A Tengu fan which, when used, sends forth mighty gust of wind.
This fan has three charges, all of which are recovered at the end of a short or long rest.
When used to blow air, the fan expends one charge, and causes a gust of wind in a 20 ft. cone from the user. Creatures within this cone must make a DC 17 Strength saving throw. Creatures that fail suffer 3d6 thunder damage, are knocked prone, and pushed 20 ft. away from the user. Creatures that succeed are not knocked prone nor pushed away.
