Immunology

Source Character Operations Manual pg. 45

Immunology is the study of how living creatures’ bodies fight off diseases and other maladies.
Booster: You boost a creature’s immune system, granting a +2 enhancement bonus to Fortitude saving throws.
Inhibitor: You deliver a potent compound that weakens a creature’s immune system (or creates vulnerabilities in nonliving creatures), imparting a –2 penalty to Fortitude saving throws.

Breakthrough

You can use the following ability when you achieve the breakthrough for this field of study.
Suppress Disease (Ex): As a standard action, you can create and deliver a formula that supercharges a target’s immune system. When injected, the formula allows the target to ignore the effects of the highest stage (not including the disease’s end state) of a single disease affecting them for 1 hour. The disease doesn’t progress normally during that time, but this time doesn’t count toward the disease’s duration. If you are at least 7th level, the target ignores the effects of the highest stage of a single disease for 24 hours. If you are at least 13th level, the target ignores the effects for 1 week.
