Necromancy is at once a Discipline and a school of magical learning, all dedicated toward the command of the souls of the dead. It has some similarities to Thaumaturgy in that, rather than being a strict linear progression of powers, Necromancy consists of several "paths" and accompanying "rituals." Well-trained and puissant vampiric necromancers can summon the dead, banish or imprison souls, and even reinsert ghosts into living - or unliving - bodies. Needless to say, the study of Necromancy is not widespread among the Kindred, and its practitioners - primarily Giovanni Kindred - are shunned or ignored whenever possible.
Over the centuries, the various schools of vampiric Necromancy have diversified, leaving three distinct paths of necromantic magic available to Cainites. All necromancers first learn the so-called Sepulchre Path, then extend their studies to the Bone Path or the Ash Path as time and opportunity permit. The Sepulchre Path is always considered the character's "primary" path; it increases automatically as the character increases her overall Necromancy rating. The Bone and Ash Paths must be bought separately, using the experience costs for secondary paths.
Like Thaumaturgy, Necromancy has also spawned a series of rituals. While not nearly so immediate in effect as the basic powers of Necromancy, Necromantic rituals can have impressive long-term effects. Unsurprisingly, the elements of Necromantic ritual are things like long-buried corpses, hands from the cadavers of hanged men, and so on, and so obtaining suitable materials can be quite difficult. Scarcity of supply limits the frequency of Necromantic rituals, giving cause for many other Kindred to breathe a metaphorical sigh of relief.
System: A Cainite necromancer must learn at least three levels in the Sepulchre Path before learning his first level in either the Bone Path or the Ash Path. He must then achieve mastery in the Sepulchre Path (five levels) before acquiring any knowledge of the third path.
As with Thaumaturgy, advancement in the primary path (in this case, the Sepulchre Path) costs the normal experience amount, while study of secondary Necromantic paths incurs an additional experience-point cost. Because Necromancy is not quite so rigid a study as Thaumaturgy is, the rolls required to use Necromantic powers can vary from path to path and even within individual paths.
