Affliction Resistance (Ex)

Your body is honed to fight off even the most virulent illnesses. Whenever you succeed at a saving a throw against a disease or poison, you become immune to that disease or poison for a number of hours equal to half your tier. If you are affected by the disease or poison and succeed at a saving throw to cure it, you automatically cure yourself of the affliction (even if it would normally require more than one saving throw to cure), and you become immune to it for a number of hours equal to half your tier.
