Pocket Sand is sand kept in your pockets. No, seriously though. It's literally just sand...you have in your pocket. What do you want from me?
Pocket Sand is a multi-use bit of cleverness that involves throwing. As an action, or as an Attack, you can throw your pocket sand on the eyes of a Large or smaller creature within 5 feet. Make a Ranged Attack against a creature, treating the pocket sand as an Improvised Weapon. On a hit, the target is blinded until the end of its next turn. A creature blinded in this way can spend an action rubbing the sand out of its eyes to end the blinded condition on themselves.
In addition, you can use your bonus action throw the pocket sand to set up an attack. When you do so, the creature must make a DC 10 Wisdom (Perception) check or the next attack against it has advantage.
