Bag of Blustering Winds

This looks like an ordinary leather bag, tied tightly shut and bulging at the seams with its contents. It weighs no more than the oxhide from which it is made, for the bag contains a miniature one-way portal to the plane of elemental air. You can use an action to untie the bag. Once the bag is opened, it creates an effect identical to the casting of the gust of wind spell (save DC 15), except that it does not require concentration, but does require a free hand to direct the bag’s flow. It may be opened three times before it is emptied for the day, but it refills at the next dawn.
