Bag of Infinite Sand

This small pouch seems to contain sand. The bag weighs 1 pound.

You can use an action to turn the bag upside down and speak one of three command phrases, whereupon an amount of course or fine sand (your choice) pours out of the bag. The sand stops pouring out at the start of your next turn. Choose from the following options:

• "Pocket Sand" produces 1 pound of sand.
• "Sand Bag" produces 10 pounds of sand.
• "Sand Blast" produces 100 pounds of sand that gushes forth in a geyser 30 feet long and 1 foot wide. As a bonus action while holding the bag, 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. Instead of a creature, you can 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.
