Custom Blood Magic: Ritual

By use of astronomical symbols and the casters blood, they can mark a person's spirit, allowing the caster to see where his subject is at anytime, even after they have died.The Ashipu must create a idol of the person with their known name carved into it, the idol must be a foot tall, made from living wood, and must be their true face, false faces created by any means will not work. The Idol takes a month to create and must be minimum Crafts x3, Higher crafts will prevent the heavens from mistaking faces. The caster must burn the idol, using the ashes and his or her own blood for a period of no less than one full lunar cycle, then uses the blood ash to paint the name of the target on a stone tablet carved with astronomical symbols. If the ritual is successful, he can afterwards learn the target's whereabouts by meditating while holding the stone in a trance like state, till the heavens whisper the desired information into his ear. This tablet will only work if the user is under the open night sky. The stone loses its power during summer solstice and winter solstice as well the spring and autumnal equinox. (Ritual failure requires a new idol and the Ashipu must restart from scratch.)
