The Ritual of Pochtli
Description: The actions of this ritual were actually developed in concert with several Ghiberti vampires who have been residing in Pochtli's temple for almost two decades. Because both families had a lengthy history of elaborate ceremonies, they felt more comfortable researching with one another than with the mainstream Giovanni. What they have developed is something of a meta ritual. It cannot be cast by itself, but only in conjunction with another Necromantic ritual, or with the heavily ritualized use of a Necromantic path.
The action of the ritual is this; Two or more Kindred necromancers restrain a mortal vessel and inflict incisions in the shape of blasphemous Egyptian hieroglyphs or Aztec symbols. They then drink from these injuries. Each participating Necromancer must make his own cut and drink from no other cut.
Thereafter, the Necromantic power the Kindred seek to employ gains the benefit of all the participants' knowledge. This ritual makes it possible for Necromancers to create truly fearsome feats of death-magic.
System: The player rolls to activate this ritual as normal - Intelligence + Occult, difficulty 5 (because it's a Level Two ritual). If the roll succeeds, the Kindred who have participated in the ritual may work together on the path or ritual the Ritual of Pochtli is intended to assist, and players share successes. Note that the primary application of Necromancy requires its own roll, and that successes (and failures) garnered by the group are pooled.
If a Giovanni tries to use the Ritual of Pochtli with a path or ritual, she must have the know-how to use Necromancy in the Ghiberti or Pisanob style (see below). Additionally, all Kindred participating in the ritual must know the Ritual of Poctli as well as the ritual or path power the group seeks to enact.
For example, three Pisanob attempt to use the Ritual of Pochtli as well as the ritual or path power the group seeks to enact.
For example, three Pisanob attempt to use the Ritual of Pochtli to flay the soul from a Sabbat ghoul who has invaded their haven. Each player succeeds on her roll to use the Ritual of Pochtli, and then they collectively attempt to use the Level Four Bone Path power, Soul Stealing. The first player gains three successes, the second gets two, and the last gets only one (which would have been two, but she rolled a 1). These combine for a total of six successes, reaping the ghoul's soul from his body for a total of six hours.
The downside of this power is that a single player's both negates the successes of the entire group, resulting in a horrific failure for the ritual workers.
