Ancestral Suspicion
Ancestral Suspicion Level 5
Elf
Ancestry: Elf
Long-lived elves have seen civilizations rise and fall, often at the hands of outside forces. As a result, they have developed a wariness of others who might seek to influence or control them. You've been trained to resist such manipulation, gaining a +2 circumstance bonus to saving throws against effects that would make you Controlled, such as Dominate, and to Perception checks to Sense Motive when trying to determine if a creature is under the influence of such an effect. When you roll a success on a saving throw against such an effect, you get a critical success instead.
