All Kindred have a great amount of resiliance against bodily harm that would render a human injured or worse. This power however, magnifies that ability to incredible heights. With Fortitude a vampire can withstand even greater amount of damage and even Aggravated Damage. A vampire can even withstand the traditional banes of her existance for small periods of time (like Fire, and Sunlight). Among those who possess this Discipline are the Gangrel, Ravnos, and Ventrue.

For the purposes of Soaking normal damage (Bashing and Leathal), the vampire adds her  Fortitude to to the standard Stamina roll. The vampire can also soak Aggravated Damage (caused by fire, vampire or werewolf claws, sunlight, etc.) by rolling her straight Fortitude.
