The following rituals do not adhere to the same rules as other forms of magic, in large part because they build on a Discipline that is not truly a form of sorcery. To learn Abyss Mysticism, a Cainite must have at least one dot in both Obtenebration and one dot in Occult. Such a character may not learn Abyss rituals rated higher than her Obtenebration or Occult score (whichever is lower). Casting Abyss rituals requires a successful Wits + Occult roll, for which the difficulty equals 3 + the level of the ritual (maximum 9). Only one success is required for a ritual to succeed. Should a roll to activate an Abyss ritual fail, the Storyteller is encouraged to create particularly horrible consequences or side effects; the Abyss demands a heavy penance for failure.

Unlike normal rituals, each Abyss Mysticism ritual costs 3 time the ritual level in experience points to learn. All rituals of Abyss Mysticism also have permanent side effects associated with learning and using them, as befits the alien and malignant nature of the Abyss. Under no circumstances do Flaws obtained from these side effects reward the vampire with bonus or experience points, nor can they be bought off.
