Wind Sight (Su)
Source: Advanced Class Guide, p. 47
The shaman ignores the penalties on Perception checks caused by wind and the first 100 feet of distance. At 7th level she can, as a standard action, hear or see into any area—as clairaudience or clairvoyance, using that spell’s range—provided air can travel between the shaman and the target area via an unobstructed path. This doesn’t require line of effect, meaning the path can turn corners and go through spaces as narrow as 1 inch in diameter. The shaman can use this ability a number of rounds per day equal to her shaman level, but these rounds do not need to be consecutive.
