Sedivore: The Untittled
This is the skill of picking up on when someone is lying to you. This could mean reading their body language and movements, but it could also be the application of logic to notice that what they are saying does not make sense. Keep in mind that this is not just strait lies, but lies of omission and minor deceptions as well. The fact that someone is deliberately attempting to avoid mentioning something or is wording something oddly can also be picked up by this skill.
