Bag of Winds

A medium sized, light brown cloth bag, seemingly empty, but closed with red string woven into/around the mouth

• Holds 5 charges
• When the bag is opened, 1 charge is expended, casting the gust of wind (DC 14) spell from the mouth of the bag. The creature holding the bag must make a DC 10 strength save or the bag flies into the air, propelled by the spell, after which it magically closes itself and lands 60 feet away from its starting position in a random direction determined by rolling 1d8.
• Each minute the bag is open expends 1 more charge and casts the spell again.
• The bag regains all charges each day at dawn.
• If the fifth charge is expended, the power of the spell is tripled, its DC increases to 21, and whoever is holding the bag must make a DC 17 strength save, or the bag flies into the air, propelled by the spell, after which it magically closes itself and lands 180 feet away from its starting position in a random direction determined by rolling 1d8.
