Know Bloodline Derivation

The caster of this spell can determine the bloodline derivation of an individual. The target individual is allowed a saving throw vs. spell with the following modifiers to the die roll (because stronger bloodlines are easier to detect): tainted, +2; minor, +0; major, -2; great, -4. There is a base 50% chance (minus 5% for every level of the caster) that a tainted bloodline passes unnoticed, even if the individual fails the saving throw. This spell does not work on inanimate objects.

The material component of this spell is a collection of trinkets representing the different bloodlines (Basaia is represented by the hawk, so a hawk feather or claw would be appropriate; scions of Reynir are attuned to the wilderness, making a pine cone or live twig suitable, and so on). The component that represents the target's bloodline disintegrates upon completion of the spell. If the spell is cast on an unblooded character, none of the totems are destroyed.

Notes: Common on Cerilia, the Birthright setting; unknown elsewhere.
