Description: You can learn a lot of information from just a quick scan of an area or object.

Prerequisites: Listen (5 ranks), Spot (5 ranks)

You can make one Spot check and one Listen check each round as a free action. You also gain a +2 bonus on initiative checks.

Normal

Using Spot or Listen in a reactive fashion is a free action, but actively trying to make a Spot check or Listen check requires a move action.
