Selective Health

You are resistant to most illnesses that strike those around you, but vulnerable to the contagions of evil.

Prerequisites: Aasimar

Benefit: You gain a +2 trait bonus on Fortitude Saving Throws against diseases. However, whenever you must make a Fortitude saving throw against a disease inflicted by an Undead creature or evil outsider (such as mummy rot or a vrock's spores), you do not gain this bonus, and instead take a –2 penalty on your Fortitude Save.
