Redcap's Corner Pathfinder
Prerequisite: four air techniques
As an immediate action, you can channel a cyclone of swirling airs around you, for a number of rounds per day equal to the number of air techniques you know. These rounds do not need to be consecutive, and you can end the effect as a free action. While this ability is active, arrows and bolts directed at you are deflected upward and miss, while any other ranged attack (except for a giant-thrown boulder, a siege engine projectile, or any other massive ranged weapon) passing through the barrier has a 30% miss chance. Additionally, gases, most gaseous breath weapons, and creatures in gaseous form cannot pass through the barrier, and while protected in this way you gain Whirlwind Attack (Core Rulebook, pg. 137) as a bonus feat for which you need not meet the prerequisites.
