Windstorm

Routine (24+ hours) As long as the windstorm persists, the effects of wind on movement are in effect. Overland travel in a windstorm is treated as if moving through difficult terrain. Once every 8 hours, attempt a DC 18 flat check; on a success, a randomly chosen PC who isn't sheltered is struck by debris. Debris Strike [Single Action] The targeted PC takes 2d6 bludgeoning damage (DC 16 basic Reflex save).
