Valued highly by regents across Cerilia, inheritance assurance guarantees that if a regent dies prematurely or far from home, his or her regency and bloodline pass to the chosen heir.
Both the regent and heir must be present for the casting of the spell. As long as the spell is in effect, the heir receives the scion's bloodline, abilities, and regency upon the instant of the scion's death. Even bloodtheft is impossible while this spell is in effect. The spell ends immediately, however, if the designated heir dies before the scion.
If bloodtheft is attempted with a tighmaevril weapon, the scion must roll a saving throw to prevent losing his or her bloodline and regency. The scion gains a +1 bonus to the roll for every 10 points of regency possessed.
This spell cannot be cast on an unwilling regent, but the heir can be unwilling. In such a case, the unwilling heir must be restrained during the casting in order for the spell to work.
The material components are a lock of hair from the scion and heir and a small silver paten on which the hair is placed. The paten is not consumed in the casting.
Notes: Uncommon in Cerilia, the Birthright setting; otherwise, virtually unknown.
