Fortitude

System: A character's rating in Fortitude adds to his Stamina for the purposes of soaking normal damage (bashing and lethal). A character with this Discipline may also use his dots in Fortitude to soak aggravated damage (Kindred cannot normally soak things like vampire bites, werewolf claws, magical effects, fire, sunlight or massive physical trauma).

Example: A vampire with Fortitude 3 has three dice to
                soak aggravated damage.
