Seal the Gates of Blood

Setite Sorcery

Egyptian doctor-priests prescribed an amulet of Set to prevent miscarriage and excessive menstrual bleeding, as the Dark God's brutal masculinity frightened the womb into shutting tight. Egyptian Setites still vend the charm, though they do not tell clients about one of its powers.
System: The amulet requires no special effort to scribe and consecrated. A woman who wears the amulet does not miscarry, and her menses are greatly reduced. The menstrual blood, however, actually passes to the lector-priest: on blood point, once a month, but never more than that. If the recipient does not wear the amulet through one menstrual cycle, the spell breaks. The spell otherwise lasts one month per success rolled.
