Description: You are endlessly curious and attentive, yet calm and focused.

Prerequisites: Alertness, Void Use, INT or WIS 13, Spot (9 ranks)

Once per encounter, the character may make a Spot check against one target (DC 10+ Target's hit dice +target's Charisma modifier). If this Spot check is successful, you learn one of the following: the target's lowest saving throw type, the target's lowest ability score modifier, one martial art style known by the target, or the target's highest class level. Note that specific values are not learned (such as the exact bonus of a target's highest saving throw)
