This is less of a path than it is a separate Discipline, as the power to resist Thaumaturgy can be taught independently of Thaumaturgy, even to those Kindred who are incapable of mastering the simplest ritual. Though the techniques of Thaumaturgical Countermagic are not officially taught outside Clan Tremere, unofficial methods are likely to exist. Any non-Tremere who displays the ability to resist Thaumaturgy quickly becomes the subject of potentially fatal scrutiny from the entirety of Clan Tremere.
The use of Thaumaturgical Countermagic is treated as a free action in combat and does not require a split dice pool. To oppose a Thaumaturgy power or ritual, a character must have a Thaumaturgical Countermagic rating equal to or greater than the rating of that power or ritual. The player spends a blood point and rolls the number of dice indicated by the character’s Thaumaturgical Countermagic rating (difficulty equal to the difficulty of the power in use). Each success cancels one of the opposing thaumaturge’s successes.
Thaumaturgical Countermagic is only at full effectiveness when used against Thaumaturgy. It works with halved dice pools against Necromancy and other mystical Disciplines, and is completely ineffective against non-vampiric magics and powers.
Thaumaturgical Countermagic can be learned by characters who are unable to learn Thaumaturgy (e.g., those with the Merit Magic Resistance). Any non-Tremere character with a rating in this power automatically gains the Flaw Clan Enmity (Tremere), receiving no freebie points for it. This power cannot be taken during character creation and cannot be spontaneously developed.
