No vampire Clans are given Blood Rituals, and it is not given in the course of the single-player game. Only one Tome exists in the Dark Ages, in the Tremere Laboratory )(Haus de Hexe 3) portion of the Haus de Hexe in Vienna. It is guarded by a Tremere Lord, just before the Arcanum piece at the end of the Lab.
This Discipline includes the best control ability in the game, Prison of Ice, and one of only two spells that damage the target instantly, Call Lightning (Cauldron of Blood being the other). While the most powerful damage spell by far is Firestorm, Call Lightning is tactically superior against already moving targets.
This is the ultimate defensive skill, shutting down all of its targets' abilities, no matter whether they are vampires, beasts, or humans.
Call Lightning []
This ability can hit targets even if they are moving, but Firestorm is two to three times stronger for stationary targets. No vampire clans start with this skill; it is only available as a tome (one in the single-player game).
Ignore The Searing Flame []
While useful for reducing fire damage, the prerequisites are moderately high and the XP investment may be better spent on more generalized damage reduction abilities, like Stamina, Blood Stamina, and Fortitude.
Summon Elemental []
