From Marduk’s Throat
Ritual · Vampire · Level 5
This ritual is the means by which Assamites can continue to reduce their Generation despite the limitations imposed by the Tremere Curse. It is also the mechanism by which the sorcerer caste maintains some influence and control over the Clan despite their small numbers, as the ritual’s difficulty means that only very experienced sorcerers can use it. The sorcerer creates an alchemical substitute for vampiric blood, allowing an Assamite who drinks enough to decrease her Generation. The ingredients include a wide variety of chemicals, herbs, and other exotic materials, but the most important ingredient is Kindred blood.
To reduce the drinker’s Generation by one level, the potion must incorporate a number of blood points from vampires of lower Generation than the drinker equal to four times the maximum blood point value of the desired Generation. For example, an Assamite who sought to reduce her Generation from Eighth to Seventh would need to procure twenty-eight points of blood from Kindred whose own Generation was Seventh or lower. Regardless of how much vitae that is, the result of the alchemical process will evaporate down into a thick sludgy material that the imbiber must consume in a single attempt.
The potion is foul, and requires the imbiber to successfully roll Willpower (difficulty 9). If that roll succeeds, the Assamite must then successfully assimilate the blood into her body. This requires an extended Willpower roll (difficulty 9), seeking 15 successes for a new Generation. Failures don’t stop the process, but they do deal six dice of lethal damage apiece (soaked normally). Assimilation is so painful and distracting that any attacks made against her during this time face a difficulty of only 2.
