A beautiful silk fan that depicts a scene showing a ship in peril on a stormy sea.

 Enchanted with the soul of a fused storm elemental, the war fan can summon a violent storm over any target area within the sight of the one calling the storm.  The storm will start small, only 1/2 mile across, but will grow to 10 miles across within the span of 1d10+3 minutes.  The storm will produce dangerously high winds and lightning strikes (a 1 on a d100 means someone is struck nearby and will take 10d6 lightning damage).  This tumultuous storm will last 2d6+4 hours, producing flood conditions due to the amount of rain it calls.  It will not rain again in this area for 3d8+2 days.

Should the war fan approach its own storm, or become engulfed in the storm, a 40ft radius circle of perfect weather will surround it.  (However, you will still be subject to the effects of the storm, such as waves, or winds, or floods).  The magics of the fan can only be called upon once in an eight-day, and only if the actual sky is visible to the one calling it.
