Fortitude (VTM)

Fortitude is supernatural resiliance. Masters of Fortitude can shake off normal wounds as if they were flea bites. They can are also semi-resistant to supernatural damage and sunlight. While this does not make them immune to these effects, it does make them more resistant to them. A master of Fortitude may just be horrible burned by being lit of fire, rather than actually dying from it.

Elder vampires have access to more unusual permutations of Fortitude that may allow them limited immunity to sunlight (for a few mintues, at most), allow them to harder their skin so that weapons shatter on them, or make themselves impossible to stake.

The Gangrel, Ventrue, and Ravnos show the greatest aptitude with Fortitude, but as one of the three 'natural' Disciplines, it's not uncommon to find other clans with Fortitude. Most elders will have at least some minimal skill at this Discipline, as it may well be what allowed them to survive so long!
