The Gethsemani is able to invoke a cursed mockery of the
miraculous power of transubstantiation, in this case turning mundane
liquids into her own Vitae. The miracle is usually performed
to nourish a growing congregation of Kindred or ghouls where
mortal stigmatics are unavailable to sustain a flock. By placing a
single drop of personal Vitae in a volume of any liquid that could
be safely consumed by mortals, that substance is mystically transformed
into the Kindred’s own blood, capable of providing whatever
benefits her own Vitae already does. (A volume of liquid
equal to at least a jug of wine is required. A drop of water doesn’t
do it.) Other Kindred who taste this transformed blood recognize
it as belonging to the invoking vampire, as there is no effective
difference between it and the character’s own Vitae. As with any
exposed Vitae, the usefulness of this blood diminishes rapidly,
becoming inert only a few minutes after its creation.
