Bag of Blinding

A small burlap bag tied with a leather string which contains an infinite amount of sand. As an action, you can reach into the bag and throw sand into the opponent's eyes. The opponent must succeed a DC 12 constitution saving throw or be blinded until the start of your next turn. The bag starts with 2 charges and regains 1D4-1 charges per day. It cannot have more than 4 charges built up at a time.

"Pocket sand!"

Notes: Blinded, Throwing sand is considered an improvised weapon attack, so you add your strength modifier to your attack roll
