Pathfinder's Sense is the Auspice ability of the Irraka. It is described as the Irraka having an easier time perceiving spirit influence.

Mechanically this means that whenever an Irraka makes a roll to peer from one world to the next or to see ephemeral spirits they receive a +2 to the roll. In addition Irraka recieve a +2 to any rolls made to locate the direction of a Locus while in it's area of influence.
