalties,) they don't recognize the setite's as the source of this and feel no need to confront the serpents. This ritual changes the target's nature, their true self. Ritual duration based on number of nights it was successfully cast on the target: One night - one hour, no incubation Two nights - one night, one hour incubation Three Nights - two nights, one night incubation Four Nights - Five nights, two night incubation Five Nights - Permanent, several month incubation.
