Bag of blinding sand

While called "sand" this magic bag is filled with a gritty mixture of finely ground glass and banshee pepper extract. The bag contains enough "sand" for 3 uses (3 charges), the contents of this bag magically replenish after a long rest. Delivery is simple: when caught in an act of some questionable morality, blinding sand is flung into the face of the witness, increasing the thief’s odds of a clean exit.

As an action, you consume one charge and fling a handful of dust at a creature within 10 ft. of you, the target must succeed on a Constitution saving throw with a DC of 8 + DEX modifier + Proficiency bonus. On a success, the target is immune to the effects of Bag of blinding sand for 24 hours, as it will not be caught off guard a second time, and isn't blinded. On a failure, the target is blinded for one minute or until it succeeds the save. The creature can repeat the saving throw at the end of its turn.
