You use your various fields of knowledge to resist afflictions and other harmful effects on your body.
Benefit: Whenever you need to make a Fortitude save to resist a harmful effect, you may first make a Knowledge skill check using a Knowledge skill related to the effect. This check uses the same DC as the Fortitude save. If your Knowledge check is successful, you gain a +4 bonus on your Fortitude save to resist the effect. If the same effect causes you to make another Fortitude save at a later time, another Knowledge check is required. A Knowledge skill is “related” for purposed of this feat if it covers the type of creature or event which caused the effect you are trying to resist. For example, Knowledge (religion) would help you to resist attacks made by undead creatures or gods, while Knowledge (nature) would help you to resist the effects of weather or attacks made by plants. Refer to the Knowledge skill list for the topics covered by each knowledge skill.
