Reality's Path (Rank 4) Edit
Perception is subjective, but the Philodox cannot afford that luxury. This Gift allows the user to sense whether what the subject believes to be true is actually false. A Jaggling of Falcon teaches the Gift.
The player rolls Perception + Enigmas (difficulty 7). A single success determines if what the subject is telling an unintended untruth. Three successes will discover if the subject was deliberately misled. Five successes or more will reveal the truth of the lie at its simplest level (it might tell who perpetrated a crime, but not why or who the perp was working for). Note that this Gift only works when a subject speaks what he truly believes; packmates can't go on "fishing expeditions" by throwing out names to determine who really committed a deed, for example. Reality's Path deals with knowable facts ("She never intended to return", "despite his boast, your brother didn't kill the Bane single-handed"), not greater spiritual truths.
