1st - You are able to put together information quickly; you are treated as taking 10 on Perception checks, and once per day you can re-roll any Knowledge, Perception, or Sense Motive later in the same day to try and get new information. You also gain the Urban Tracking feat for free.
4th - When you Appraise an item, you also learn all properties of it as well.
7th - When you choose to ready an action, you can ready both a standard and move action.
10th - When you are scryed and you pass the save, you can allow them to see just you and nothing around you; while connected in this way you can see and talk to the person scrying you, though they can still end the scry at their discretion. In addition, two times per day you can add a +10 untyped bonus to an INT- or WIS-based skill check.
