This spell is used to sustain a spell with the life force of a single person. The spell must be a single target spell that affects only one person, the target of the Life Bond, and has a Circle less than the Circle of the Life Bond. Once both spells are cast the target is subject to the effects of the other spell for as long as he lives unless the bond is broken. If the sustained spell normally places burdens on the caster, then they are placed on the target instead.
To achieve the bond the subject must consent, and make a simple Spirit roll, followed by a simple Phys roll. A failure on either roll causes both spells to fail and the subject loses 5 Phys forever. The Life Bond counts as a maintained spell for the target and the caster.
power+1 Phys, or +1 Spirit on the rolls to accept per Power Level
