Decanter of Endless Water

You can use an action to remove the stopper and
speak one of three command words, and water
pours out of the flask. The water stops pouring
out at the start of your next turn.
"Stream" produces 1 gallon of water.
"Fountain" produces 5 gallons of water.
"Geyser" produces 30 gallons of water in a geyser.
As a bonus action, you can aim the geyser at a
creature within 30 feet of you. The target must
succeed on a DC 13 Strength saving throw or
take 1d4 bludgeoning damage and fall prone.
