The ritualist can create a magical tracker called a Bloodstone which she can mystically sense from afar.

Ingredients: A pebble of magnetized iron ore and an additional Rouse check worth of blood that can be from any source except the caster (who still contributes their own Blood as well).

Process: The ritualist submerges the pebble in the mixture of blood while repeating a mystical chant once every 10 minutes for the next hour. The pebble slowly absorbs the blood, taking on a deep red color. 

System: Once the Bloodstone Ritual is complete, you have a mystical connection to the stone. You can tell its relative position and distance from you at all times. A caster can create a number of Bloodstones equal to the number of dots of Resolve she has. If a Bloodstone is Obfuscated or otherwise supernaturally hidden, the caster can follow the trail until she reaches the general location of the stone (within 15 steps). The connection becomes blurred at that point, and she can no longer feel the Bloodstone’s precise location beyond that point until it is no longer under the effects of Obfuscate. A Bloodstone lasts for one month and one day before the red color fades and the pebble becomes inert.

Duration: One month and one day
