Dread Secret [Skill]
Everyone has a skeleton or two in the closet.
Prerequisites: History as a trained skill, 6th level
Benefit: Once per [Encounter] as a swift action, you may attempt a History check to discover a terrible secret relevant to a single opponent (DC 10 + 1/2 opponent's level + opponent's Intelligence modifier). A successful check means that you can speak that terrible secret as a standard action. Your target must make a successful Will save (DC 10 + 1/2 your level + your Intelligence modifier) or be [Dazed] for two [Rounds]. A successful Will save still leaves the target [Sickened]. This ability cannot be used on a given creature more than once per [Scene].
