Sabbat (VTES)

From the White Wolf Wiki, the most complete White Wolf reference

Sabbat was the largest and last of the expansion sets for the Vampire: The Eternal Struggle trading card game to be released by Wizards of the Coast. It introduced many new rules and Kindred to fully add the Sabbat to the game (previous expansions and the original edition focused on vampires of the Camarilla or Independent clans).

As well as many new Lasombra and Tzimisce vampires, the Sabbat expansion also added antitribu vampires of all clans and rules for Sabbat titles, rituals and tactics. Each pack of expansion cards included an update explaining these new rules.
