Decanter of Endless Water

"Geyser": Produces 30 gallons of water that gush forth in a geyser 30 feet long and 1 foot wide. As
a bonus action while holding the decanter, you
can aim the geyser at a creature you can see within 30 feet of you. The target must succeed
on a DC 13 Strength saving throw or take 1d4 bludgeoning damage and fall prone.
You can instead target an object that isn't being worn or carried and that weighs no more than 200 pounds. The object is either knocked over or pushed up to 15 feet away from you.
