Custom Blood Magic: Ritual

Extended Gift (Basic Hermetic Ritual):

 

Kindred have often relied on the efforts of kine to protect there holdings  and even their unlife when they slumber. Feeding them vitae gives temporary  supernatural gifts to use in their defense. The Warlock with suitable  medicinal knowledge, however may be able to overcome the limitations of a   mortal's consumption.

Over the course of feeding a ghoul, the thaumaturge will draw a liter of  blood from the intended mortal. They will infuse the mortal's blood with  powdered Slippery Elm Bark, long used by herbalists to purify blood. They will then expend a mental trait equal to the amount of blood to be added to  the ghoul's stores, (up to three). They will then feed the ghoul the  solution as well as their own vitae, adding to the amount of kindred vitae  the ghoul can hold in their system.
