As an action, you can throw a handful of blinding powder at a creature within 10 feet of you. The target must succeed on a DC 12 Dexterity saving throw or take 1 slashing damage and become blinded until the creature spends a bonus action cleaning the blinding powder out of their eyes.

On a failed save, a creature takes 1d4 thunder damage and is blinded and deafened for 1 minute. On a successful save, the creature takes half as much damage and isn't blinded or deafened. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
