Azure Rain Cloak

Made from the substance of a rainy Feywild afternoon, the garment looks and feels like a normal wool cloak, except that it keeps its wearer completely dry in the rain. When the cloak is spread out on the ground, it becomes a pool of pure rainwater roughly the size of a bathtub.

Water can be taken from the pool slowly using up the cloak's material, making it shorter every time it reverts to a garment. You can turn the pool back into a cloak again by grabbing the water’s edge. The cloak contains 32 gallons of water, but only weighs 3 lbs. You can replenish or destroy the cloak's supply of water by casting create or destroy water on it while it is laid out on the ground. Each casting restores or removes 10 gallons from the cloak. 

A character needs one gallon of water per day, or two gallons per day if the weather is hot. A character who drinks only half that much water must succeed on a DC 15 Constitution saving throw or suffer one level of Exhaustion at the end of the day.
