The Cities of Eternal Fog
The performer makes herself immune to the Vinculum and blood addiction when another Kindred’s Vitae is consumed. After this ritual is performed, if another vampire’s blood is taken in the same night, no step is taken toward a Vinculum with the provider of the blood, and no addiction to blood forms for the character. Of course, the blood donor has no idea that the recipient is immune. The ritual cannot be performed on another vampire, only on the caster’s self. The ritual does not countermand or alleviate any existing Vinculum to which the caster is already subject.
